Is it bad for a car to burn 1 quart within 3000 miles before change oil?

And will the car fail the smog test for sure.Is it bad for a car to burn 1 quart within 3000 miles before change oil?
It's a bit more than I've experienced. It does indicate some wear but nothing out of the ordinary. The catalytic converter should be more than adequate to handle the excess. It might even be leaking a bit of that under load sometimes the engine will lose a bit of oil due to higher pressure so you may not be burning as much as you think. I wouldn't worry about it, if it really is bothering you have a compression test run on your engine.Is it bad for a car to burn 1 quart within 3000 miles before change oil?
1/3 qt per 1,000 miles is not an issue. Many motors consume more than that. MY LS-2: Pontiac says above 3,000 rpms the engine can consume oil so they get out of any warranty complaints. And GM also stated they are not going to pay any warranty clames for motors damaged due to lack of lubrication. Typically I drive hard and consume 1qt per 1,000 miles with no bad effect. The Cat converter cleans up any smoke and left over hydrocarbons.
have u changed brands of oil if so change back check air filter pcv valve make sure to use a quality oil if u dont add will it keep using i have seen vehicles that just like two burn off the top quart leave them a quart low they never go below that run them hard they will use for sure if u are pullin a load do u let it idle it will make ur oil dirty faster creates soot what weight are u using maybe try a heavier one
This is a point that you can find in some manufactured cars but not existed in other brands. I dont know why the cars that have this point dont try to enhance their engines to the same quality of other cars.





Generally maintain the coolent as overheating causes oil leakage.
is normal for a car to burn about a quart of oil about every 800 miles. they'res ways around the smog test.
