Mobil1 recommends Mobil1 ESP 5W30. So, ACEA C3.
Yeah, but since when do we treat Mobil 1 and Castrol websites as official oil recommendations? As I said, Toyota only uses ILSAC/API for their gasoline engines. C3 is also mid-SAPS like ILSAC/API -- that's why Castrol and Mobil 1 may recommend it. Chances are that the oil is also certified for SN; so, whether it is also C3 is a moot issue and not a Toyota recommendation.
Russian Toyota owner's manual recommends SN 0W-20 for 1AR-FE and 2GR-FKS. So, it's neither 5W-30 nor C3. And if you think Germans drive their cars fast, you should see how Russians drive. The language is the same as in the US manual with a thicker viscosity may be more suitable for high speeds or extreme loads. The Russian manual also says, "If you use SAE 10W-30 motor oil or oil with higher viscosity at very low temperatures, problems are possible when starting the engine; so, for such conditions, the recommended engine oil is SAE 0W-20, 5W-20, or 5W-30."
As I said, the only difference between the US and international oil recommendations for Toyota is that in the international manuals, thicker grades are put explicitly in the temperature chart. The recommended grade is always the thinnest grade in the temperature chart, even in the international owner's manuals. The sentence about higher viscosity may be more suitable with high speeds or extreme loads is also the same as in the US manuals.
Mobil1, and especially Mobil1, will never recommend oil unless recommended by manufacturer. One thing about Mobil1 is that they are very clear what is approved, what not, what is recommended and what not.
As for who drives fast, yes, I drove in Russia, but one thing is being idiot and another driving from Munich to Hamburg and keeping your car constantly at very high rpm's. You are confusing what driving fast means. Germany has fastest roads in the world, yet lower death rate per one million driven miles than the US, where speed limit is very strict. So, it comes down to many factors, but autobahns are generally very hard on engines.
When I was working as test driver we were pretty much living in Germany. Middle of the night on auto bahn gives you unique opportunity to truly test some components. Maybe one can do that in Russia, but you never know whether Russian military is going to decide to park a tank in the middle of HWY, or whether they will forget to pave part of the road. Something like that cannot happen in Germany.
