Poll: Which FULLy synthetic oil do you use?

[Yawesh]

for those who use fully synthetic oil for their engines

i am now using Royal Purple after my factory break in oil (changed at 5100k)

[jambo101]

I usually use Mobil1 but due to extreme cold i got my mechanic to change the oil and he used a product called Lubri/liqui Moly http://www.techmax.ca/lubri.htm. Same price as Mobil1 and seems to work just fine on my 01 Echo.

[2006fronty]

I use Mobil1, I've been thinking about running Amsoil though

[ChinoCharles]

I use Royal Purple because the hillbillies that live amongst me swear by it and if there is one thing I know it is that hillbillies love their engines. Doesn't hurt that its a track staple around here, too.

[ROCKLAND TOYOTA]

I use Mobile-1. Why? I guess I've always held it to be the standard among synthetic engine oils. I'd certainly switch to another synthetic brand if it were that much better. same here and im up for a change if it will help.....

I use Royal Purple because the hillbillies that live amongst me swear by it and if there is one thing I know it is that hillbillies love their engines. Doesn't hurt that its a track staple around here, too. :laugh:

[mikenacarato]

i use royal purple because were dealers for it so i get it at a good price. other than that, i wouldnt use it

[CASTREX]

Where is Amsoil on the list?

[Yawesh]

Where is Amsoil on the list?

lol, sorry. wished i could fit more

[Altitude]

I'd buy Amsoil if it were more readily available through retail outlets.

BTW, wth is Vavloline? :iono: Are you trying to piss off SilkySmooth? :wink:

[Doc Zaius]

Amsoil!

[CASTREX]

lol, sorry. wished i could fit more

Well, then you need to remove one of the options you have there because I know several YW members use Amsoil.


Amsoil 0W-30 Signature Series FTW!!

[CB900F2]

Amsoil 5W30 (ASL) with EAO OIl Filter.

[Klink10]

Amsoil 5W-30 XL changed between 4000-5000 mi. usually at 4500.

[Yawesh]

Well, then you need to remove one of the options you have there because I know several YW members use Amsoil.

is there any way to edit it? can mods help out? thanks!

which should i remove in replace with Amsoil?

[Klink10]

I wouldn't worry about it....just count the number of posters who write in AMSOIL.

[YarisSedan]

Amsoil high performance oil with K&N filter

[yarstar]

AMSOIL 0W-30 Signature Series with EAO filter

:headbang:

[talnlnky]

i've used mobile on two changes, and castrol on one change.... didn't really see any change in mpg's.... MAYBE 1mpg...hard to tell.

[Kaotic Lazagna]

Amsoil with their long life (EA?) oil filter. One time oil change every year! hehehe.

[Inspector14]

I have always been a mobile 1 user. I have changed that though, today.

after doing some research i have found that Pennzoil Platinum is cheaper and seems to have a lower viscosity at cold temperatures (i live in alaska) than mobile 1. i was going to use Valvoline SynPower, but that was a dollar a quart more for similar performance.

bought 4 quarts and a mobile filter for 26$ at walmart, and changed today.

bah.... after doing more reading. both synpower and pennzoil platinum are group 3. as are castrol (made in usa, german is group 4) and even some M1 products are group 3. in 3K miles im switching again to Amsoil (a true group 4 PAO), there are dealers local to me so i can get a case for 120$ or so.

[gid]

SHELL full synthetic 5w-30 for both YARIS , $4.30 a qt. w/ tax . Before , PENNZOIL Platinum 5w-30 ( P.P. 5w-20 for short stint in both ) , and 1 round of VALVOLINE Synpower 5w-30 . Basically any of these syns that are under $4.50 a qt. with tax . Tight :moon: .

[gid]

Checked, GENERIC ( Exxon , Shell ) for the SHELL full synthetic :wink: .

[FunctionSpec]

I buy whatever Synthetic is on sale.

[aca72]

I buy whatever Synthetic is on sale.

+1

[GeneW]

My dealer put in Castrol for the free oil change but I usually use Valvoline Synpower, 5W-30.

Gene

[ddongbap]

Nobody noticed its CASTRO, not CASTROL?

[cleong]

I buy Carlube fully synthetic (not sure if you guys have heard of the brand), its about US$20 every 4 litres. It gets changed out every 6000 miles so I don't believe in buying ridiculously priced oil.

