I am currently using Mobil 1 5w20. I have recently read an article that 5w20 does not do so well with high heat. I was think that i only starting having the issue with my car when it gets hot out. In the article they stated that 5w20 does not lubricate as well when temperatures are higher than 80 degrees outside.
I was just wondering what oil weight wveryone was running with what mods. thanks in advance!
