Who would have guessed 1928, or 1950's ??

To the average consumer, dino oils are perceived for all intent and purpose as old tech, and with synthetics perceived as new or newer technology.

I am aware only that Moble 1 was the first synthetic oil available back in the early 80's, but lately have read claims from Amsoil as having been first with synthetics back in the early 70's available to the consumer.

I like most are at the mercy of the market guru's and want to believe....

There is another way to look at drain intervals...most people posting here are talking about using synthetics to extend time between intervals. However, if for example one changed oil every 3K with dino vs. oil change every 3k with synthetic, would the result under this study be that the synthetic user had a longer lived engine?

This is a no brainer but extending drain intervals as talked so much about is for convenience, more time to play golf, even if they don't change it them selves! I look at it as exteneded service life! And what the hell do they care, their going to be in a new car every couple years anyway! Why should most people care about what ever happens to their former ride after they get rid of it?

I'm almost always the end user of most any meterial product, be it a car, computer, or even the cloths I wear, are all second or third hand. So I personally look at extended service life, vs. convenience! Without it, I'd never have a Benz!

What is your thought? BB
