What happens to an engine when the oil temperature is too low?
In all engines, the engine’s clearances are significantly tighter, creating extreme amounts of stress on the engine’s internals and the piston rings will not have properly sealed with oil temps too low. In short – it’s really bad for your engine to run it hard until it’s OIL is completely warmed up.
What should the oil temperature be after warming up?
As a general rule of thumb, after the car is warmed up, oil tends to be a few degrees warmer than the coolant (usually 10-15 degrees Fahrenheit).
What happens if your car engine is too cold?
However, it’s an extremely risky thing to do and can easily result in catastrophic engine failure. ESPECIALLY in highly tuned, built engines. If the engine is way too cold (ie, the coolant hasn’t even come up to temps), it’s not making its ideal power either.
Why is it important to keep your engine warm?
Remember, an engine fully warmed up but not heat soaked creates optimum power. In the real world, this means when you’re driving down the highway and the engine is plenty warm and the airflow through the engine bay is taking warm air from the engine bay out through the bottom of the car.

What should the oil temperature be when you start the car?
The oil temperature is a vital part to keeping your engine running smoothly. The oil temperature should be a few degrees warmer than the coolant. If the oil temperature is too high, problems can arise. When you first start your vehicle on cold mornings, let the car idle for about five minutes until the oil gets a chance to warm up.
What to do if your oil temperature is too high?
If the oil temperature is too high, problems can arise. When you first start your vehicle on cold mornings, let the car idle for about five minutes until the oil gets a chance to warm up. This way, your engine will run more efficiently and live much longer.
What to do if your oil temperature sensor does not move?
Gauge does not move. If the oil temperature sensor does not move at all, it has most likely failed and needs to be replaced by a professional. The mechanics at YourMechanic provide an oil temperature sensor replacement service that is affordable, and will have your gauge back to normal.
