This is the Toyota dealer bulletin link if you have access which states Toyota dealers to use 0w-20 oil. Toyota Service Information & Repair Manuals

Problem solved..go to a Toyota dealer. Buy genuine Toyota 0w-20 oil. Doesn't cost most. Change it every 7500km. Close thread

Cheers legend.

Was this bulletin due to supply chain constraints on other oils or is it simply due to more specific climate and temperature conditions inherent in Australia?

 

Doesn't say. Don't think it would be for supply constraints as dealers can get their own bulk 0w-16. It's probably due to climate / warranty / engine reliability

 

I wrote to Toyota Australia, asking them what was the details of Toyota Service Information & Repair Manuals and they said they could not comment on it, as I wasn't a Service Professional. Seems you have to have a login to read it.

 

I always use 0w-20 weight.
I live in warm climate, extreme driving conditions meaning sitting on the stop and go nowhere traffic.

I'm going with the 0w because of cold start pump ability. But really it never gets that cold.

I've read numerous articles and YouTube clips and talked to various aeronautic engineers. And the new lightweight oils have so many Superior protection Additives in them now.

I don't really think there's a worry here on what weight you go as long as your cold start pump ability is no stress to the engine or top end once it reaches operating temperatures.

The concern I have is extreme running conditions. High heat, stop and go kind of condition so I will change it fairly often. This RAV4 is one of the easiest cars I've ever changed oil on.

 

My issue is the opposite. October to March well below 0C, sometimes 40 or more. I'm curious if 0W12 would be better for winter use here as 0W16 is recommended for normal use and 0W20 is "acceptable"

 

I have been reading that BMW and a few other manufacturers are going with an even lighter oil like you mentioned.

I would think 0w16 is adequate for most cold temperatures. But you could always try it in the dead of winter.
Really your biggest concern is pumping on a cold startup.

You could probably Google Bob the oil guy and see various comments on lighter viscosities.
Good luck!

The 2025 Camry and the most recent Corollas in the US are using 0w-8 according to the Toyota Nation forum.

 

Wow that's amazing! I know the technologies in the oil have so many great additives that make them super slippery. I've been running 0w 20 for about a week now moving away from the 16 weight. Summer's here now and it's getting pretty hot.
I don't see a whole lot of difference in fuel mileage, but I'm not really that picky about it. But I do hear the engine is a little quieter.

 

Yeah, American Petroleum Institute in September 2023 adopted SAE 0W-8 and 0W-12 viscosity grades into service category API SP, extending the bottom range of potential viscosity grades for North America’s newest passenger car motor oil specification.

 

according to the Repco website all Toyota dealers in Australia use Castrol Edge 0w20c5. Sparesbox too Sparesbox | Auto Parts, Car Care and 4x4 Accessories | Sparesbox

 

Castrol is what I like as well
