SOURCE: low oil pressure 93 GMC P/U w/350 motor w/205,000 miles gauge

While engine is running, open the cover where you add oil to engine and see if you see a good flow of oil, if good flow, could be as easy as replacing oil sending sensor. got to realize that if poor maintenance history your engine may not be building enough pressure at iddle to move your hydraulic operated valves, only when you rev it up it will pump enough to run smooth. if running engine too long, you may cause more damage to other engine components such as crankshaft and cam shaft bearings. if you can spare a few bucks, have a good mechanic check your oil pressure with a mechanical gauge. another cheap option is to replace oil pump. last resort if you love your truck as much as we do,replace engine or rebuild it. At 205,000 this is a normal symptom, other than timing chain problems, most engines don't make it that far. hope this helps!

What causes Low Oil Pressure Light ?


Low oil pressure light is usually a bad oil sending unit. Make sure the oil level is full on the oil dip stick. Don't drive it low on oil because the problems could be severe...blown motor!

Oil Pressure Problem


Suggest you find a garage/auto repair who will remove the oil pressure sending unit on the motor and insert a oil pressure gauge and read the pressure.
Sounds like you have either a bad sending unit or maybe a plugged up oil filter. You are changing your motor oil every several thousand miles, right?
Be blessed.

Oil light on with plenty of oil on dip stick


Not only does the Oil light come on when it is low, it will also come on when the PRESSURE IS LOW or if the Pressure Sending Unit has gone bad or is DIRTY.

a. If you keep driving it, you can blow the motor if it is low oil pressure.
b. If it is low pressure, it could be due to blockage of passages or worn parts.
c. You can add Diesel Fuel (1.3 quarts to your Oil, do not drive it but let it idle for 15 mins... Drain the Oil and add a thicker oil (20w-50) and see if the light goes out.
d. Put a Gauge on the Engine and check the Oil Pressure. If it is low, and the oil increase to 20W-50 or 40 weight does not help... you are looking at pulling the engine.
e. If the Pressure is normal, I would replace the Oil Pressure Sending unit.

Good Luck

Oil gauge drops low at idle


Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

I have a 2007 chevy silverado. It was low on oil. I put 2 quarts in, oil light went off. When I drove it the low oil pressure light came on and also said engine shut down. What could be causing this...


If its reading low oil pressure I would first change your oil and filter.A clogged oil filter will cause your oil pressure to drop.Also remove your pressure sending unit and hook up a direct oil pressure guage to see what your actual pressure is.Its very possible that your oil pump could be bad.Those would be the most probable reasons for low oil pressure.The engine shut down means that your your engine has a fail safe to protect your motor from blowing up.

No oil pressure at idle once motor warm


Re-new the engine oil and see if the problem persists.
Low oil pressure at idle is usually a sign of a worn motor - worn camshaft and crank bearings allowing excessive oil to pass.
