I bought a used 95 Dakota with 2.5 and 5-speed with 128,00 miles use. It seems to use a quart of oil every 225 miles. It is not smoking nor leaking and is a puzzle to me. I have changed the PCV valve,plugs,wires,cap,recent oil change. My 91 didn't use oil at this rate and it had a leak around the front seal. Any ideas would be appreciated. Thanks.
