Help choosing an oil

[bgshiznit]

I just picked up my 2005 Subaru WRX and I want to change the oil ASAP. I've done lots of reading over the last few days about various oils, and I've learned a lot, but I'm still indecisive.

I'm going to use the car as a daily driver about 400 miles a week and plan to do some "spirited" driving.

A few people on the Subaru forums had recommended Mobil 1 5W-40 Turbo Diesel Truck. This oil is readily available at the local Wal-Mart, but is it ok to use in a gasoline engine?

I really need some guidance. Thanks in advance!

Doesnt Subaru recommend a 5-30 for that motor? Most of the import guys down here who drive those things all run Red Line 30's or Royal Purple 30's that I know of?

First off let me start by saying, nice choice! That year is one my favorite years of the WRX. Can't stand the 06+ redesigned grill. I'm not too familiar with the oil grades Subaru uses, but best of luck to you!

GC would do well in that car year-round in your state.

5w30 is "recommended" for the 2005 WRX (as well as my 2005 WRX STi), but you can use other weights as well:

I'd start with something a bit thinner than the M1 5W-40. Either M1 0W-40 or GC 0W-30 (which I use in my STi) would be good places to start.

BTW,

to BITOG!

Try the Pennzoil Platinum 5w30. It is a great oil and very reasonably priced.

I was able to find one place around me that stocks the GC 0W-30, labeled as "european formula". I just dont know how much longer they will be carrying it. The Mobil 1 products are all easily available as well as the Pennoil.

low mileage and spirited driving...

if the times you drive it normally you [get to full operating temp and stay there for at least 10 mins], i would go with Redline 5W30 or a 50/50 mix of Redline and German Castrol.

if you dont let it warm up completely i would do Shell Rotella synthetic 5W40 or an Amsoil oil that meets ACEA A3/B3 specs.

Shell Rotella synthetic 5w-40 would be a perfect choice....
