burning oil

Hello all,

I have a 98 f250 ld 4.6l 4x4 ext cab. I am losing oil somewhere no smoke or leaks. I was wondering what it could be and also should i do any additive like sea foam or lucas?

Please help.

How much do you lose per 1000 miles?
There can be several causes of oil loss.
1. Intake valve stem seals.
2. PCV valve stuck open.
3. Gasket leaks.
4. Ring seal.
5. Gasket failure in the oil supply tract from block to heads, on rear pass side or front driver side.
6. Pan gasket/crank seals etc.
Good luck.

Oil additives are snake oil in my opinion. If you are running the right oil for your motor, you shouldn't need anything else.

How many miles are on the motor? And how much oil are you losing?

How fast are you losing oil? 1 quart per ? miles. Does it drop one quart low and stop dropping?

More info = better advise.

OK, the light comes on for low pressure, not low level. So you have a pressure problem.

You may want to try to rename this thread, or maybe start a new one with a better title. That way people who have experienced your problem and solved it will chime in with what to look for.

So how many miles since last oil change?
