I am picking up a very very clean '91 Subaru Legacy Sport Sedan with the 2.2L closed-deck EJ22T, turbocharged (no intercooler) to about 8psi. Car is all stock, very well maintained/lots of records, and 204K miles. Viscous center diff and rear LSD.
I have run Motul 300V, D1 5w-40, AMSOIL SSO, and Elf Excellium NF with good results in my '98 2.2L NA for many miles. Good UOA's. Availability is #1 alongside of cost. Mobil 1 0w-40 is another option, but not stocked in my local Wal-Marts any more, so cost has increased slightly.
I plan on running an AutoRX treatment first--- what would you recommend....just start using PP or Rotella Syn 5w-40 right off the bat? Those are my first two choices, I know I can't go wrong with those. Or should I do a good dino run while I do the AutoRX treatment?
The car will be autocrossed regularly and probably run street-pump 100 octane Sunoco or VP while being raced, otherwise babied and gas mileage squeezed out of it...yes, you can have both
I have had great luck with the AMSOIL Severe Gear 75w-110 in my other Subaru, so I see no reason to vary from this.
First OCI will have a long trip to Texas, where the family and I are relocating.
Opinions always appreciated.
