Do the newer Jeep GC have a cabin air filter?
I'm thinking of buying one and my wife has bad allergies. Riding in vehicles with a CabinAir Filter seem to help her.
It is my understanding that in order to achive the new API certification, 10W30 oils have a spike of synthetic oil.
Take Valvoline, is the 10W30 All-Climate the same formulation as the Dura-Blend 10W30?
Do anyone know for sure? Why buy the more expensive semi-syntheic when the conventional oil...
