check oil question?

Question

yea i got a 1990 mustang. i check the oil 1st thing in the moing be 4 i leave, and it reads full. then, u start it and leave it run for a min, shut it off then check it again, reads a quart low. so, i add a quart, then its fine for 3 days of driving, goes down another quart low from full. the oil seems to go somewhere. no leaks, visable smoke or anything, where can the oil go? changed it 3 weeks ago and its allready pitch blk... whats wrong? runs rich.. could that be y?

Answer 1

The oil is in the motor but it gets traped in the top of the motor. the engine is gummed up from lack of oil changes..Change the oil every 1500-2000 miles till it gets cleaner. Also get the richness fixed it can be washing out the rings and can cause serious damage along with burning the oil because the fuel thins the oil....

Answer 2

Chances are the oil return holes are clogged in the cylinder heads trapping the oil in the upper portion of your engine. As you drive your car, if the oil is trapped, it will seep down the valve guide and burn through the combustion chamber, the oil that burns is so minimal that you never see the smoke, but over time can generate up to a quart of oil or more.

Answer 3

If your going to change your oil, use Gunk Engine Flush. The stuff really cleans the goop and sludge out of an engine. It's an easy 5 min process. Oh, and check your oil on a cold engine, don't start it, stop and check.

hi there, my x-husband is a car doctor lol. 1st of all mustangs are nice cars but every one know stangs burns oil. its getting colder out there so start useing a thicker oil and change it befor you add it. i hope this helps. If the car is burning rich you can change the jets in the carbonator. Hope this helps god Bless Ciao

Answer 5

There only two other places for engine oil to go, if it's not leaking externally, either the valve seals or the piston rings.
