Hey Rino==It shold be about 6#-15# at idle and 25#-45# at 55 mph. This is approxamate as the gauges on cars are not REAL accurate. If the factory put in gauges that were very precise, the price would have to go up another $500. If your oil preasure is much different than I have specified, have a manual gauge installed at least temporarily to see how accurate your gauges are. GoodluckJoe

What is the ideal oil pressure reading for a Buick LaSabre with a V6 engine?

There is no ideal pressure. Of course the oil pressure will be higher when the engine is cold. After it is running and at full operating temp, the pressure should read at least 10 lbs while idling. The pressure will be directly related to how many miles are on the engine and the amount of wear. A new engine will have around 40 lbs when hot and running at 2,000 rpms, and around 30 lbs at idle.

Why does 1994 Buick Lesabre oil pressure gauge go up and down?

The oil pump supplies the oil to the engine bearings where it is forced from one to the other. That is what creates the oil pressure. The pressure is transmitted to the gauge by way of a sending unit. You need a mechanical gauge to see what the true pressure is so as to determine if the sending unit is bad. A defective oil filter relief valve will cause a pressure fluctuation. The pressure will increase from an idle as you accelerate. You will need to check and see what normal operating pressure is and at what RPM.
