Few people? I think that a lot of knowledgeable car people do it, which may not be a bad idea if they use conventional oil. Obviously, that is excessive if you use a full synthetic.

You've attributed your use of synthetic oil to your engine running smoothly after ten years, when in fact there is no relationship between the two. Your engine would be equally smooth running on oil with a petroleum base stock.

The problem coincided with the switch to factory fill synthetic. I am not trying to overstate this break-in thing before switching to synthetic. But I find it ironic that most of the people who claim switching to synthetic immediately is not a problem don't even use synthetic and don't recommend it. Does it do any harm to wait until the first oil change to switch to synthetic? No, unless you live where the temps are below zero and you park outdoors. Could it do some good, even in 1 out of 100 cases? Maybe.

I can tell you without any reservation or doubt, that as soon as I made the change to Mobil 1 in 1998 (after the first oil change) I could feel that the engine revved more freely. Although I cannot prove that my 10 year old car is still in excellent condition is because of synthetic oil, but I have never had an engine run so smoothly after even 5 years. I frequently rent late model cars for business reasons, and very few of them are as smooth running as mine. Now, since you don't even use synthetic oil, how come you are telling me I am wrong? If you really want to get into serious discussion of cause and effect, then read some of the 18th century British philosopher David Hume who proved there is no known understood cause and effect relationship for anything. The tobacco industry has used this same philosophy to claim that there is no understood relationship between tobacco smoking and lung cancer (they are correct, because although there is an statistical relationship, scientists do not know how tobacco actually causes lung cancer). In fact, when the USDA evaluates drugs for the treatment of disease, they rely solely on statistical efficacy data, and not on any cause and effect relationship that may, or may not, be understood.
