I use Royal Purple. A friend of mine has some pretty expensive cars and he swears by it. Besides, I put about 3k miles on my car in a year, I change the oil in the fall and that's it.
Best engine oil and tranny fluid to use?

I have been using Elf Sythetic. Yesterday I had them put in 5-30 just to try them out, and it is awesome!!!
AMS OIL hands down. Mobil is up there too, but for wear and friction testing, AMS does better than literally every other oil. Reason Mobil is a close second is because both AMS and Mobil are the only 100% non paraffin based oils.
