Yes, the type of engine oil you use can affect oil pressure. This is one of the main reasons why vehicle manufacturers recommend a specific oil type for your vehicle. If you have too much viscosity, your engine will struggle to move the oil throughout all the different passages, and this will raise the oil pressure.
Is high engine oil pressure a bad thing?
Similarly, engine oil pressure that’s too high is also a bad thing. The pressure increases as the engine oil encounter obstacles, which is otherwise normal. Nevertheless, too high of a pressure can lead to the oil flowing or skipping past narrower galleries. For instance, the bores or tiny openings for the oil to flow through.
Why is my oil pressure so high?

What does high oil pressure mean?
High oil pressure indicates that the rate of oil flow is being restricted somehow. This can be a result of a blockage, a faulty part, or even the oil itself. As previously noted, the ideal pressure should lay between 25 and 65 psi.
What does it mean when the pressure is too high?
When the pressure exceeds this range, this means that something is wrong, and it needs to be corrected before damage occurs to the system. Adequate lubrication is imperative to the health of any engine on any motor operated mechanism. Without proper lubrication friction can build, and you run the risk of overheating.
What is oil pressure unit?
The oil pressure unit is what controls the gauge in the dash of your vehicle. If this is faulty you will get false readings, the only way to check in this case for a failure is to manually check the oil pressure yourself.
What is the difference between oil grade and viscosity?
Motor oil comes in varying levels of viscosity, these refer to how thick it is and how much it weighs. The thinner the oil is the easier it will flow through the system. The thicker it is , the more pressure it will require to circulate.
What is an oil pressure relief valve?
The oil pressure relief valve is made up of three parts, a piston, a spring, and also a plug. Under normal conditions this valve is fully extended, and regulates the flow of oil. As pressure begins to accumulate, it forces the piston against the spring, which in turn allows more to pass through, in turn this decreases pressure.
How many revs per minute for oil pressure gauge?
Next, you need to connect the pressure gauge, turn the car on, and press the gas pedal, hold it between 2,500 to 4,000 revs per minute for up to 20 seconds.
Why does oil thicken?
As you probably know, the thicker your oil is the more pressure it will require to circulate through the system. It will also pick up more contaminants and particles, which will cause it to thicken, as well as increasing the wear on your engine.
Why is oil pressure so high?
As mentioned previously, one of the main reasons behind high oil pressure is the restriction of the flow of oil. This may be due to a blockage, which is a serious concern. This usually results from a buildup of sludge or a carbon deposit somewhere along the oil passage.
What does high oil pressure mean?
High oil pressure means that the flow of oil is being restricted in some way. This can be a result of either a blockage, a faulty part, or an issue with the oil itself. As we mentioned earlier, the typical pressure range lies between 25 and 65 PSI.
Why does oil thicken as it ages?
As oil ages, it begins to break down and thicken. As you know, the thicker your oil is, the more pressure it requires to circulate through the system. It also picks up more contaminants, such as dirt, dust, or metal shavings, causing it to thicken, as well as increasing wear on your engine.
What is the purpose of oil filter?
Oil Filter. As oil circulates throughout the system, it picks up harmful contaminants like dirt, dust, and metal flakes. This is where the oil filter comes in. As oil passes through (under pressure), any unwanted particles, do not .
What is oil pressure relief valve?
The oil pressure relief valve consists of three parts, a piston, a spring, and a plug. Under normal conditions, the valve is fully extended, regulating the flow of oil. As pressure builds, it forces the piston against the spring, allowing more to pass through, thus decreasing pressure.
What is the oil pressure sending unit?
The oil pressure sending unit is what controls the gauge in the dash of your vehicle. If it’s defective for one reason or another, you’ll receive false readings. The only way to check for this failure is to inspect the oil pressure manually.
What is an oil pump?
As its name suggests, an oil pump is in charge of “pumping” the oil throughout the system. This ensures that all the moving parts are well lubricated and do not create too much friction.
What does it mean when your oil pressure is too high?
This is especially true with high oil pressure, as it’s a good warning sign that there’s something very wrong with the pathways the oil needs to follow in order to properly lubricate the engine.
