Doubtful; but, why do you do that?

Well, here's why. I grew up with the notion of getting oil changed every
3000 miles or 3 months, whichever comes first. I don't use synthetic oil and
I doubt if the quality of oil has gotten better over the years. I doubt if
the metals in the internal parts of the engine which need an oil film to
prevent metal on metal contact has gotten any better either. So I'm sticking
with what I grew up with. Is it overkill? Maybe. But I'd rather err on the
side of caution. Aslo, when it comes time to sell, putting myself in the
shoes of whoever may buy the car from me, I'd rather see that service was
done more frequently than every 5000 miles. Now I'm sure 5000 miles is a
reasonable interval or Toyota would not be recommending it. I guess I just
think that 3500 can't hurt.

I'm not an expert, but I recall API SC oil was top dog when I was young. Now
it isn't available for any service AFAIK, and the standard is API SM. The
oil we had in the "change oil every 3000 miles" days isn't fit to keep our
tools from rusting anymore (hyperbole). As one of the regulars in the
alt.autos.honda forum notes, sludge used to be expected

has any trace of sludge it is a big deal.

I use the schedule in the owner's manual for each car. For my daughter's
Honda that is 6000 miles, for our Classic Prius it is 7500 miles the way we
use it. But to each their own.

As an aside:  Several years ago Consumer Report decided to look at this and
used a number of NYC cabs for the test.  Half had their oil changed at 3000
mile interval and half at 6000 miles.  Major brand API oil was used and at
the end of the test series they could find no discernable difference between
3000 and 6000 mile intervals.  I went to 6000 miles between changes after
reading that.
