I use it in all my vehicles, I will not change the oil in my diesel if it's not available but how is it in small engines?
Doc & I must be twins! I only use Shell Rotella 15w40 in every single engine on this farm. From my smallest tiller engine to our V8 Massey's. No need for various oils here. No engine failures at all....well a busted radiator roasting engine doesn't count! Rotella all the way!:thThumbsUI use Rotella in everything I own. I have for years, I have never lost a engine. Most BIG Truck shops use Rotella and most big truck Mechanics like Rotella also.
When I owned Ozark Truck and Auto we bought Rotella ,two 55 gallon barrels at a time.
