    Hello , i am asssuming that the engine is a 3.1 litre engine .. The best oil to use is giong to be 10w30.. these engines are notorious for the lower intake manifolds to leak coolant , if it is leaking it needs to be replaced along with the oil change.. If the vehichle has dex cool coolant in it, replace it with the normal green coolant or a universal type coolant ,, dex cool eats up gaskets, and creates many other problems
