Been runnin 0w-20 like the Toyota TSB said in my car for the last 2 oil changes, getting better fuel econ

[Black Yaris]

if you realy want me to I will find and post the offical Toyota TSB if ya'll do not believe me

[Kaotic Lazagna]

i believe you, but i want to see the TSB. i've never heard about it before, and like i said, i thought it stood for Toyota Service Booklet.

don't think anyone here's doubting you though.

[Go4th]

i was guessing from when i purchased the car 6 months ago what i read.

it says 10w-30 may be used however it should be replaced with 5w-30 at next oil change.

i thought it was 0w-20 but it is 10w-30 that could be used.


copy and paste what you found black yaris

Do some more internet homework/research....you will find that RP is not the best synthetic on the market...there are more better like Mobile1 and especially Amsoil...still, RP is better then any mineral....

But what if one lives in 100 degree summer weather?

It does not state.... A Prius also takes 5w-20 or 0w-20 synthetic oil from the factory, even states it in the manual
so why would it matter where you live, and what temp it gets?
One of the whole reasons of switching to synthetic oil is that it does not break down as fast, heat being one of those major factors.

Mobile1 class III Synth
RP class IV Synth
Amsoil class IV Synth

in your words, as stated above"... RP is not the best synthetic on the market... ...there are more better like moble1..."

Hey Pavel put that doober down man, it is messin with your head

[Kaotic Lazagna]

well, i ended up buying Mobile 1 full syn. 5W-20. RP doesn't have a 0W-20 and the store manager said to get Mobile one instead of RP. they didn't have 0W-20 in stock for the Mobile 1, so i ended up getting 4 quarts of 5W-20. i bought a Napa Gold Oil filter because the SM said it's the same as Wix.

i read all of the replies here when i get back. i have to pick up my laptop now...

[Black Yaris]

you will see a pretty good differance once you switch, you will be happy that you did

[Kaotic Lazagna]

okay, i think the next oil change that i'll be doing is within the next 9k or 10k or sooner miles, just to let what ever remaining conventional oil out. from then on, maybe 10-15k mile intervals.

[Black Yaris]

every 5000 miles is the way to go bud

[Kaotic Lazagna]

i thought they last longer than that?

[Black Yaris]

as stated before, we recommend still changing your oil at 5000 miles for 2 reasons (1) warranty issues that may come up down the road (2) sellability to next owner ( on your schedual that would only be 6 or 7 oil changes in 100k miles, I would not buy a car if someone only changed there oil that often)

[Kaotic Lazagna]

so going with the synthetic route won't really save me much money?

[Black Yaris]

yes it will in gasoline, I mean it is your car you can do with it as you wish, we are just giving your recommendations. Or why don't you do the happy inbetween and change it every 7500 miles or so to be on the safe side?
