Either the motor is in fact low on oil or the oil pressure sending unit is not working properly and may be producing a faulty reading. it sounds like in your case, the motor may in fact be low on oil given the fact that the motor is overheating.
Can a lack of oil cause a car to overheat? Low Oil. Motor oil helps to control the temperature of your car’s engine by minimizing friction. So, if your car is low on oil, possibly due to an oil leak, it can lead to engine overheating. Lack of lubrication causes friction, which will generate excessive heat, and potentially cause the engine to fail.
What are 10 common causes of overheating? Common reasons for overheating engines
Too little or no coolant. Driving without proper levels of coolant/antifreeze may cause a coolant system failure.
Cooling system leaks.
A broken water pump.
Radiator issues.
Oil too low.
Thermostat failure.
Issues with the belts and hoses.
Heater core is plugged up.

Can coolant affect your oil pressure?
It depends on what you mean and the vehicle. I have a vehicle with a chronic low oil pressure problem when hot. I have the coolant thermostat set at 180 or 185 simply to help keep the oil temps down. The lower the oil temps the higher the oil pressure.
How do I know if my Headgasket is blown?
How to Tell If You Have a Blown Head Gasket
External leaks of coolant from under the exhaust gasket.
Overheating under the hood.

Depleted coolant levels with no trace of leakage.
Bubble formations in the radiator and overflow compartment.
Milky discoloration of the oil.
Why is my car losing oil but no leak?
The engine must maintain a certain amount of oil to run efficiently and prevent engine destruction. If your car is losing oil but no leak or smoke, the problem is usually related to an internal oil leak that you don’t notice or important faulty components in your engine.
What are signs of a bad water pump?
Five Signs Your Water Pump Is Failing
Overheating. A dead or dying water pump cannot circulate coolant through your vehicle’s engine and, as such, the engine will overheat.
Coolant Leaks. Coolant leaks from the water pump are common and a clear sign that it’s time to replace the pump.
Corroded Water Pump.
Whining Noises.
How do you know if your thermostat is bad in your car?
Symptoms of a Bad or Failing Thermostat
Temperature gauge reading very high and engine overheating.
Temperature changing erratically.
Coolant leaks around the thermostat housing or under the vehicle.
How much does it cost to fix overheating car?
For most cars, some of the more expensive repairs to overcome the car running hot will cost between $500 and $1,500. These include replacing the water pump, radiator, or head gasket and changing the heater core cost. If you have a specialty engine or a diesel, these repairs may be even more expensive.
How do you diagnose an overheated engine?

How do you know if your engine is damaged without oil?
Here’s a list of some of the most common symptoms of low engine oil.
Oil Pressure Warning Light. The easiest way to tell if your vehicle is running low on oil is your vehicle’s warning light.
Burning Oil Smell.
Clunking Sound.
Less Efficient Performance.
Overheating Engine.
Will my car overheat if it needs oil?

Will a blown head gasket cause low oil pressure?
While the main effect of a bad head gasket on your engine oil will be water or antifreeze getting into your oil, a secondary result could be low oil pressure due to continued engine overheating.
Is it OK to drive with high oil pressure?
High engine oil pressure can cause severe engine damage such as oil pump drive and oil filter failure. Once these conditions occur the engine will rapidly start to wear and ultimately fail.
What can cause low oil pressure light to come on?
Common causes that trigger the illumination of the low oil pressure light include: Not enough or worn-out oil – Maintenance on any vehicle is key to keeping it on the road. Engine wear – Oil moves throughout the engine through the crankshaft bearing and the camshaft bearings.
What does a car sound like with a blown head gasket?
If the head gasket fails in such a way it allows the compressed air/fuel to escape, the compression of that cylinder is reduced. This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.
Is it worth fixing a blown head gasket?
A vehicle’s head gasket is worth fixing, so long as the vehicle was in good condition prior to head gasket failure. To help calculate if it’s worth fixing, follow this 3 step process: Determine the resale value of your vehicle if repaired. Get repair cost estimates.
Can you still drive a car with a blown head gasket?

How long can an engine run without oil before damage?
The presence of oil and its distribution is absolutely crucial to an engines continued operation. Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing – and in most cases, it’s a lot quicker than that.
What are the signs of worn piston rings?
When drivers notice excessive oil consumption, white or gray exhaust smoke, poor acceleration, and/or overall loss of power or poor engine performance, they may be seeing signs of worn piston rings.