[ROCKLAND TOYOTA]

Nobody noticed its CASTRO, not CASTROL?

:laugh: didn't want to upset the masses though.....

[eTiMaGo]

Nobody noticed its CASTRO, not CASTROL?

A brand with high fidelity :bellyroll:

As for me, currently using Blitz fully synthetic 5W-40

[500snakz]

You guys might want to check out a brand made in japan for it's domestic cars. It's called ENOS. Really good oil that is used by a lot of tuner guys.

I use mobil1 0W40 in the srt 10, and plain conventional mobil 10W30 in the yaris(free oil changes at dealer for life).

Oh, you guys know I just HAVE to reply. Only Redline, some Amsoils, and some Motuls are TRUE synthetic oils. EVERYTHING else is just dino oil being marketed to you as synthetic - what a FARCE. And only group: V is the good one. So, no one runs the REAL good stuff except a couple guys here who run Motul 300v. Man, try some group V stuff if you want to see what a real synth does, Otherwize you are just paying for 'premium' mineral oil - which is what all API SM should be anyway.

Check this:
http://www.kemopro.com/productinfo/engine.html

I'm considering trying it next OC; even if its just SJ


ps: HA, see I didnt mention that, according to Ashland, Mobil-1 5W-30 doesnt even meet the current american petroleum institute standards and causes excessive valvetrain wear on cold starts - I AM getting better:tongue:

by the looks of the chart , MOBIL's advertising campaign has done them well . Good CAMPAIGN , big oil execs pop the CHAMPAGNE :drinking: . :bow: . :wink:

Amsoil 5-30

[CtrlAltDefeat]

wow the Amsoil site (http://www.amsoil.com/storefront/asl.aspx) says under normal wear to go 25,000 miles between OC... I was worried about going the full 5000 with Mobile 1... been changing it at 3000 (like me ol' grandpappy did) since I bought my car. (call me wasteful, call me old fashioned, call me a tool of Mobile 1s marketing department, but I usualy try to err on the side of caution)

but there's not one competitor against mobil one accordign to the results

[TheSilkySmooth]

Tell me the cheapest, TRUE syn oil please. I dont know about CHEAP, but Motul E-tech 5W-30 in the GM or Renault citroen spec should do the trick for toyota warranty . I think some Mod shops are gray-marketing it in the US - like LTB motorsports. Probably cost $10/litre shipped to your door. Then there is some redlines and Amsoils - havent tried them (yet!)

[TheSilkySmooth]

Mobil, Bose, Dunkin Doghnuts, Flat screen LCD HDTVs, Bailouts, Toyotas - Americans have quickly become a bunch of ignorant zombies - the lemming effect! Question EVERYTHING! Time for a resurgence of the SKEPTIC philosphy - gee maybe I could start a Skeptic religion and get a tax break...

[PolarWhite]

For those out there that think Mobil 1 is the best on the market, you need to do your research. Valvoline was running national ad campaigns claiming that there full synthetic oil provided 4x better protection than Mobil 1. Mobil 1 sued and their case was thrown out when Valvoline showed up in court with the independent lab tests showing the results. They also did more testing and found that the current Mobil 1 formulation does not meet the minimum API SM or ILSAC GF-4 specifications either. Seems they have been resting on their laurels and got behind the rest of the industry. I love it. I have the letter right here in front of me.

[Sodium Duck]

Just changed my oil today. Amsoil XL 5W-20 extended life sythetic, and a Hastings filter. Can't wait to get out and run about now.

I was so stoked to find these for sale at my local car joint -- I didn't realize he was an Amsoil dealer. I actually went there because I thought he was a WIX dealer. Turned out he wasn't but had Amsoil instead. I love when the universe balances out.

sorry about it. i wished i could remove pen-rite now heh

if mods can do anything , that would be cool

if not, i guess by posting and/or voting for "other" would do

once again, sorry. so many legions of Amsoil users!

danks for contributing. did you also vote on the poll? thanks again

Yup :thumbsup:

[POORSHA]

amsoil 0w30 ss, every 15,000 wether it needs it or not. amsoil filter as well

[justjesus]

WOW !
I thought I was one of the only crazy people that would use Amsoil. Reading from the posts, i guess not.

