I use royal purple in mine and it depends where you live to what weight you decide on, i use 5w-30 in myrtle beach, but usally you want to use the same weight your car calls for. but when it comes to the brand, royal purple is the one i choose, it is a little more expensive but its great. and whatever you do, dont get your oil changed at WALMART. they purchased me a new oil pan if you know what i mean.
