Ok so I guess my car have thick oil so gonna do a oil change my question is what brand best for my car they told me to get 5w-20 but what brand should I get syntheic or conventional my car have 13k miles close to 14k
5W30 shouldn't hurt the engine, but it won't let the MDS system work so your fuel economy will suffer (but your fun factor will not!). I'll send you a PM regarding the specialty stuff I use.
