So i added about a quart check later its dry again, This morning i decided to check it again its dry, so i add a Quart, Can anybody help me out or those who have expericanced this issue. Thanks

Have you noticed any spots on the pavement or driveway where your car has been sitting? If so, are the spots towards the front of the car or more towards the rear?

if your car was burning that much oil you would definately see it coming out the exhaust. Pull and inspect all of your plugs along with your exhaust. Check antifreeze as well

There are no Spots, Also i replaced the plugs 1 k ago, i do think that one of my cylinders are misfiring and a ignition coil is about to go, because espically in high gears the car shakes , and during normal acceleration its not smooth its choppy .The oil issue is weird tho, what about the antifreeze i should check?

you want to check your coolant for signs of oil....

it is most likely a plug that is getting fouled

Hmmm... Is it full now ??

Having to add 2 quarts in 2000 miles is a bit much... You'd have a cloud of smoke behind you if it was burning that much...

How much oil did you put in when you changed the oil ??

Maybe the last time you changed your oil it accidentally drained out and now that you're adding new oil it's just filling the bottom of the pan? 2 qts on an almost empty oil pan probably won't fill it up enough to be seen and will continue to look dry when you check it. Try filling it all the way instead of putting in 1 qt and make sure it's full b4 you drive it. Either that or you have a mis gapped plug, or just a straight up bad one. You could also have a damaged piston or sleeve. Did the vibrations happen after you changed your plugs?

You're adding a lot of oil. I would guess that if you haven't noticed any smoke, then you have a leak some place. Check that out too.

There is no smoke , Also the vibrations were happening before the plug change... so Iam thinking a coil is dieng and the car is misfiring.

you'd geta code if you had misses..but i dont think that would have anything to do with eating oil...have you tried filling it (not just add a quart)

Who changed the oil last? Maybe they did in incorrectly. I'd do a new oil change with a new filter making sure it's filled to specs & then test it from there.
Also get under the car with a flashlight. Just cause it's not dripping doesn't mean it's not leaking.

That's my bet.

I will change the oil this weekend and check day by day to get accurate readings..
