What temperature should engine oil be?
A quality conventional motor oil will tolerate oil sump temperatures of up to 250 degrees, but starts breaking down over 275 degrees. The traditional approach is to try to hold oil temperatures between 230 and 260 degrees.
What temp does synthetic oil breakdown?
Superior temperature resistance. Synthetics can safely handle higher operating temperatures without oxidizing (burning) or breaking down. The upper limit for most mineral-based oils is about 250 to 300 degrees F. Synthetics can take up to 450 degrees F. or higher (some as much as 700 degrees F).
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 happens if your engine oil gets too hot?
This is especially true in turbocharged engines or on high speed circuits as engine oil can actually cook if it gets too hot, ruining it’s lubricating properties and resulting in – yep, engine failure. Remember, an engine fully warmed up but not heat soaked creates optimum power.
Why does my oil pressure go up when the oil is warm?
Many people do not realize that when your engine oil is cold, you normally have very high pressure. Mostly twice as high as when the engine is warm or even higher. Check your pressure when your engine oil is hot instead.
When to know if your oil pressure is high or low?
Before concluding that your car has a high oil pressure problem, it is a good idea to first check that the oil pressure gauge is working properly. If the car is on idle and the engine oil is hot – you normally have low pressure. If the engine oil is cold and you rev up your engine, the gauge should be much higher.
