[QUOTE="Jaybird, post: 1156076, member: 22283"] Brian, It is hard for the consumer to know the bases in many of todays lubricants without doing some searching. Any oil on the shelf that does not state it is a synthetic will be either group I group II or most likely a mixture of the two. I&II are the conventional petroleum oils we have been using for years. Some of these conventional petroleums may also contain an amount of ester or other type of synthetic chemical in the formulation. Not enough to claim a synthetic base, but enough to really add to the performance of the oil. With oils that claim to be sythetic in composition, we may have to look at the oils MSDS sheet to get a clue as to what the base make-up really is. Mfg's aren't real keen on everyone knowing their recipes and often times will be a bit vague on the MSDS, since they really don't have to list the full formula. "Highly refined petroleum oil" could fit for either group II or group III synthetic. The term "ester" could be a multitude of different acids, esters or derivatives. Word of mouth from insiders who like to spout on the net is the best way to learn what the majority of oils are made of. Fairly common knowledge that all Castrol synthetic products are now, and have always been, group III hydroprocessed petroleum oil. It seems that Mobil has now started to take the same route with their synthetic lines, whereas all of their synthetic products in the past have been mostly PAO synthetic. I think it easier to list what we know as to contain PAO now, as to list the ones that don't... Boutique oils like Amsoil, Maxima, Motul, Redline, Royal Purple, etc...still are using PAO and esters in a majority of their formulations...you pay for them dearly too. Most any 0w car oil will probably be made of PAO. Heavy duty oils like Rotella, Delvac, and Delo in the 15w40 grade are all conventional oils, while the 5w40 synthetic in those oils will be group III petroleum. Bill, I think the Delo is probably one of the finest lubes on the shelf. After all, Chevron owns the additive package company that makes the add packs for many of the top oils of other labels, as well as their own. They make sure that their products are top notch and robust. Their Chevron Supreme passanger car oil is probably the best shelf oil for the buck there is...it's just hard to find. Some have steered away from Delo in the past because of the higher amount of moly that they use. But, I stand firm on the moly scare being a big load of hogwash for the most part. Moly is a good thing, and it proves itself consistantly. I've never heard of anyone who actually used Delo to ever report of a problem of any sort. [/QUOTE]
