If that's what I think it is, it was a polyol ester base oil with pretty much the same additive package you'd find in any motor oil of that era. I think pretty much all of the modern synthetics (that are really synthetic) use polyalphaolefin base oils but I may well be out of date here. --scott -- "C'est un Nagra.

A real controlled lab test would be better, but cost an arm and a leg. I didn't notice any mention of filters in the article. --Vic

No matter what the test results, there will be people with vested interests that will complain that the test was flawed in some way. Some people complained about the taxi test because they though that there weren't enough cold starts (even though there were about as many as the typical driver would do per day). Others complained because it was all stop and go city driving. Others complained because the engines in the taxis were not high performance, tight-tolerance engines. Suffice it to say that those who sell synthetic oil, or that have almost religious beliefs in it, were not pleased with the results of the taxi test.

Not pleased with the CR taxi test? I don't really care. I don't drive a Chevy Caprice or Ford Crown Vic, I drive a Camry. Besides, CR said that there was no significant difference in engine wear. They did not say there was no difference. Other tests conducted by BMW (and others) have claimed different results, which is probably why they specify synthetic as factory fill. Since the auto industry is in deep trouble right now, I sincerely hope that people would keep using conventional oil (and switch from synthetic to conventional oil) and purchase new cars more often, so we can keep those people employed.

Where on earth did you get the idea that using conventional oil will require people to purchase new cars more often? |
