JohnTDI, The problem with some early synthetics in aviation (Mobil 1 - PAO) was their inability to scavenge lead from rings and cylinders. But with newer formulas using esters and alkylated napthalenes, I understand this is no longer the problem it once was. Know enough about aviation chemistry to comment? Know anything of the composition of the Motul formula you use?
L8274, we all live and learn (myself included
) but it takes a real man to admit he was mistaken and admit another was really right all along. Welcome aboard.
On the issue of motorcycle oils, I'm convinced that there
is a difference between them and the emission-friendly automotive oils. But, I don't believe it is to the degree that it usually justifies their $8+ per quart price tag.
When I was a fireman, we used to see gear available from a fire department supplier and then see the same gear sourced elsewhere for less than half price. Add the words "fire-rated" and it doubled the price.
I also saw a local police department which bought a Tippmann paintball gun for over $600 for riot control when that same exact gun (they showed a picture) could be bought mail order (or even from a local paintball supply shop) for less than $200.
So, I like to see in threads like this one when people can post information which distinguishes between genuine elite products (or special applications) from the ordinary stuff with "specialty labeling" and a wole lot of additional markup.
