Oil recommendation for DD/Autocross car

[pinkertonpunk]

Hey guys, this is my first post here, I am looking for some help. I have a 2007 WRX STI that I daily drive year round in Wisconsin and am looking for a oil recommendation. In spring through fall I autocross the car on a regular basis. I ran Amsoil last season and would like the switch to something cheaper/more available for ease of topping off between changes. The car goes through a fair amount of oil on race weekends. Do you guys think I should run different weights during racing season and during winter? Reading through a few posts, it seems Pennzoil Platinum seems to be a highly recommended oil that is readily available. I am sure I am missing some info, so feel free to ask.

Thanks!

Mobil 1 Turbo Diesel Truck 5w40. Fantastic oil. Very robust.

I'm running it right now and we are well into the negatives.

Something that might be a wee bit more difficult to find than the PP would be Red Line 5W-40.

If it were me, I would use Rotella syn simply because its more readily available for me locally.
Delvac syn will work great as well.

Funny you mention mileage. I've run everything from 0w20 to 5w50 and there were never any discernible effects on fuel mileage. But this is a 5.0L Ford, so YMMV.

I had great luck in a turbo with Mobil1 10w30. Highly shear stable and cranks easy when cold.

But not in an STI that is auto-x'd, IMO, unless you can find the 5W-40. Bang for the buck, I would consider Rotella T 5W-40. M1 TDT too, but then again you might be getting into Amsoil price territory. Whatever you run, do a uoa.

So you guys think then that it would be best to run a 5w40 oil then I assume regardless of the brand?
