Hi. I have a 97' Chevrolet Lumina, 3.1 L, V6 engine. Millage = 137,569 and I would like to know, what brand or kind of oil I should use. The oil cap says to only use 5w30 oil. I always use the regular Castrol 5w30.
So, what oil do you recommend me to use? Mobil, Castrol, Penzoil, Havoline...? 5w30?
Thanks
