Re: E-TEC oil
NOSLEEP,<br /><br />You are correct about the difference in ratio.<br /><br />From what I've been hearing, TCW-3R and TCW-3RL oils have to pass more stringent test standards than TCW-3 rated oils. This whole oil rating thing is going to be revised in the not to distant future. Industry rumors are leading to a TCW-4 rating. I'm not certain, but I would bet the RL thing has to do with the higher crankcase and combustion chamber temps of the DI engines, probably the solvents and other additives not flashing off too soon, so the oil does its lubricating duties better.<br /><br />Why doesn't the dealer know? Probably too busy with business to keep up with the rest of the industry or (hopefully not this) he doesn't care.<br /><br />-John<br /><br />BTW, "Hi" back at you too DJ, I've been around occassionally, but just too busy to post recently. You'll be seeing more of me around.
