I've been running _only_ synthetic (either Mobil 1 or Pennzoil
Platinum 5W-20) and my engine is happy. Because I live where it is
sub-zero Farenheit, I don't like the idea of gelled motor oil in my
engine until it heats up. For the couple of extra dollars, I can't
think of a better way to prevent unnecessary engine wear.
For people who live in warmer climates, I guess it isn't an issue, but
I live *up North,* and it -definitely- is an issue. It goes below
zero here quite often.