Poorsha, every 15k??? SO i guess every 5k would be too soon?

[Sodium Duck]

Who's using Motul? I did some quick research and thought it was something specifically for drag cars... But then others were saying it is the only TRUE synthetic?

Is my Amsoil a true sythetic?

Is my Amsoil a true sythetic? Check the Amsoil site (I wouldnt ask here and risk 3rd party hand-me-down info)But, how's that amsoil 5W-20 working out? Trying to figure if it makes the engine noisy when fully warmed or if it doesnt like to rev above 4-6 grand without sounding like it would grenade. Your amsoil should be real synth blend - as is redline and some other garage-made specialty stuff. Some guys use the Produit Du Frances Motul 300v but i am haviing no real good luck with the correct Motul 5w-30 Eco-nergy. but Eco-nergy is a grp iv PAO synth and I like only group iv-v blends or the full on group-v polyol Diester jet engine crap that has a pour point of -60F. I don't have the inclination anymore to use the next step up E-Tech (ester blend) motul - Ill just slum it next on some Valvoline fake synth or Penzoil fake synth and join the rest of the world I suppose . - the bro

[marcus]

ok my post got kicked out but here it is..

sorry guys i know theres alot of mobil1 fans in here but based on my tracking mpg , based on same temperature weather, same driving habits..i just notice big difference switching to amsoil...what brought me to amsoil is the friction issue with mobil1...google guys.

here my track record.

toyota conventional oil 5w-30 averaging 580km / 36liters summer

mobil1 5w-30 averaging 555/ 36 liters summer as well
mobil1 5w-30 ave 495km /36 liters winter

amsoil 5w-30 havent done the tank yet but noticed increase on half a tank by atleast 25-30kms .. this should give me an average of about 540 km on a 36 liters for winter.. we shall see..

im not advertising guys so easy on the comments..this is just my track record shows. surprise amsoil is not the the lineup for me to vote..

[ChinoCharles]

Thanks marcus. :thumbsup:

[jkuchta]

I'm using Motul 300V 5W-30 (di-ester base), and I love it. Engine revs fine all the way to redline at the track, and I'm getting 37-39 mpg in the street. It's a little pricy and difficult to find, but IMO its the best stuff out there.

I don't use synthetic because A) it is very expensive and B) it doesn't really offer any advantages unless you are really revving your engine or have a high performance engine. dont fall for the hype.

Off the dino oil since '07 :thumbup:

[TheSilkySmooth]

Check out Motul BMW specific LL-01 5w-30 ester based. Should be great for you hot shoe guys who dont want to spring for the 300V plus it should be good for 7500-9000miles OCI easy with maybe 1 filter changeout. It's a bit thicker of a 30wt compared to the eco-nergy 8100 5w-30 that I found is pretty thin and you cant wail on it when you want to.

[GeneralDon7]

I use Mobil 5W-20, and it increased my MPG by at least 4 if not more. The engine also starts a lot easier now then when I had the conventional toyota oil in it. Anyone know what oil the one user on here that has over 200000 miles uses?::iono:

Be good to know that but a sample of -1- is not statistically significant. Plus HW driving at 3000rpm is Easy on the motor. My engine got too noisy on the thin oil, ANd I'm talking thin 30wt. I cant risk the 20 you motor may be diff - Tight like Wirgina =o <----

He uses cheap oil he picks up at Walmart. No kidding. It's in one of his threads.

[talnlnky]

ok... So here's the million dollar question....

Do all the oils sold in the US under "synthetic" that are actually these API group 3 oils.... do they protect engines any better than the normal oil that we would buy for a fraction of the price.

Should i go with a "normal" oil that costs me $2.xx - $3.xx a quart versus a castrol/penzoil/whatever for $6.xx a quart?

I've been under the belief that the $6.00/qt oils do in fact last longer, and have better cleaning/filtering properties.... is this not true?

I don't really care if my oil is a "true" synthetic or not.. I just care if the extra few dollars I spend actually nets ANY advantage/protection.

[Altitude]

From trini_per4mance: (the 300K mile Yaris - quote ripped from YouTube)

"I use Wal-mart Super Tech Synthetic 5w-30 oil with OEM Toyota filters which helps maintain the right amount of oil pressure in the motor, unlike the non-oem filters. "

[Benggolf2]

Mercedes Benz recommends Mobil 1 on all their AMG cars. Have been using Mobil 1 on our C32AMG (sold) and C55AMG for years and never had any engine issues.

