what is the best oil to use on dodge ram 5.7 e (i have a p3400 code )And is expensive to fix the problem?
Pennzoil ultra is a great oil but hard to find some walmarts have it depending where you live or you can order it online.
Redline also makes good oil, Eneos Sustina
if your car is under powertrain warranty it will be covered by the dealer.
