Wow! Thanks for an intelligent response rather than coming back with the
guns blaring.
OK, maybe I'm wrong with the 1,500 mile oil change. I dunno. I will stick
to the 3,000 miles, however, esp on the older cars. On my Scion I set the
'reminder' to 4,500 miles since that car is running synthetic.
However, I also take into account other factors. If the oil looks dirty,
out it goes, but not before 3,000 miles. There have been times I didn't
change the oil right at 3,000, but usually before 5,000. If at 3,000 it
looks dirty, it goes.
Toyota engines run hot, and heat doesn't help motor oil at all.
I also occasionally treat it to some Slick 50, too...