What is high oil pressure?
High oil pressure, as the name suggests, is when an obstruction or other issue causes the pressure needed to move oil around to rise.
Why does my engine seize?
Pressure helps move the oil through the narrow passageways in the engine, and a lack of lubrication can cause the engine to seize .
What is an oil change?
You’re probably familiar with this one. An oil change is a process through which old engine oil and dirty filters are removed and replaced with new oil and filters. This is an essential step to prevent engine damage with dirty oil and can help keep oil pressure levels reasonable.
How much oil pressure is needed for a car?
Every engine and vehicle has its own specific ideal operating range when it comes to oil pressure, but it’s usually somewhere between 25 ...
Why do engines need viscous oil?
Since engines are made from aluminum or another type of metal, there needs to be a viscous liquid to keep things from rubbing each other the wrong way. There are different oil grades and thicknesses for different types of vehicles and purposes.
Why does my oil filter slow down the flow?
As the oil flows through the system, it can carry debris, which then piles up and slows the flow, similar to how your thumb blocks the water flow from a hose. Other common causes include a dirty oil filter, which can happen if you don’t change your oil properly or if dust and other dirt build up over time.
What causes oil pressure to be high?
The major cause of high oil pressure is the stoppage of the smooth flow of oil. It can be the result of a blockade. It should not be taken easy. It may happen either when carbon is piled up in the oil passageway, or there is a sludge build-up.
Why do engines wear and tear?
Have a birds-eye view of the vital parts of the engine like pistons and valves, which always keep moving at high speed. The constant movement of parts causes wears and tears if they are not greased properly.
Does oil pressure rise?
No, it is certainly not. The pressure of the oil rises whenever a vehicle works harder. However, in case it fluctuates too much, there might be an issue with the sensor of your oil pressure.
Can you change the oil in a car that has high pressure?
The answer to that is a yes and a no. Changing the Oil can fix the issue in case the quality of the oil causes high pressure. But if the reason behind the rise of pressure is something else, changing the oil will be of no help.
Can you drive with high oil pressure?
Definitely not . Driving with high oil pressure can be a big risk as high oil pressure leads to engine damage. And to what could be riskier than driving with a damaged engine?. So, you should immediately stop your car and turn off the engine.
Can a pressure relief valve cause oil pressure to rise?
If the pressure relief valve is defective, it may cause oil pressure to rise though it is a rare occurrence. But still, there is a chance, so you must not take a risk.
Is it safe to start a car with low pressure?
Yes, it is completely fine. As mentioned earlier, the pressure goes up when the vehicle is working harder and vice versa. So, when you are just starting your vehicle, the pressure will be low, and slowly it will start to rise, and finally, it’ll settle in the middle.
What happens when oil pressure is too high?
So, when oil pressure gets too high, it can blow out seals and other components, leading to leaks and damage. Related: Causes of Oil in Spark Plug Wells.
Why is my oil pressure so high?
One of the most common causes of high oil pressure is a blocked, damaged, or clogged oil filter. While this typically only happens when your oil filter is particularly old, but it can happen if something comes up and hits your oil filter while driving. The good news is that if this is your problem, it’s a relatively easy fix – just complete an oil ...
Why is it important to diagnose and repair an engine with high oil pressure?
The higher the oil pressure, the faster damage will result. This is why it’s so important to diagnose and repair an engine with high oil pressure as soon as possible. Otherwise, you’ll end up with more expensive repairs and potentially need a whole new engine!
Why does my car have a pressure relief valve?
That’s why your vehicle’s engine has a pressure relief valve to direct oil when the pressure gets too high. But when this pressure relief valve is stuck closed, oil pressure will continue to rise without anywhere to go.
What happens if you have too much viscosity?
If you have too much viscosity, your engine will struggle to move the oil throughout all the different passages, and this will raise the oil pressure. Over time the engine oil will thicken further. This means that while everything might work just fine right after an oil change, over time the oil pressure can raise further and push outside ...
Why is it important to keep your engine oil in?
