i am... i havn't noticed anything out of the ordinary. seems a little louder at start-up. maybe a little thick for the Winter, but on the back it says it flows at the same temp as the 5/30 i normally run.

Liek Westy said, 15w50 may be a bit thick if you live in the cold north.. Otherwise it's fine...

Castrol's 5W50 Syntec is good for all season too given its viscosity range.

I don't know if Mobil1 has a synthetic oil with that range, you might want to check it out.

i use the mobil 1 15w50 in my wrx wagon and also used it in my turbo legacy sedan.let the car warm a little on start up. i hope the new formula mobil 1 holds up as the old 15w50 did for me.

I use mobile one, works just fine in my oppinion. I have been meaning to try some of the stuff they're selling through various subby sites on the internet, just don't have time. Mobile one's easy to get to and it's synthetic, just try to do as well for your car as you can I guess...
