Oil Question

The motor will idle with 1.5 to 2.0 BAR oil pressure and peg at 3.0 while driving. The oil level on the dip stick should be BETWEEN the two notches or marks on the dip stick. Overfilling is bad so don't, the extra oil gets aerated by the spinning crankshaft and the tiny bubbles prevent full oil pressure from being achieved.

As to what kind of oil to buy see:

And buy an Owner's Manual; it will tell you a lot about the car. Dealer, or orwww.books4cars.com

The oil level can only be read off the dipstick with the car level and the engine shut off.

The oil gauge you are looking at is pressure only - it IS NOT an indicator of oil level. Pressure will vary with engine speed and cold start temperature. If the pressure goes to zero you have big problems.

You did not say the year of your car, but it should have an low oil level warning light on instrument cluster. Be sure the bulb is good by checking if it lights when you first turn the ignition on (yellow light with a small oil can on it). If that light starts to blink-on when braking or in a curve, it is certainly time to add oil. If it remains on constantly while driving, check the oil level at once. Do not depend on this light exclusively though, check the dipstick regularly.

Shouldn't the oil pressure gauge show max for anything above idle?

Once one is convinced that there is no leak then -- subject to extreme driving conditions -- it should not be necessary to add oil between the

6000-mile changes.
