</font>( I have only use synthetics in all our turbodiesels simply due to their extremely high resistance to oxidation and degradation by the excessive heat load imposed on them by the turbochargers.
I'm not sure that you understand basic chemistry regarding synthetic oils, oxidation of hydrocarbons or the operation of turbochargers. Read up in some of the books I've referenced for you so you can understand why. )</font>
None of your response addressed my question: How much better off are you? I should also follow up with, "How did you measure how much better off you are?" I can answer both questions for myself. By running dino oil in some vehicles and synthetic in others, I could detect no measurable savings for me by spending the extra money on synthetic. I had no oil failures in any of the engines I've owned and so far, they've all left my possession under their own power without $1 being spent on repairs related to inadequate lubrication. How's your story go? Different?
As far as my knowledge of chemistry, turbos, etc., goes...well, I'm going to guess that it's at least average so I don't feel that I'm really operating at a big disadvantage. That stuff is nice to know but not really germaine to the issue. Is it reasonable to expect an oil purchaser to have taken chemistry in order to make a choice of oil? Or is that a smoke screen to try to make it sound as if only those with a chemistry background can make an informed choice on oil? I don't think you really need to know any of that...all you gotta do is look at the bottom line: Did it save me money? It takes --ZERO-- hours of college chemistry to be able to figure that.

Excellent, you've already convinced yourself 100%!
I bet you could do allot better than that though. Do to the fact that you've never had any problems with lubrication of turbodiesels, you should extend your filter and oil changes out 3X or 4X or maybe even 5X, it just goes to show that your wasting good filters and oil.
A 40,000 or 50,000 mile change out schedule to take advantage of your excellent results is warranted to lower costs even more. Like you said, oil is oil even if you don't know or understand anything about it. My college roommate never changed the oil or filter in his car in four years, just kept adding a quart of the cheapest dino oil he could find every 300-400 miles when the lifters started knocking real loud and he sold the car with 225,000 miles on it and it was still running good but it did have allot of blue smoke in the exhaust . He did not know anything about chemistry or oil either, but he sure was an excellent salesman! /forums/images/graemlins/grin.gif
