Help with oil change specs

[TheSilkySmooth]

Mobil 1 5w-30 is not full synthetic just 30%, Castrol Syntec has no synthetic in it, Valvoline Synpower has no synthetic in it - what "full synthetic" are you running? IN North American market, synthetic oil doesnt have to be real synthetic. Pretty much a joke - on us. High detergent / long drain "synthetics" can and do show higher engine wear than your 2 buck a litre conventional petrol oil. The detergents compete with the extreme pressure boundary additives (zinc compounds). High detergency is not a plus on a passenger car or race car.

If you are going to ask such a question, it seems like you might post a few links to sources which support your position.

I see this all the time. "This or that vendor's synthetic oil isn't really synthetic." But rarely do I note any sort of reference to credible sources making a clear statement on the matter, based upon clear evidence.

Besides that, I have to wonder why there's such a focus upon what's thought to be in the oil, and such a lack of focus upon how, empirically speaking, the oil performs relative to other oils.

That's why people become so weary of oil threads. There's always a lot of bluster by folks who imply they have the facts in hand. But rarely is there any actual meat to the claims.

If someone made a questionable or surprising statement, I too would ask their source and then perform some research, myself, to validate. The information is out there in foreign MSDS (typ Korea and Japan where full disclosure is required) The P/N are the same as North America, so we will assume its the same formulation. This issue to me is consumer deception and cost. The Mfg cost on a group III base stock are 1/2 that of a PAO or PO Ester. Europe does not allow such foolishness as labeling a conventional oil a synthetic. I would post the PDF file but EXxon-Mobil tends toward RTF HTML not downloadable PDF.

Here is a Castrol true synthetic that you can buy in the US, (I usually find it at AutoZone), but yeah its made in Germany. http://www.bobistheoilguy.com/forums...&Number=718643
