Why Does My Oil Pressure Go Up When I Accelerate?

The performance of oil pressure and engine functionality goes hand in hand. If oil pressure is odd, the flow will get impacted and it won’t reach all the parts. It results in malfunctioning, lack of lubrication, and damage to your car!

In simpler words, oil pressure in a car is checked by the resistance that the fluid (oil) flow has to experience during flowing from the oil passage in the engine. This pressure is clearly seen on the oil pressure gauge and must always be steady, around the around 20 minutes after engine start-up.

Oil pressure gauge keeps you aware of engine performance in case of oil pump failure, broken hose, or a leaking gasket etc. In this article we will discuss why oil pressure goes up when you accelerate, and what you should do after that.

High Oil Pressure Gauge

In cars, the oil pressure gauge is the indicator on the dashboard that tells you about its performance. High oil pressure means oil simply means oil in the car is not working ideally as it should due to not being able to pass through the bores.

It can cause problems reaching the other engine parts; which is certainly a concern. As you know the oil pressure is maintained via the oil pump through the engine of the car, so it’s important that it always receives smoothness and lubrication.

Ideal Range of Oil Pressure

Ideally, the oil pressure gauge should be between 20 to 30 PSI for cars and 25-35 PSI for trucks. You should check your car’s manual to know the specific engine requirement for best oil pressure level.

Oil pressure should be around 30 PSI when running idle and about 60 PSI when the engine is running at higher speeds. But if it’s lower than 20 PSI, get your car repaired and maintained.

Beyond recommended range, there are chances of friction, overheating, and excessive wearing of the engine. Conversely, the high oil pressure in the engine puts strain on the component which is likely to cause fault, malfunction or permanent failure.

Oil Pressure Go Up When I Accelerate- Causes

The hike in oil pressure when you accelerate a car is normal. So, if you see the fluctuating oil pressure while you drive your vehicle, don’t panic. There are quite some reasons for that. For example due to engine temperature, speed, oil viscosity, etc. pressure oil increases because motor intensify its job.

When the oil is either thick or cold, the oil pressure gauge will likely decrease, provided the engine is not working. But if the oil pressure regulator moves or lies completely to the lower level it could be due to oil filter problems or oil pump problems. Top reasons for oil pressure going up are;

  • If the oil pump is faulty
  • If the engine is overheating
  • If the pressure relief valve is
  • If the bearings are damaged or faulty
  • If there is blockage or sludge or other deposit buildups
  • If you’re using components or parts that are not designed for your vehicle

4 Signs of High Oil Pressure

There are few common signs to tell you what’s causing high oil pressure in your car. Here are the common signs/symptoms of high oil pressure here.

1. Oil Leaks

Oil leakage is the main culprit for engine malfunctioning. Usually, high pressure of oil will cause the seals to come off and other components will likely to blow out as well. It will cause oil leakage which leads to high oil pressure.

2. Malfunctioning Engine

If the engine is not working properly, it can lead to an oil pressure hike. The reduced oil invites friction and friction causes heat and damage to the components. If you don’t address the issue timely, it will cause serious engine damage.

3. Overheating Engine

Another sign of high oil pressure reading is when the engine is overheating. While engine overheating has many reasons, a hike in oil pressure is amongst them. High oil pressure causes improper oil flow to the engine and the lack of lubrication causes friction. This friction between components causes overheating.

4. High Oil Pressure Reading (Gauge)

High oil pressure is certainly the obvious sign to determine if your vehicle is having poor oil pressure reading. Some cars/vehicles don’t have oil pressure gauge but most of them have the indicator. So if you see high oil pressure when accelerating you need to turn your car to the repair center.

FAQs

Is it normal to hike-up the oil pressure when I accelerate?

It is completely normal for the oil pressure to go up when you accelerate the car. However, if you see any changes in the car performance during that time, it can be an indication of something.

For example, when you notice strange sounds such as ticking noises or engine knocking it can be due to a faulty oil pump or oil pressure sensor. Sometimes it can be due to poor engine components. If you spot any odd noises from the engine, it’s time to get it to the car mechanic as soon as possible.

What are the consequences of high oil pressure?

High oil pressure implies insufficient supply to the engine oil pump due to some reasons. If you don’t take care of its solution, the consequence will be engine failure, overheating and potential damage. When oil does pass through correctly, the lack of lubrication can even cause permanent component or engine damage.

Is it important to seek professional help for high oil pressure?

Regular maintenance of your vehicles is always very important. That said, seeking “professional” help is more highlighted.as you know oil pressure in a car makes sure the proper functionality of the engine and related parts, therefore make sure the gauge reads the recommended level (mentioned above).

What is Oil Pump in Cars for?

As the name suggests, the oil pump in the car is there to pump the oil in the engine to keep flowing ideally. Oil pump is the internal combustion engine component/part that makes sure to circulate the oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine.

Conclusion

Oil pressure in cars must be at recommended levels. However, if you see odd behavior of your vehicles, it is always important to rush to the mechanic rather than assuming things on your own. Each car model has its specified oil pressure recommended range which you can know from cars manual.

Addressing the issue early always saves you from unavoidable car damage and expensive replacement of its parts. Not to mention how  maintained oil pressure adds to longevity and performance of your vehicle.
