Why does oil pressure drop when engine gets warm?
Oil pressure drops as engine gets warm. Increased clearances due to wear can cause pressure to bleed off faster with lower viscosity oil, leading to lower pressure on the gauge. More than anything, it could be some wear. It could also be some sludging or carboning of the oil pressure relief valve in the oil pump.
Why does my car have low oil pressure at idle?
Car owners often forget to check their engine oil level. If your engine is low on oil it can cause low engine oil pressure at idle because there won’t be a sufficient amount of oil to circulate and lubricate the engine. This can lead to serious engine damage due to lack of lubrication. I check my engine oil every 2 weeks.
Why is oil temperature important to your engine?
One of the things you will find if you have a oil pressure or temperature gauge is that regardless of the fact that oil is running through your engine and cooling it just like the coolant – it takes on and loses heat differently than coolant.
What happens if the oil temperature is too cold?
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. VTEC engines actually do not engage VTEC unless the coolant is up to temperature, for example – this is true of many other variable valve timing technologies as well.

What does it mean when your oil pressure is low?
Seeing a warning light come on indicating your engine has low oil pressure could mean you have a serious problem. Having the right oil, along with the correct level of oil and oil pressure is essential for an engine to run optimally. If the pressure drops too much, an engine can be damaged beyond repair in a matter of minutes.
How does viscosity of oil affect oil pressure?
Oil viscosity relates to how easily the oil flows around the engine at any given temperature. If the oil’s viscosity in your engine is wrong, it can register as low oil pressure. High viscosity oil will typically produce greater resistance, while low viscosity has the opposite effect.
