RE: Castrol Edge...I can't say that I've run across this oil before, and this is the first time it's been mentioned. I'm not an oil engineer and didn't stay at a H.I. Express last night, but I'm guessing that the BMW engineers recommended 20w50 for some decent reasons. I don't have my owner's manual, but I believe the temperature ranges might have recommeded 10w in colder climates but no lower.
I'm pretty much tapped out on the oils that I had planned to test. I posted earlier earlier the different oils I'll be testing, which includes two common Castrol products. At this point, I think I'll have to stick with the current list.
