Oil pressure gage fluctuates;red oil icon stays on; alarm bell keeps ringing. I added 2 qts of oil. no change.

Oil sending switch needs replaced.

The first thing any good technician would do about the oil pressure is remove the sending unit and hook up a mechanical test gage to see what the pressure is, GM oil pressure gages are famous for this very complaint, most likely the oil pressure sending unit is defective. As far as the other problems go it could be related.

More then likely the sending unit is faulty, but to be safe hook up a mechanical test gage at the oil pressure sender port and check oil pressure hot engine, if it is steady then replace the sending unit.

That is a good sign, it is working, my oil pressure fluctuates like a tachometer, at idle it is low, like 20 lbs, then when I 'm cruising, 35lbs, but it goes up and down when you pump the gas. The pressure gauge is reading the oil pressure at the top of the engine, it will show 45 lbs with only 1 qt of oil in there, it is not an oil level gauge. You might have an oil light buried on the dash somewhere that will light up if the oil gets too low. ,, Now about that coolant leak, it should have nothing to do with the oil pressure. Is it a hose? Radiator? Joint at the top of the engine? Where is it leaking, and what is it doing? Does it over heat? Or did it overheat? Is there oil floating at the top of the radiator? Does it blow steam out the exhaust? Does it have coolant or just water? Check it out. hope this helps.

The oil pressure alarm is very important, the last thing you want to do is dasable it, need to check the oil level, if it is full then it would be wise to take it to the shop, probably a malfunctioning oil pressure sender

If your oil gauge if you have one reads good pressure, more then likely you have a bad sensor, if you just have an oil light, take it to a repair shop where they can do an oil pressure test. Have it check, low oil pressure can cause major engine damage.

All you have to do is replace your oil pressure sending unit.It`s in the rear of the motor by the left head.This is the drivers side.You need a special socket to remove the sending unit.Good luck.

Two quarts is about half the capacity. The pump was probably starved of lubrication and is failing.

If that's not expensive enough, you may now have a problem with a damaged engine. You may want to just put that money into a new vehicle.

I don't think the car would have enough power in its present condition to get high enough to reach a cliff, and driving it into a lake would not be environmentally sound. Besides, the fine would not be worth it.

The cheapest and easiest maintainance that anyone can do on a car to avoid expensive repairs is still checking the oil ever 1000 miles (filling if necessary!) and changing it every 3000.

could be that the screen in the oil pan where the oil is taken up is clogged. not certain--maybe oil change?

Hi! The problem you are outlining is very similar to the Rover V8 (Buick engine). We Brit's are used to the low oil pressure when warm. I presume a complete oil change engine flushed with new replacement filter has been carried out? Maybe a top quality synthetic oil with additive may help. You may take it a little further and replace the oil pump with an after market performance up rated one. If you really are worried about low oil pressure damage whilst in low rev's try Molybnenum Disulphide an oil additive which really reduces friction metal to metal wear particulary in the situation you are describing.
That's the best I can suggest at this moment.
Good Luck! and Happy New Year!
