If you simply went by the oil filler cap, no TSB would have been needed. The reason Toyota is doing this is to improve their MPG average anyway, but what I find interesting is that these 5W-20 and especially 0W-20 oils only come in synthetics! So Toyota stock brand for these engines will be synthetic or at least a blend. This puts to bed the argument FOR DINO ONLY debates. 0W-30 is still an excellent oil and provides better protection. I believe that a synthetic 0W-20 or 5W-20 will still provide excellent anti-wear benefits though.

This was discussed very much on many forums when these TSB's came out. The conclusion was that if your specific engine is not listed, use what the oil cap says. I bet if you find someone with a new Yaris (recently made) and get them to check their oil cap, it will say 5W-30.

Well it could be you had higher oil pressure because some passages were partly blocked restricting the oil flow. Using an engine flush and using synthetics will remove the deposits and may be causing the low oil pressure
OR maybe he used a lighter oil.
OR there could have been a build up of crud in the sending unit.
Synthetic don't tend to thicken over time like mineral oils do either so you may see slightly less pressure on the guage

If it's a huge drop I would recommend testing the oil pressure.
If it's a higher mileage engine use a slightly heavier synthetic oil say a 10W-40

[Black Yaris]

what do ya'll think of 0w40 it is a very common weight oil for European cars

[07WYarisRS]

That would be perfect for an engine with high mileage

I run 0W-40 in my motorcyles

This thread has bee a very good read.

I am planning to change to synthetic in the spring.

My current mileage is 10,000 km.
From reading the previous posts, it seems like an oil flush is not necessary when changing from conventional to synthetic at lower mileages (ie. 8000 km a lower)

I'm planning on changing to synthetic perhaps around 14-15K km, depending on the weather.

Should I perform an oil flush at that estimated mileage, prior to using synthetic?

Can't hurt. A flush will just make your oil stay (look) cleaner for longer by removing any contaminants in your crankcase.

Couple of questions... I'm planning to take a road trip around christmas, and I think I should get an oil change as well as a "just-in-case" checkup before I go.

So I'll be going synthetic after reading the wealth of information in this thread.

Question #1: Redline, Amsoil or Royal Purple come is as highly recommended, but over here, as far as I know, are not available. Mobil 1 seems to be all right too, but what about Castrol? We can get GTX, Syntec, Magnatec, and so on, are they any good? Or else there's the usual Shell and other common brands.

Question #2: It's the tropics here, temperatures only vary between about 25 and 40 degrees Celsius, and I see that most oils sold here are 0W30-0W50, does the ambient temperature make a difference or should I stick with a lighter oil like 0W20 as recommended here?

Thanks!

You can order Amsoil online or I can put you in touch with my Amsoil guy and either he can ship it to you or know of someone or another place to order Amsoil from. Redline is also An excellent lubricant. Royal purple is decent but has had quality control issues in the past that I have seen first had with lab test results. Things like high copper levels, water and even grades being off. I would stick with Amsoil or Redline.
The rest like Mobil 1, Castrol Syntec, Motul, Qstate, pennzoil synthetics etc are all just highly refined crude/mineral based oil. IMO not worth the prices they charge

A 0w-30 wont hurt in any temp however if you live in a tropical climate a 5w-30 is all you really need. Stick with the 30W oils, 20W oils are super light. While they can help mileage ever so slightly too light of an engine oil on a car under heavy load orextremem temps or high rpm operation can shorten the life of the engine.

I'm from Costa Rica and we don't have Amsoil or red line oils.
These are the brands represented here:

Penzoil
Castrol
Shell
Mobil
ELF
Qstate


Do you have any experience with any of those brands? Which one would you recomend?

if they have mobil there then just use mobil 1 synthetic or if you wanna go the extra length just go onto amsoils website and order it

Here is a comparison of oils. http://www.1st-in-synthetics.com/10W30API.htm

You are one lucky dude! Do you use Amsoil PI? (Performance Improver)

[d2dailly]

i will use amsoil 5w30 not sure what the preformance improver is but they carry a bunch of ish from amsoil and i get it for less than $5 a quart :)

[elsteverino889]

I think i already posted... but MOBILE 1!!!!!!!! My yaris only deserves the best and when i went to Mobile 1 for my first oil change i told them nothing but the best they have. no other oil can compete with synthetic mobile 1 oil
