If you use Mobile 1 Synthetic which one do you use??
Red Cap@ 15W-30?
Green Cap@ 10W-30?
Blue Cap@ 5W-30?
I imagine for around this time of year it would be better to use the 10W-30 but I'm not sure. Everything I've read on different forums always mention the Red Cap but I think they live in warmer parts of the world. Would Green Cap be okay? Opinions?
