Does Needing an Oil Change Affect Acceleration?

Over time, engine oil gets clogged up with dirt and debris. This can lead to engine lubrication issues. You might want to change your oil and see if it will affect acceleration and engine performance.

Do you notice a performance improvement after an oil-change?

A typical oil change will not affect the vehicle’s transmission or fuel injection. Oil flow can become restricted by dirt and other debris over time. If you have any questions, please contact us. dirt accumulates quickly in oilThis is a separate problem that could also be a cause. An oil change will improve the efficiency of your engine. Because the oil will be properly lubricated, the engine’s moving parts can benefit.

Many car owners report experiencing power and acceleration issues after an oil change. This could be caused by an improper oil change.

Why is my car struggling to accelerate suddenly?

Many mistakes can be made if you don’t properly change the oil. Acceleration problems can result from using the wrong oil, or adding too much oil.

Causes of loss of acceleration following oil change

1. Oil tank overfilled

It is likely that the oil tank was full during the oil change. Even a 1-quart increase in oil The crankshaft can be dipped into oil at a certain level. This allows the oil to aerate and results in foams and bubbles.

This could lead to engine acceleration and improper lubrication. Make sure you drain any excess oil beyond the dipstick’s MAX.

2. Incorrect viscosity oil

Proper engine lubrication requires the use of the right viscosity oil. High-viscosity oils are preferred for high-performance engines in hot climates. Engine acceleration problems can be caused by using the wrong viscosity oils.

For the best oil recommendation for your vehicle, consult your manual or your mechanic.

3. Take out the vacuum hose

The vacuum line is responsible for maintaining the engine pressure. The vacuum hose connects via a tube the manifold vacuum and the engine components. Most likely, the vacuum hose was cut during an oil change. This can cause engine problems and reduced power.

4. The old gasket must go

The oil filter filters out any foreign particles from the fuel. The oil filter must also be changed during an oil change. It is possible that you will still need to remove the old seal from the filter’s open end. This can cause an oil leak and the oil filter to not fit correctly. This will cause poor lubrication and lower engine acceleration.

5. Other concerns

  • It is common for people to drain transmission fluid rather than the old engine oils. The engine oil will then be filled to the top. This will reduce transmission performance and cause engine acceleration to be slower. 
  • The mechanic who changed the oil also changed something that could have an effect on the acceleration.


For proper engine performance and lubrication, it is crucial to change the engine oil. If you or your mechanic make an error during the oil change, you may experience acceleration problems in the engine. You could have an overfilled or incorrectly graded oil filter, improperly installed oil filters, or an inadvertently installed oil filter. It is best to have a mechanic examine your vehicle and make repairs.
