Why Does the Car Jerk When Starting After an Oil Change?

[OliveDella]

Reasons for jerking when starting after an oil change: Engine Oil: The oil does not meet the standard or too much oil has been added. Generally, the oil level should be kept between the minimum and maximum marks on the dipstick. Try not to let it fall below the middle mark, as insufficient oil will reduce lubrication. A little above the middle is acceptable, but never exceed the upper limit on the dipstick. Otherwise, it will create unnecessary resistance to the crankshaft rotation, affecting power output and increasing fuel consumption. Break-in Period: After the break-in period of a new car, the engine noise may increase slightly, and fuel consumption will decrease. Viscosity: New oil has higher viscosity, which increases mechanical resistance and cylinder pressure.
