Originally posted by metroplex: I looked on the back of a 5w-30 bottle and it said "formulated from our synthetic/hydrocracked base stock..." Does this mean that their 5W-30 is a Group III engine oil?? I believe Conoco makes the Motorcraft line of engine oils.
quote:Conoco has never called its hydrocracked base oils "synthetic." As for why Ford has chosen to put this on the label, I suggest you ask them.
Originally posted by metroplex: I already know the 5W-20 is a Group III But why would Ford/Motorcraft/Conoco state that the 5W-30 is formulated from "synthetic/hydrocracked" base stock?
quote:You and Roger are absolutely right, Metroplex. I rechecked yesterday on a visit to WalMart and the 5W-30 bottles indeed say "synthetic/hydrocracked". Curiously, the 10W-30 bottles say "hydrocracked" only. Since they're the same price (only the 5W-20 quart bottles being about 50 cents more), I suspect it's a misprint having culled the ad copy from that of the 5W-20 - particularly since the 5W-30 bottles make no mention of "synthetic" on the front of the bottle as the 5W-20 bottles do. Sorry for my confusion.

quote:I read that as a Group III/ Group II synthetic blend base stock or what they used to call semi synthetic. Group II Isodewaxed and 2nd generation Group III Isodewaxed based technology processed oils have become somewhat blurred. Essentially both are are hydrocracked, the biggest difference is in the severity of the hydrocracking process.
