Is it normal for an engine to burn oil every 750 to 1000 miles?
Some manufactures seen to think it’s OK for their engine to burn a quart of oil every 750 to 1,000 miles. I can assure you that oil burning is not normal for any engine and is a smog concern according to the California resources board.
The oil burning you experience may not be seen when driving or sitting steal with the engine running. The amount of oil burned is very small but never the less it is using oil. Over time the oil usage will get worst as the miles increase.
The cost to repair an engine from burning oil is as much as a new vehicle, depending on which vehicle you have purchased.
I have inspected several vehicles with the V-6 and V-8 engine and they were using oil every 750 to 1,000 miles. The owners have complained to the dealership for the oil burning issue’s, and was told it is normal. This normally happens after they run an oil consumption test and can’t repair the engine unless it’s completely replaced.
The engine cost can be from several hundred or as much as $10,000.00, this is just for the parts and this does not included the labor to remove and then reinstall the new engine at labor cost starting at $85.00 an hour for as much as $150.00 an hour at most dealers, exotic cars may be much more.
I have also seen this oil burning concern with the 3.8 engine, this person was told it is normal for their engine to burn oil every 750 to 1,000 miles of driving; in fact it was in writing the engine will burn a quart of oil every 750 miles but was not true. The engine should not burn oil any time between oil changes on any engine.
I have also seen very high end vehicle costing over $80,000 dollars to buy and they are having problems using oil every 1,000 miles and the owner is told; the engine burning oil is normal for this engine because it has a Turbo. The replacement engine for the vehicle is over $30,000 dollars (yes over 30K) not to include the over 25 hours of labor at $135.00 to $150 per hour average cost to install it. You might want to think twice before investing in a vehicle that has this oil burning concerns.
What causes an engine to lose or burn or lose oil?
There are several things that will cause abnormal oil usage or burning,
1) Damaged or worn valve guides
2) Damaged or worn valve seals
3) Collapsed, broken or stuck piston rings
4) Damage pistons
5) Damage piston walls
6) Clogged breather valve
7) Oil leaking from seals and gaskets
Signs of oil burning are usually accompanied by Blue Smoke from the exhaust when it is started or running depending on what part is defective or damaged and how bad the damage is. Oil leaking can also contribute to excessive oil usage and this is something that will be seen after you park and let the vehicle sit awhile. Most oil leak repairs are fixed by replacing a seal or gasket.
If valve guides are worn blue smoke will be seen when the engine is started, usually after it has run and then sits awhile.
If valve seals are worn or broken blue smoke will be seen when the engine is started, usually after it has run and then sits awhile.
If the piston ring seize, break or collapse in their groove, oil will pass causing the excessive oil burning. Damaged pistons and rings will cause oil burning and excessive blow-by. This will also cause the exhaust smoke to be blue when driving or at idle depending on how bad the oil is leaking past the piston rings or valve guides or seals.
When an engine is using oil it is caused by defective piston, rings or valve parts and the engine will need to be removed and over hauled. It’s a time consuming job and very costly depending on the vehicle.
If you are told the oil burning is normal don’t accept that just because the dealership is telling you. In fact if you call an engine repair shop that rebuilds engine they will tell you when an engine is burning oil it will possible need to be overhauled, that means all intern parts will need to be cleaned and replaced as needed.
