When you accelerate, the engine's oil pressure increases because more oil is pumped through the engine to lubricate the moving parts. When you idle, the oil pressure decreases because less oil is pumped through the engine.
The normal oil pressure for a car is between 20 and 60 psi. If your oil pressure is too high or too low, it could indicate a problem with the engine.
If your oil pressure is too high, it could be a sign that the oil pump is malfunctioning or that the oil is too thick. If your oil pressure is too low, it could be a sign that the oil level is low or that the oil filter is clogged.
If you are concerned about your oil pressure, you should take your car to a mechanic to have it checked.
