1. Subaru Forester 2.5 XT (EJ255=STI block, different ECU, different intake manifold, and a WRX turbo)
2. API SL/GF-3 5W-30 recommended for fuel economy; 10W-30 & 10W-40 allowed over -4F; some straight
grades and 50 grades also allowed in severe conditions. Subaru now recommends 3,750 mile OCI's with turbo's due to oil supply line screen blockage/sludging and owner's not checking oil often enough.
3. Central New Jersey
4. I drive hard, but not necessarily fast. Short gearing on the car makes it quick to redline.
5. Daily drive is seven miles each way. At least once a week I hit WOT/redline after about 30 minutes of driving (in addition to my regular commute). I drive on the beach in the summer, do some light off-roading, drive spiritedly in the twisties and hills, do some highway miles to the beach, and drive to SC 2-3 times per year. No track or auto-x.
6. At ~62k miles, my turbo was replaced due to excessive oil getting past the seals. This was going on for about a year. Turbo oil supply line screen was clean according to the head tech at the dealership. The turbo itself was fine. The new turbo lasted 20k and then blew. The shaft had excessive play, but there were not other signs of damage and again the oil supply line filter was clean.
History:
After a run on M1 5W-30, I stuck with GC for several years. I wanted to try Amsoil out of curiosity, and had decent uoa's with that.
Here's my last uoa on SSO. Anyone think the slight uptick in lead was a sign of things to come?
After two runs on SSO, one on DEO, one on dealer conventional, I'm currently running RL 5W-30.
I'm thinking of switching to Motul to support some Subaru forum sponsors and since they support Subaru motorsports. Most of them carry Eco-nergy 8100 5W-30 (thin, but I had a decent uoa with it), X-cess 5W-40 and 300V. I have found a couple that carry X-Lite 0W-30.
I've also thought of just sticking with Red Line or even going back to GC. The biggest difference that I've noticed with RL (and why I want to stick with ester based) is that start-up is quicker than with any other oil that I've tried. I probably will not try a GF-4 oil.
