I'm using Rotella after reading the threads on what kind of oil to use because of the lack of certain additives in todays oils... I don't know if it made a difference no way to check I'm just going to change my oil every 2000 mile... Old blue Canadian tire has the Lucas on sale once in a while...
I was interested in what SPAREPARTS had to say about adding it to the steering box did it really make turning your truck easier???