But as these channels constrict, the pressure it puts on the oil goes up. With too much pressure, various components can start to wear out and get damaged, which is why keeping your engine’s oil ...
Does oil pressure go back down when accelerating?
If oil pressure continues to rise when accelerating, doesn’t go back down, and increases outside of a standard range of operation, then you need to see a mechanic to determine what’s going on.
Why does overfilling the oil pan cause damage?
1) Engine Damage from Insufficient Lubrication. It seems wrong, but overfilling the engine oil actually leads to reduced lubrication between the moving parts. This happens because the crankshaft sits above the oil pan in most cars and rotates quickly as the car moves. If the engine oil level is high enough to touch the crankshaft, ...
What happens if you put oil on spark plugs?
3) Spark Plug Fouling. Excess oil can leak out and contact the spark plugs. Once oil coats the plugs, they may no longer receive the high voltage pulse that initiates the spark or the spark might not be able to jump the gap to initiate combustion. Fouled spark plugs can lead to engine misfires, running rough, or the vehicle may not even start.
What happens when crankshaft oil is whipped?
When the crankshaft whips the oil, it introduces air into the oil which makes the volume and thus the pressure in the system increase. Gaskets and seals are designed to hold a certain pressure of oil back from areas it’s not supposed to go, so over pressurizing it means that those are likely to give way.
How does an oil pump work?
Upon ignition, the oil pump switches on and sucks the oil up to start it circulating in order to lubricate all those moving parts. As the oil moves it passes through an oil filter , which collects any contaminants such as metal shavings that get picked up along the way. It is critical to have the right amount of oil.
How long should I wait to check my oil level?
It’s best to check after driving for 5 to 10 minutes so that the car is warm and the oil has been circulating. The engine bay will have a dipstick you can pull out, wipe clean, reinsert, and pull out to check the level. If the oil level is between the “add” and “full” lines, then you can rule out overfilled oil as the cause ...
What does it mean when your dashboard oil gauge is full?
A dashboard oil gauge that swings back and forth between “add” and “full” may indicate overfilled engine oil. The gauge is designed to work within normal operating conditions, so going outside of those can lead to a “confused” gauge.
How much oil should I add to my car?
Between the add and full line on the dipstick is usually about 0.5 to 1 liter. So if you need to add more oil, do so incrementally – about an eighth to a quarter liter at a time – to avoid overfilling.
Why is oil pressure so high?
The resistance the oil faces in flowing through a partially or completely obstructed passage could be one reason for high oil pressure. Relief valve malfunction: The purpose of a relief valve is to provide a place for the oil to flow when the pressure gets too high. Usually, these valves are set up to open and allow oil through once ...
What causes oil pressure to increase?
Over time, particles from dust, soot, rust, and gum get deposited in the filter and begin clogging the system . This leads to more resistance and higher oil pressure.
How to determine oil pressure?
Oil pressure is determined by the resistance oil faces when flowing through the oil passages of the engine. Oil pressure is indicated by the oil pressure gauge and should show a steady value around 20 minutes after engine start-up, when the oil has reached its operating temperature. The unit of measurement is either PSI or Bar.
What happens when the relief valve is malfunctioning?
If the relief valve experiences a malfunction, the oil pressure can quickly rise to a level that is not safe for the engine. Oil quality and viscosity: When oil is thicker (i.e: more viscous) it faces more resistance when passing through the engine's passages, leading to higher oil pressure. Changing the viscosity grade to a thicker ...
What does it mean when your PSI is over 80?
A PSI over 80 is usually considered too high for the engine to properly be protected from damage. High oil pressure is an indicator that the oil is not able to properly pass through the bores and reach all parts of the engine effectively. An engine that is not lubricated correctly can face (sometimes instant) wear through friction, ...
How long should I wait to check my oil pressure?
For this reason, it is recommended to wait 20 minutes after starting up the engine to gain an accurate PSI reading.
What factors affect oil pressure?
Since the oil pressure depends on how much resistance the oil faces when flowing through the passages, factors like the size of the engine, the diameter of the bores, and the viscosity of the oil have an impact on oil pressure.
