No the Yaris is a Mazda 2

That’s not the only thing that can happen from over filled oil. You can aerate the oil with the crankshaft counterweights

Sales tactics and they also get credits (or maybe just charged less idk) from the EPA for lowering the lifetime waste per vehicle. Hence the super long life coolant and long intervals for ATF, and the 10k oil changes

Nope that’s the bean counters. It’s an effort to reduce waste oil. I don’t think they recommend 15k on anything. Do it every 5k. Stellantis says their trans fluid is lifetime but the engineers that built the transmission say otherwise.

It does! It uses a 2 speed oil pump that requires the use of 0W-16 to lubricate probably on the low speed. But this guy probably knows better
