I have a 95 Impreza and I had my oil filled a week ago. When I checked my oil today, it was half full. I know that I do not have a leak because I park on a paved driveway and so I would see oil spots. I do not know what to do. I also do not know if this is a normal amount of oil to lose in a week. what could this mean and what can I do about it?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Brooke, You can have oil leaks but not see a drop where you park. There could be oil residue on the side of the block or under side of the vehicle that may not hit the ground, but pour out of the valve covers and "cake" on components. Make sure you are parked on level ground when you check the oil, wipe off the dipstick and reinsert in tube for sure accurate reading. DO NOT OVER FILL AJ Pierce

Suzanne Grego, Technician at City of Philadelphia Fleet Management Brooke, If you had an oil change, it*s possible the technician did not start the engine after the service and recheck the oil level. This will give an incorrect oil level reading. On most oil dipsticks, there is a cross section that is safe to drive the vehicle in and a full line that you should not go over. They may have just shorted you a half quart or so. You may want to fill it to the fill line and after a day or so, check it again. If it is low, you definitely are loosing oil somewhere. Make sure you do not overfill the oil - this will cause damage to your engine. You may want to bring the vehicle back to the place you had the oil changed and have them fill the oil to the correct level. Suzanne
