I want to hear different opinions on the type of oil you guys are currently using. I am not discussing what oil is better, since different people have different preferences. I am running on Royal Purple 10w 30, i have not heard much about it on the forum. I believe my engine temperature is a bit cooler whit this oil, about 90 degrees C on average High way driving and about 93 on average city driving. Would like to hear from different oil users, and Royal Users if any.
