3 months ago we purchased a 1996 Subaru Legacy GT used with about 150k miles. The car is burning oil at an extremely fast pace...over a quart every two weeks. There is a tiny oil drop on the ground below the car and that'sit. What is causing the oil to burn so fast?

Have you checked the oil,checked to see if dipstick and fuel cap are tight.Do you have oil spots on driveway? Those are the first things I would check,if oil is on driveway is it coming from the oil pan.It 'seems" it May be tied in with the oil change from 2 weeks ago
the smell could be oil leaking on to the exhaust from the rocker covers.(common problem in Subaru because of the side mounted pistons. Engine stop oil leak might fix other wise will have to get tappet cover seals replaced as they crack over time from the heat) easy enough fix. a tell tale sign is signs of engine oil stains or signs of oil dripping on to the exhaust(can locate by looking under the front of the car at the bottom of the engine itself) and this is probably the cause of the engine knock due to low oil.it will continue to leak till the problem is fixed
WHITE smoke? Or BLUE smoke? White smoke is usually caused by burning antifreeze (possible blown head gasket). Engine oil burning causes a bluish colored smoke.
Changing the oil two months ago means absolutely nothing to me. I have customers that travel 6000 miles or more in a month. Oil consumption is measured in volume over miles, not volume over months. It is normal for most 4 cylinder engines to use a little less than 1/2 quart in 1000 miles (even more than that for 6 cylinder and 8 cylinder engines).
hi if its using oil and its not leaking, it has to be burning it or seeping through to the water via a worn head gasket, check the water for any signs of oil and other way round. Then check for smoke from exaust as i know these motors can burn rings out really fast in some cases if thats the case it will need new rings
the oil sensors tell you lots of things so yes it could be because you're burning up the oil. i would try putting in a bottle of Lucas it is thick and it should help you burn less oil. it is a full quart so don't over fill.
A V8 engine will start to consume more oil as they get more and more miles on them. The valve stem seals and piston rings wear, and let
more and more oil burn off in the exhaust. How many miles are you
travelling in said 3 weeks?
The ticking lifter on the Loyale is a common problem. There's a small o-ring between the cam tower and the head that, after so many hundreds of thousands of miles, would "fail" (not to a dangerous point) and the lifters would be partially starved of oil. It's not THAT serious... they can go hundreds of thousands of more miles like that. If you replace that o-ring, replace it with a spring reinforced ring so it doesn't fail. Those can be found at wwwdotthepartsbindotcom. As for the Legacy... those early 2.5s were cruddy. I've seen alot of them throw rods, lock up WAY before they should have. Best bet would be to replace it with a slightly underpowered but bullet-proof early model Legacy EJ22 or go with a newer EJ25. I would just go with the 2.2L.
