Having problems with your 1996 Subaru Legacy ?
Mystry oil consuption,,no leaks - 1996 Subaru Legacy
Must be going out the tailpipe. Do a compression check on all cylinders and examine the spark plugs, Chances are you have a bad/broken piston ring.
You burning oil? Blowing it past the rings and out the exhaust? Oil can collect on the rings and burn and it can pass the rings and blow out the tailpipe with enough pressure (driving hard and fast a lot of the time like a street racer). If you are burning oil, your rings may be stuck allowing oil to collect on them. I've found that replacing conventional oil with thinner, synthetic will loosen the rings up making them seal better again and the thinner synthetic runs off the rings faster instead of collecting. Plus synthetic doesn't burn like dinosaur juice does. Easy fix to burning oil. Had it be the case on multiple older vehicles. No leaks, just burning. If you have a real old, loose engine all gummed up with dirt and oil all over the place, synthetic might expose/cause leaks due to how thin and slick it is. It doesn't carbonize like conventional oil and will help clean out voids the dino-juice gummed up. I've put it in a 1983 Toyota pickup with no problems. If the car is juck, be careful. If it's maintained fairly well and taken care of, give synthetic a shot. I stuck 5w-30 synthetic in a 1989 ford probe that asked for 10w-30 that burned a quart a month. Shortly after, no more oil loss. Hope this helps.