Guess what's good for MB-AMG should be good enough for the Toyota motor too, eh? :biggrin:

[33OH]

Amsoil.

[nsmitchell]

I switched from Mobil-1 0W-30 to Valvoline 5W-30. It may be all in my head, but even on chilly days I seem to be getting about 3-4MPG better MPGs. Sounds crazy I know but it seems to rev more freely. Usually on chilly days I would get about 28 to 30MPG with M1, with Valvoline, I'm getting about 32-34 MPG on my daily round trip to and from work. The only change I've made is the oil. I also switched my Fit to Valvoline 5W-20 and my wife has been driving it. We'll see how it does.

I have not seen any documented performance advantage that the "fake" synthetic oils sold in the USA ( Platinum, mobil-1, Syntec) have over a SM GF4 mineral oil (which are now semi-synthetic even though they dont say so). They may prove a bit better in the frozen north due to less heavy paraffins, and the Platinum has Honda HT06 approval for Honda Turbo use. I dislike Pennzoil so - noyt for me. personally after killing ALL my engines to early in the past 5 years with this crap US spec oils, I would only run the real stuff imported from Europe: Total(ELF), Motul, Fuchs, Pentosin, Haven't tried Amsoil yet. May give the ATM blue cap Amsoil a try, Better to give my $$ to the good ole USofA other than the EU.

[41magmag41]

Not to open a can of worms with this post, but I'm wondering if the added expense of Synthetic Motor oil is a waste of money in the yaris. Toyota recommends oil changes at 5000 mile intervals and has yet to recommend the use of synthetic in this particular engine. They do suggest that once synthetic is used to continue the use through the life of the car. Being that this is an economy car and we all bought her because of the lack of cost with upkeep why move to the cost of sythetic oil. I change my oil every 4500 to 5000 miles at the dealer because he runs oil change specials, 40 bucks for an oil, filter and tire rotation, and toyota trained techs do the work. I have over 49000 miles on my girl and get 36 mpg in the winter with no hard starts and 41 during the summer. Unless I see a post that shows me that there's an increase in mpg and reduction of wear on the engine I think I'll stay with the convetional oil at this point until and if I start doing my own oil changes again.

Again not to start a posting war just my two cents worth.

[1stToyota]

You'll do fine with the dealership oil changes. All makers that offer both always state that their synthetic outperforms the conventional, so it's a no brainer for me.

[MadMax]

41magmag41

Do what works best for you. What we are seeing in this thread is a lot of opinion and individual results, but I have yet to see any links to verified studies not sponsored by a particular oil company. There seems to be a lot of badmouthing of Mobile-1, but I've used it for years and have yet to have any engine damage because of it. I am not saying it is the best oil out there, it probably isn't; but it also isn't as bad as some claim. And there are a lot of other variables that factor into increased MPG results, not all associated with oil.

As long as you are doing regular interval oil changes within the guidelines of the manufacturer, you will be alright...

[Giobatera]

I've always used Castrol, no particular reason other then always being able to get good prices on it. But after this threat, I'm considering changing it to Mobil 1

[41magmag41]

Couldn't have said it any better. I've driven most of my vehicles to the 150000 mile mark and all ran as good as the day I bought them. My point was why increase the cost of operation with this vehicle when if you follow Toyota's guidelines she in all probability will go 200,000 with little or no work other than routine maintenence. Do what works for you and gets your girl to the 200,000 plus mark without added expense.

[ka0sx]

Val. full synth 5-20.
I have been using this for years, I can not atest to any of the other ones since I dont use them. But going from regular to full synth is a big difference.

[toad]

just put in some pennzoil platinum 5w-30. hope to see a big difference from the dino oil!

But you still prefer Mobil-1 to Mobil's conventional oil, correct? I think that's sort of what 41magmag41 was getting at; why synthetic over conventional.

[Stoln]

I use Mobile 1. If it comes as a factory fill on Corvettes than it is good enough for my Camaro and Yaris

I didn't see any noticable improvement in fuel economy when I switched to synthetic. But I do my own service, plus Pennzoil Platinum 5W30 at 3.99 (O'Reilly's) a quart it's too good of a deal to pass on.

