Oil Consumption
Define Minimal Oil Consumption
I always hear that 1 quart in 1,000 miles is normal oil consumption based on industry standards but I can't find any "published industry standard.” Can you clarify what is minimal oil consumption?
Oil consumption is very specific to vehicle manufacturer, engine size and design. Even within a specific engine model, normal oil consumption can vary quite broadly based on how the engine was initial...
Is a 10W-40 Motor Oil Better for a High-Mileage Pickup?
I bought a used 1997 Ford Expedition with 151,000 miles. It was dealer serviced and had frequent oil changes, but I do not know if synthetic oil was used. Upon purchasing the vehicle, I switched to Mo...

Increased Oil Usage After Switching Oil
I own a 2000 Saturn SC-2 with 110,000 miles that I have changed to Mobil 1 5W-30. After 3000 miles I have burned 2 ½ quarts of oil. This seems distressing. Can you help?
It is not unusual to use more oil after changing brands but 2½ quarts is excessive. We think you may have a mechanical issue or a leak that should be checked by a mechanic.
