i was told to switch to a thicker viscosity oil to help with the problems of my 88 jeep cherokee pioneer, (4x4, 4.0, 6 cylinder). Is this really okay? it takes 10w-30 now. will switching harm my engine or any other parts of my jeep? any knowledge or advice?
what can i safely switch up to?
 
typically people switch oil thicknesses based on the weather. when it's cold a thinner oil is used and when it's hot a thicker oil is used. thicker will help the jeeps internal parts being as though the jeep is more than ten years old.
 
You should not have any problem moving up to a 15w-40 and in warmer climates you could move to a 30weight with no adverse affects.
