Here Comes Chaos.....
ok so new glow plugs and different oil. what besides 15w40 is safe to run i never have ran anything but
I've always run 15w-40. Now i'm running 15w-40 Amsoil full synthetic. Even in the winter time the truck spins right over and fires right up with no problems.
My blazer has 15w-40 Rotella conventional oil in it, and just by comparing when i fill the oil in the blazer vs when i fill the oil in the pickup, you can easily see how much easier the 15w-40 Amsoil flows over the Rotella.