[Giobatera]

For those of you who know any advance auto part store, they are having this special thru April 22nd. 5 Quarts of CASTROL Full Synthetic Motor Oil AND a K&N Performance Oil Filter for $24.99 plus applicable taxes. I'm not sure if it's nationwide. I leave in south florida and they are having the special here. I encorage those who want to find out more, to check their website and check by putting your zip code.

I would never take automotive advice from someone who shamelessly admits to KILLING all of his cars engines in the past five years...:rolleyes:

The man clearly doesn't know how to care for a car or its engine.

I am an Automotive component engineer and (past life) NIASE Master tech and race engine builder. We had a bad spate of Denso filters that were killing both suzuki and toyota engines. Our Suzuki and 2 toyotas use the same filter. The Toyota Rav was serviced by Toyota with genuine toyota motor oil and Toyota filters at under 5000 intervals. The vehicles are also not garaged in the winter. Thinking about installing block heater the coming winter.

just put in some pennzoil platinum 5w-30. hope to see a big difference from the dino oil!
It is dino oil, but its been severe hydroprocessed. But it's suppose to be one of the best grpIII oils out there as is Valvoline Synpower. Let us know how it runs!

Since you have this thing against what you consider to be fakes, funny that you'd pick blue cap Amsoil...you're meaning the XL series? It's group III and ACEA A1/B1 nothing too special about that. No, Ist, its the 10W-30 PAO base meat-and-potatoes product. The dealer doesnt sell amsoil anymore so I just put some Valvoline grpIII/IV Synpower 10W-30 in for the meantime. I hear the Amsoil doesnt have API SM/SL certification.
On the grpIII - I just havent had any formula work well for me YET. And I jumped on that ISO syn bandwagon with the Chevron Process when it first came out. Good luck with the P-Platinum its had really good UOAs as has V-Synpower. It's just Mobil-1 that has high iron and Cu consistently and failes to meet its API certs down the road. Funny that Mobil Clean 5000 is a good sleeper Dino oil.

For those of you who know any advance auto part store, they are having this special thru April 22nd. 5 Quarts of CASTROL Full Synthetic Motor Oil AND a K&N Performance Oil Filter for $24.99 plus applicable taxes.
I hope this helps! :biggrin: Isnt the K&N filter just a STP with a nut welded on the bottom? A company "Champion Labs" make the Bosch and Mobil-1 and K&N and Delco and most the no-name brands like Supertech for wallmart. That is a good deal you talk about, but I wouldnt pay over 10-$ for a 4$ filter with K&N's name on it. Just remeber Castrol Syntec is not real synthetic oil, It called group III severe hydroprocessed. If you want the real stuff you need Motul 300v, or Total Quartz Future 9000.

Amsoil does have API certification. Like I said, it's only on their XL series, which is API on every XL grade, and XL is ACEA A1/B1, and like I also said, it's group III. I posted the link from their site where it states they went group III to keep it competitive, pricewise, so they could offer API approved oil to the market. I think I did see a blue topped 10w30, and yes, it wasn't certified, and not group III, good for 25K, guessing A4/B4.

Ahh gotcha on the XL. I wasnt looking at the grpiii so I didnt read into it much. Here is a question I'm not fully clear on: Does Toyota warranty require API cert or is this just a recommendation/guidance? I'm assuming the emission warranty requires the use of low saps so you have to stay with an SL/SM rating. But certification IDK ....

[Giobatera]

It's all good bro! For the price, I still think is a good deal, specially, nowadays, that EVERYBODY or at least most people are doing everything to save a buck or two!

I thought it was pretty much common knowledge for the last 15 years or so that the oil had to be API approved, here in the U.S. ...and that's sort of been the problem at most of the forums I've been at over the last few years, a lot of people want to run the better oils, but they don't always have the API approval stamp on the front label.

[uncleyaris]

Where's Asmoil on that list?

[ozmdd]

Q-Horsepower. Not on the list, but qualifies for the highest spec in the EU. Can't remember the alphabet soup/number that was used, but its different from API and SAE ratings.

[sbergman27]

I've been using Mobil1 since it was first introduced in the 70s. Scamsoil not making the list is amusing. I'd steer clear of any company promoting 4 ball wear test results for *engine oil*!
