I sent in some oil samples to analyze to determine what would be the most ideal for my 5.0 Supercharged V8. I am currently using Liqui-Moly Special-Tec. I only drive about 4k miles per year and get annual oil changes so I dont think it will make much of a difference but I do drive like a little old lady, rarely going over 3000rpm's. I live in Maryland and keep it in the garage most of the time so I guess my only concern would be carbon deposits as I dont really do "Italian Tune-ups". What do you think is best for my situation? I have below the Liqui-Moly Special-Tec, Motul 5122, and Ravenol ECS.
