Oil Question

[diablokicks]

Ok, good about synthetic, but what about the different types of dino oil, High mileage etc, any difference or all the same?

High mileage oil is the same as conventional oil, just labeled different. Mobil 1 seems to be highly rated as far as synthetic oils go, maybe right behind Royal Purple. I have heard nothing but bad things about Pennzoil. I use Mobil 1 or Valvoline in my Jeeps and Mobil Blue synth in my Powerstroke.

I thought high milage oils had seal conditioners and detergents that help older engines.
