The thing is, the cost argument is a very good argument. I change my oil
every 3,000 miles, which works out to a little bit more often than once a
month. This adds up to a substantial cost in the end.

I'm not sure why you should expect such a difference, but if it makes you
feel better, that's fine.

The sludge problems on those Toyota V6es can be prevented with synthetic
oils, it's true. But they can also be prevented by religiously done
conventional oil changes every 3,000 miles.

I'm not. I use the synthetic oils anyway, because I figure that the cost
of an engine is so high that the added few hundred dollars a year is worth
it to me, and because I tend to drive cars until they have several hundred
thousand miles on them. I'm not sure it really makes any difference in any
of the engines I use, and if I happen to get a really good deal on conventional
oil, I'll use it for a few weeks until the next change and I certainly don't
see any short-term difference in doing so.

That's basically how I feel, although frankly I wish I were paying only
$30 a year for oil. Hell, I pay more than $30 a year in gear oil for
the transmission and differential which get done about annually.

Most any oil can do 10,000 mile in terms of providing lubrication.
Synthetics become acidic, and eventually become saturated with suspended
soot particles, just like regular oil. An oil analysis is a good
investment to determine the optimum oil change interval.

The synthetic base stock is better for low temperature start-ups, and
high-temperature continued operation, such as is seen in high
performance and turbo-charged engines.

I see. So what you're saying is that you have nothing to support your
recommendation.

So the truth begins to emerge, your problem is not synthetic oil or
lack of documentation but Amsoil dealers and MLM type marketing.

And your reading comprehension, at least on this particular post;
was very poor. He distinctly said he used synthetic oil for ten years,
but not Amsoil. personally I've used Syntec, Royal Purple and Amsoil and
would NOT recommend Syntec under any circumstances.
