It burns oil possibly worn valve guide seals. A friend told me to use synthetic or high mileage and it should help a little. Since i burn about a quart a month ive used everything from this to little known brands. My car still runs fine, passes inspection, no check engine. Oh by the way using a synthetic or a high mileage did cut down on oil consumption. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Name brand without the high cost. *by R***E on September 15, 2026* Great value for the price.
