Which I have never had.

All my Toyotas have had oil change intervals of 7,500 miles.
I start chewing my nails over 5,000.
And the oil doesn't look terribly good at 5,000 miles. It pours out like
water when it's that old.

No, that is not the reason. As I said, I have rented may late model cars on
business trips and none of them has a better power train than my 1998 V6
Camry XLE. I do have about $2,000 in aftermarket stereo upgrades in my 98,
which does have some impact on my keeping it, especially since it is very
difficult to replace the crappy stock stereos with aftermarket gear on the
newer cars (they don't use DIN cutouts and the audio is integrated into the
dash).

Nevertheless, I will probably purchase a 2009 model. Some lucky person is
going to get my 98 (I have a couple of friends who want to buy it from me).

Since you, Mr Hunt, are a known advocate of only buying American cars, I
don't blame you for buying a new one every couple of years. I had an
American car I would do the same.

Switching to synthetic after even moderate engine wear with conventional oil
will often cause the problems you encountered. It is not good to switch too
soon or too late.

Of course, this is contrary to what some people have said in that
conventional oil and synthetic oil have the same viscosity (if you use the
same viscosity rating), so according to them your experience is a figment of
your imagination. In my experience, what happened to you is as would be
expected.

More likely the rings in Scott's escort were stuck and the additive
package in the Mobil 1 freed them up resulting in the increase in oil
usage.
The same thing could have happened if he'd have simply changed the oil
brand from Castrol.
I've switched many high mileage engines to Mobil 1 and never had a
problem.

Can you still buy Japanese Camrys in the U.S.? When we got our 1996, the
west coast had mainly Japanese-made models, and the East Coast had
mainly U.S.-built models. They were slightly different, as sometimes
when I buy parts they need to know where it was built.

It's rather ironic that more and more "foreign" cars are made in the
U.S., while more and more "American" cars are not built in the U.S..
