I have to put oil in my engine approx every three months is this normal . I never had to do
this with any other car I have had . The vectra has low milage for an 04 and runs perfectly .
Any one got any knowledge of this
It's possible that you're burning oil or there could be a leak somewhere. Best thing to do is place a piece of cardboard under the vehicle overnight after the car has been driven, and see if there's any leaking happening. If not, then try to notice your exhaust. If it's coming out really white, then you may have an internal leak somewhere and it's burning off in the exhaust pipes. I hope this helps.
