Rotella VS Valvoline
So ever 7.3 i've ever owned i've run nothing but Rotella, but here recently i had a friend recommend trying valvoline. I normally run Rotella 15w40, but instead i changed my oil yesterday and tryed Valvoline 20w40 with a half gallon of Lucas Oil Stabilizer.
My first impression of the Valvoline is WOW, i love the way the motor feels, soo so much smoother idle and crusing along, seems a bit quieter too, and even starts easier. With Rotella i had the real loud first crank when the truck started, almost sounded like it was startin dry. But with Valvoline its nothing even close, smooth start, smooth idle, smooth everything.
So what im askin is for opinions? Or does anyone think the higher viscosity will hurt the engine?
And while im askin i usually use Fram filters but went with a Motorcraft this time.. Yes i know Motorcraft is the factory Ford equipment, but is it as good or better compared to others?
All help is much appreciated.
