use synthetic motor oil and switch the folowing 1. the timing chain2. the exust system the catlitic converter is too close too the engine. 3. do a tune up and radator and tranny flush.also check on oil coolers because the engine over heats because of the catlitic converter and the oil passeges are too narrow. if you hear pining or knoking have your veichel engine cleand. this only applies to 2.7 liter not the 3.5 or 3.2. good luck!
