Experts told what will happen if too much oil is poured into the engine

Motor oil is mandatory for the normal operation of the car engine. But what will happen if you pour it too much?

As told by the ampercar.com portal, the required engine capacity can be found out from the car's operating manual, or at a dealership or service center.

You can pour in excess oil without knowing - for example, not everyone takes into account that when it is replaced, about 10% of the old fluid remains in the engine. It is also possible to pour when the car is on a slight slope, or if it is poured when the power unit is hot. Or the hand may simply tremble.

If there is too much grease, it threatens trouble. The motor may begin to use it more than usual. The crankshaft can bubble the oil, which will cause it to foam. And this will cause the hydraulic elements to knock. Another unpleasant consequence is the leakage of oil seals. Through the front oil seal of the crankshaft, grease can get on the timing belt, as a result of which it will slip and wear out faster.

If the overflow of lubricant is constant, this may threaten the loss of mobility of the oil rings. Coking will occur, which will cause cylinder malfunctions, oil destruction, and exhaust gases entering the crankcase. The neutralizer may fail - as a result, engine power will decrease, an unpleasant smell will appear in the cabin, and fuel consumption will increase.

Oil seeping through worn piston rings or valves can leave a greasy residue on the spark plugs and damage them. Also, excesses can disrupt the operation of the turbocharger, causing deformation of the rotor shaft.
