After discovering this site, I have made the decision to try GC (green or gold) in my vehicles, as well as performing UOAs. Both cars are lovingly maintained with Castrol Syntec 5W-20 & M1 filters every 3K. Based on reading a great deal of posts, I am comfortable with using GC in the Infiniti. However, I'm not convinced that GC is best for the Acura RL; posts concerning GC compatibility in Honda engines and the mileage is nearing 99K miles. Also, the Acura is a short-trip, in-town driver.
Based on engine, mileage, and usage, will GC be a compatible oil for the Acura?
Concerning UOAs, when should I send the sample? (3K miles or sooner?) Which analysis parameters will determine that the oil should be changed? Is there a sample report that indicates the mins/maxs for each parameter? Which parameters indicate engine problems?
Undoubtedly these questions have been answered in other posts, but perhaps mine will pull the information together.
BTW, this is the greatest site on the Internet!
