Wiki has it as a court action which Mobil lost and which "loosened" the definition of what a synthetic oil -is- . The problem is with the word -virtually- which of course fits the topic under discussion perfectly - there are no true full synthetic oils if there were the bottles would proudly...

Gentlemen, I readily admit that my knowledge on the topic is somewhat limited with regard to the chemistry however one does not have to be a chemist to know that there probably is no such thing as a true 'full' synthetic motor oil unless one is paying $30 or so usd/qt. Which one of the big boys...

My issue isn't with the performance of one type of oil over another central to my problem is that I thought, and yes silly me, that a full synthetic oil was simply that an oil -manufactured- using synthetic, read; man made (or person made) components. To discover that those so called full...

What did it was getting a reply from a major maker of engine oil refusing to to inform me if paraffin is in their oils, said it was proprietary info; there are many synthetic blends and very very very very few-if any- true synthetic oils. In fact the most synthetic of the synthetic just may be...

I am convinced beyond doubt that the term 'full synthetic oil' is categorically and unequivocally a marketing term and nothing else, further more I am positive that one would more quickly find an honest member of Congress before discovering a -true- full synthetic engine oil. A sincere thank...

Not really -terms like 'legally synthetic' and an article ('99) which begins with: 'While the field is not wide open, a new ruling confirms that the definition of "synthetic oil" remains largely in the hands of marketers" pretty much confirms that the old advice is still the best advice: caveat...

I know more than I did AND found a great thread on this site on this very topic BUT the conundrum remains: which is the true synthetic-the one with or without paraffin ?

Tnks for the replies. I would like to keep the question brand non specific if at all possible. For cost reasons, as an experiment, I recently switched to a different oil, brand name, labeled -full synthetic- I learned after the fact that it contains paraffin (does not qualify it as being...

Curious-does/should an oil containing paraffin preclude it from being labeled as a full synthetic?

I will admit to being severely a/r, o/c about oil changes with our '07 6.0-E450 rv-about every 4k max miles using Amsoil for the last 100k or so, yes I really do know I have way-way overdone it but one does what one must do. A question for the smart people here-as the miles start to rack up...

any labs recommended for coolant analysis ?

Appreciate the replies.

When a lab uses the wording 'inference of coolant' just what exactly does this mean?

Look into Amsoil Marine/Diesel series-its the only stuff that stays in our '07 6.0 which we bought new, motorhome -also check out Stanadyne Performance additive, 150k zero oil consumption and original injectors plus about 60% better fuel economy than the V10. The big BUT is that in the vans the...

Our VW TDI's would run perfectly with any diesel oil our '07 6.0 PowerJoke E 450 slurps oil with anything other than Amsoil Marine/Diesel - go figure.
