Shannow uses it in a Nissan diesel here in Australia. I'm sure he'll pop in a bit later.
A couple of other Aussies here have bought it recently, (Losiho and Maybe Toyota18, IIRC) but I don't think they've used it yet.
You could search under Formula R 0w-40 as well, as that is how it's marketed here.
Yes am using it in my camry not bad oil.Seems to be a oil with good cleaning action.MMM Fuel economy Mobil1 0w-40 is the best.But less engine noise compaired to Mobil1 0w-40.I might stay with this oil.Had a very good experience with Motul 300v 5w-30.But didnt like it due to no API rated oil.Some say BP Visco 7000 0w-40 and Castrol Formula R 0w-40 is the same oil with two brand names.Am not sure.
Yep, I'm using it in a turbodiesel at present.
It's giving me worse fuel economy than M1 0W-40, about the same as a dino 15W-40.
Being a diesel, I can't tell if it makes more or less noise than the M1.
Will go back to M1 next change.
