Thanks for the help
The time frame is between oil changes (3,000 miles)And it isn't the same amount every time
Also sometimes I'll check my oil and the level will be low,like maybe a quart and a half low, so I'll wait a day and the next time I check it it is right where it should be. I'm starting to get used to waiting a day or until after the next time I drive the car for a second reading,
does this sound familiar to anyone ?
