Q: Oil was leaking, put in over 4 qts of oil and oil leak stopper. White smoke coming tailpipe,engine shakes, car dies. Oil leaking.

asked by on

I put in some STP oil leak stopper and it said 4-5 qts of oil with it so I just kept filling it up with oil first then put in the oil leak stopper. When I tried to start the car it turned over and ran for a little bit but started shaking real bad and died. There's a lot of white smoke coming out of the back and the car shakes after I turn it on almost immediately then shakes violently and probably would die if I didn't turn it off. There's oil dripping from something attached to the engine on the left side and coming out pretty heavy.

Oil additives are not recommended by any vehicle manufacturer for any reason. Additives that purport to resolve oil leaks are useless, a waste of your money, and may result in engine damage. Every vehicle manufacturer strongly recommends against use of these materials. There is only one recommended and approved repair strategy when it comes to oil leaks: fix the leak.


You can only add the manufacturer specified amount of oil to an engine. If you add too much oil, or too little oil, that will cause engine damage. You should check the engine oil dipstick to determine if there is presently too much oil in the engine. If there is too much, the excess will have to be removed to prevent engine damage.


The leak that you are referring to can be repaired if you request an oil leak diagnostic. If you have further questions or concerns as you decide what to do, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you get the best possible results.
