Dammit Herb, you just gave me another thing to worry about . But thanks for posting that link. I don't recall reading it. I use Rotella because its the only 1 gallon bottle that has a "window" that lets you see the oil level in the bottle. The Mobil bottle is all black and its difficult to determine if you've poured in the required 6.5 quarts. I have yet to even pick up a Delo bottle. I'll be stopping at Autozone on the way home.
