I get my oil changed every 3 mo. I am loosing oil but nothing on the ground. What are the possibilities that it could be? I have 117,000 miles and the van is in otherwise great condition. -
Answer 1
i would bring it to a shop that perform test to find out your oil leak and maybe compression test also. -
Answer 2
any smoke from the exhaust? is the air filter oily? -
Answer 3
Valve cover gasket(s) or other , leaking onto exhaust and burning off before it hits the ground? Any smoke on first start-up? How many miles in 3 mos.? Proper viscosity oil being used? -
Answer 4
How many miles are you driving in those two months? The oil is probably being burned by the engine. This is normal. You add oil as necessary. -
