I finished off all my Red Cap and now it's time for another oil change and I can't decide what to use. I'm tempted to run the Shell Rotella syn but it's only 5w40 and it's going to start getting hot here so I'm not sure if I should run less than 50. I had a gallon of the Mobile 1 ext perf green cap that I was going to use but changed my mind. I'm feeding that stuff to my lawn mower and pressure washer just to use it up. After it's gone, I think I'm done with Mobile. Seems like they intentionally screwed us by dumping Red Cap to force us into their motorcycle products and I'm not gonna bite.
