1. I drive a 2017 Subaru WRX about 13000 miles
2. The manual recommends 5w30 full synthetic API SN of GF-5 across all temp ranges
3. I live in Southern California (IE if you’re local)
4. Its a sports car and I’m not going to lie, I tend to push it. But I always take it easy until oil reaches 150, and I let it idle for a few minutes before shutting down when I’ve been pushing it to let oil cool in the turbo.
5. By daily drive is around 20 miles with about half on freeway and half mountain roads.
6. My car is new with no known issues.
So, until now, I’ve been running subaru brand oil. I’ve been hearing that that oils is actually pretty cheap and prone to sheer in the turbo cars. I also only recently saw that mountain driving is classified as extreme conditions recommending 3000 mile oil change interval. I would like an extremely sheer resistant oil that would also allow me to keep the original 6000 mile oil change interval. I don’t mind special ordering oil, in fact I tend to mistrust off the shelf oil on instinct, but I would also like to avoid spending a small fortune if possible. I don’t care about resource conservation stuff as long as losing it would improve oil performance. I’ve been looking at Red Line oil and amsoil and I’m currently leaning more towards redline, but I wanted other options and ideas as well. Thanks in advance for your help.
Question #2 answered your question. Synthetic oil, 5W30.
