You might think about switching to 5w-30 for the winter. It's slightly thinner and will better during those cold Michigan winters. I'd suggest plugs soon as well as changing out your tranny and rear diff if not done yet by previous owner.

I use Mobile 1 5w-30 synthetic oil. Change it about every 6000 miles now, and switched over from regular oil at 3000 miles. At 40K, if it has not been done already with the 30K service you should have the fuel filter changed, air filter, brake fluid changed, and coolant fluid changed out. Plugs do not need to be changed until 60K, anything else is up to you.

If you can get Royal Purple dirt cheap, do it. My past experience with a Saab 9000 Turbo with APC in Germany, frequently, on the autobahnen at 130 mph+ for extended periods. I'd recommend synthetics in a turbo car. It's not mandatory, but it is a good idea, if you drive hard, to run synthetics as they don't break down like dinos.

This is rather odd, but I'm gonna inject some interesting fuel into the fire. I work for Valvoline, and although I know that in general it is better to use Synthetic in turbocharged vehicles because it has a tendency to break down and "coke" in the turbocharger, it recommends in our manuals and is even on one of our certification tests not to use full synthetic or synthetic blend is any Subaru. I'm not sure what would be the reason for this, if any, but I thought I'd just let ya'll know...

hmmm ... it would be very interesting to know why. IIRC the WRX manual says that synthetic is OK but to keep the same change intervals.

Also, the WRX should run 5W30 year-round except maybe in very hot conditions. I like Castrol GTX dino.

I run that mobil 1 15w-50. Should i be using a 5w or 10w? I just figured living in Florida 15w would be my best becuase of the heat. What would be the advantages or disadvantages to running a lower weight oil?

15w50 is probably not a good idea... the manual is pretty clear about what weight oils to use for varying temperatures.

If I lived in FL, I'd be running 10w30 year round.

As for synthetic, I don't particularly care what Valvoline says... my SUBARU owner's manual says synthetic is fine after the break in period.

15W50 is too thick; you will not get proper lubrication when you first start the car up. 10W40 is as thick as I would go even in Florida. The outside temperature is not that critical since your engine gets way hotter than that. Its upper temp is determined by the cooling system and will be pretty much the same no matter what the air temp is.
