Check oil,Very different readings when engine cold, and at running temp. Which is correct?

1 Answer

When an engine is cold,the first 5 min,the oil is thicker and you get a higher pressure reading

There isn't, a which is correct

You could have a bad sending unit, and thus inaccurate readings or engine wear causing it to drop off.

If your asking about different dip stick readings,then you only check your oil in the morning when all drained down and cold. Everyone knows that!

At running temp it should be the same,if you wait until it drains down,say a half hour

Also temp gauge stays low - would open thermostat trigger management light?


You bet. Engine running too cold makes computer think you need rich fuel mix (think choke on old school carb systems). Modern injected engines must run at correct temp. Note: if engine is really warming up normally but gauge is wrong that's a whole different deal.

The oil pressure jumps up to the max when I give it the gas right now. Could that be because its 20 degress outside or should I get it checked.


It is related to the outside temp and the cold temp of the oil. Cold engines with cold oil will read a higher pressure. The pressure should go down to normal when operating temp is reached.

My oil pressure guage is at the upper safe limit when at idle and tops out when I am moving. Is this a guage issue or a mechanical issue requiring immediate repair?


It could be a bad gauge or a check valve could be stuck or blocked causing your oil pressure to be too high. Have your oil pressure checked at a shop.

Heater will not get warm even after running engine it will heat when the weather is warm but when temp drops and it is cold it will not heatchanged thermostat, checked hoses,


did you install correct temperature thermostat? also is the temp guage in the car working and what does it read, if it reads a normal reading then the fan may be working improperly.

Hi,I have a 1998 bmw 328 sport and need to know how much oil is required to fill the engine from empty(do an oil service) and also how to top up auto gearbox oil?


fill engine on flat surface, then read the dipstick.

Transmission: raise car. Run car to normal oper temp. while running unscrew top access trans fill screw. nothing should come out. fill it till it does....it is now full.

For dummies: No, there's no trans dip stick. No, unscrew the top access plug while cold and not running....most of it will drain out.

For flat out stupid people, those with an IQ of room temp on a cold day: Take it to jiffy lube so the car doesn't fall on your head and crush it.

How do I check and possibly replace the engine oil pressure sensor in a 2006 GMC Envoy Denali?


Oil Pressure Test Check for proper oil pressure at the sending unit passage with an externally mounted mechanical oil pressure gauge. A tachometer may also be needed, as some specifications may require running the engine at a specific RPM.
  1. While the engine is cold, locate and remove the oil pressure sending unit.
  2. Following the manufacturer's instructions, connect a mechanical oil pressure gauge and, if necessary, a tachometer to the engine.
  3. Start the engine and allow it to idle.
  4. Note and record the oil pressure reading when the engine is cold. The engine may need to run at a specified RPM, if so check the vehicle's specification.
  5. Run the engine until normal operating temperature is reached.
  6. Check the oil pressure reading again with the engine hot and record the value. Turn off the engine.
Compare the hot oil pressure reading to the specification. If the reading is low, check the cold pressure reading against the specification. If the cold pressure is well above the specification, and the hot reading was lower than the specification, the engine may have the wrong viscosity oil. Change the oil, making sure to use the proper grade and quantity, and then repeat the test.
Low oil pressure readings could be attributed to internal component wear, pump related problems, a low oil level, or oil viscosity that is too low. High oil pressure readings could be caused by an overfilled crankcase, too high of an oil viscosity or a faulty pressure relief valve.

Where is the oil pressure sensor located on a 1996 murcury cougar


Look for the oil pressure sending unit on the block or the cylinder head on the V-6 or V-8 models. --- OIL PRESSURE TEST Check for proper oil pressure at the sending unit passage with an externally mounted mechanical oil pressure gauge (as opposed to relying on a factory installed dash-mounted gauge). A tachometer may also be needed, as some specifications may require running the engine at a specific rpm.
  1. With the engine cold, locate and remove the oil pressure sending unit.
  2. Following the manufacturer's instructions, connect a mechanical oil pressure gauge and, if necessary, a tachometer to the engine.
  3. Start the engine and allow it to idle.
  4. Check the oil pressure reading when cold and record the number. You may need to run the engine at a specified rpm, so check the specifications.
  5. Run the engine until normal operating temperature is reached (upper radiator hose will feel warm).
  6. Check the oil pressure reading again with the engine hot and record the number. Turn the engine OFF.
  7. Compare your hot oil pressure reading to specification. If the reading is low, check the cold pressure reading against the chart. If the cold pressure is well above the specification, and the hot reading was lower than the specification, you may have the wrong viscosity oil in the engine. Change the oil, making sure to use the proper grade and quantity, then repeat the test. Low oil pressure readings could be attributed to internal component wear, pump related problems, a low oil level, or oil viscosity that is too low. High oil pressure readings could be caused by an overfilled crankcase, too high of an oil viscosity or a faulty pressure relief valve.

MY SATURN 1 SHOWS NO OIL WHEN IT IS COLD BUT WHEN CAR IS TURNED ON IT SHOWS FULL WHY IS THIS


To check engine oil level engine needs to be off, if check while engine running, oil will splash inside oil pan and all over your dip stick giving you bad reading, Check oil level with engine off and add to full mark on oil dip stick. Running engine with low oil will cause major damage to your engine. To check transmission level engine needs to be running at normal engine temp.

95 toyota camery smells like overheating or oil burning even when engine is cold


Check radiator fluid level. Electric temp gages do not read temp unless there is water present, no water no hot temp reading.

Astro Van is running rough


No,the oil ratings 10w30 and so refer to how the oil viscosity reacts to hot and cold.As far as running rough,when was the last time is was tuned up,cap and rotor if applicable,spark plugs and air filter?Is it carburated or EFI?
