Hmmm Fred the chemist... Ok Fred i'll give you a testamony. I hereby testify in the positive for whatever jiffyLube has on sale on any given day. That's what is in my stuff and I swear by it. I have a hunnert and fifty thousand miles on an engine with that oil in it..changed every 7,000 miles or so if it needed it or not.
After all those miles the oil level only drops 3/8ths of a quart or so between oil changes. LOOK at all the money I have saved in the last 7 years on that one engine alone.
