Can to much oil cause your car engine to go out?

Too much oil in the crankcase causes the counterweights on the crankshaft to whip the oil into an air filled milkshake foam.


Any time the foamy oil is pumped to the bearings (mains, rods camshaft and lifters) the lubrication is very poor at best.


More than a quart over the fill line can spell disaster in any car or truck motor.Can to much oil cause your car engine to go out?
too much oil can make you car quit running. Too much oil makes the crankshaft splash too much oil on the cylinder walls bringing it up to where the spark plug gets fouled out therfore cannot make a spark to keep the engine running or let it start. A telltale sign of too much oil would be a mass of blue smoke when you car was running. To solve the problem you will have to take out the extra oil by draining some out and then you will have to take the spark plugs out and clean them so they will fire again properly.
