Steelies!
"May be"?
Drove one?
0w-20 is a weight you don't come across often. What's the benefit, out of curiosity?
First and foremost, you get to keep your warranty. It's the spec.0w-20 is a weight you don't come across often. What's the benefit, out of curiosity?

Versus 5w20? Less viscosity at startup. Given the weird shit these motors do at cold startup (all sorts of pulses and pops and shit on every single one I've talked to the owner of), I'm willing to give them the benefit of the doubt on it being a necessary thing to keep it from lunching itself. Once it its temperature it's identical to 5w20, 10w20, 15w20, or in fact straight SAE20.
It's 'uncommon' in that it doesn't appear to be chemically possible to get 0w20 with conventional oil (in that I've literally never seen it), but it's a common stock item for synthetics, at least here. Walmart carries it, FFS.
It's more the 20 that is odd to me. The lowest operating temp viscosity commonly available here is 30, i.e 0w-30 or 5w-30. I've never seen anything-20 in an Australian auto shop.
Interesting. Sounds consistent, since it goes away within seconds of startup.Pulses...pops..chatter...common to boxers with piston slap. Initially due to the 2.5 block on EJ25s it would be due to the bore dimensions. Im surprised even with the new block it does the same, with the Toyota DI and also the 86mmx86mm bore of the block...On older blocks the recommendation is to let the oil "warm" up as it would reduce the chatter...guess its inherent to the design.
