My 1998 Prelude uses oil. it always has. At first it was just a quart or so in-between oil changes. Now everytime I fill up gas, I have to add a quart. Is there any product that actually works and helps slow oil consumption? I really dont want to do a ring-job at 140KThanksPS I have already switched from 5W30 to 10W30. Aslo here lately, I have started to smell a little oil odor (like a drip on the exhaust type of thing after oil changes) If it is a leak aswell any sugestions on where to look?It does have, as always a film of oil or something on the back of my car, so that is why I feel that it is burning oil.The car's interior and exterior are in great condition, but at 140K I begin to ponder how much $ I should invest in the car. It has been flawless so far and I have had it since 32K.
