What oil should use for winter I usually always keep 10w30 never used anything else? I like in Massachusetts btw
Also my oil pressure is alil wacky it goes from mid pressure at idle to just about all the way high when accelerating. I've already changed my sendingunit like last year so would a different oil be not a good idea.
Btw I got a 94 3.9 extended cab with like 213k

 

Whatever the factory recommends. Should be in your owners manual.
