What should the oil pressure be on a Chevy Duramax?

Lb7 – 15w, 80lbs on start up at 20°. Then at temp about 30 according to the gauge. These are high volume low pressure pumps. Lb7 – 15w, 80lbs on start up at 20°. Then at temp about 30 according to the gauge. These are high volume low pressure pumps.

What should the oil pressure be when the engine is cold?

When the engine is cold at start up the pressure gauge reads 30PSI plus. After it warms up and at a stop in drive the pressure will drop to approx 5 PSI and will even dip to 1 or 2 PSI. Oil being used is 10W40. Idle is a little rough but not too bad. Engine does not burn oil.

What should the oil pressure be at idle?

It’s as high as 80 when the truck is cold. It’s borderline ridiculous how much the oil pressure fluctuates. I have seen as high as 98 psi at idle on a cold idle and as low as 23 psi on a hot one. Click to expand… Exactly.Same here. Its perfectly normal. Most manufacturers make it so the gauge doesn’t move to inspire confidence.

What causes an engine to lose oil pressure as it warms up?

The most likely cause of a car losing oil pressure when it warms up is a problem with the pressure relief valve, which regulates the oil pressure to ensure that there is enough pressure to circulate oil throughout the engine. When oil pressure is low, not enough oil is being distributed to the engine, potentially causing engine failure.

Is it normal to have low oil pressure when starting a car?

To a certain extent, it is normal for a car to have low oil pressure when first starting. However, within 20 minutes, the oil pressure should be regulated, and the needle on the oil pressure gauge should rest at the midpoint. If the oil pressure remains low, have the oil pressure relief valve inspected by a mechanic.

Where is the oil gauge on a GMC Truck?

Learned my lesson! Get a mechanical oil pressure gauge on there immediately. You don’t have to mount it in the dash, just hook it up and leave it hanging out of the hood or whatever…just do it. I don’t have a mech gauge but I’m bringing it down to my friends shop tomorrow to see what’s up.

Is the oil pressure on the Dodge LMM accurate?

The oil pressure gauge on the lmm is actually dead on accurate. The Dodge gauge is more like an idiot light. Itll be in the middle until you have no oil pressure then it’ll drop to zero. Think about it, its a pump that changes rpm with the engine, of course pressure will fluctuate. It does with all engines.

Is there an oil pressure gauge on a dumptruck?

Those were my exact words about a 1997 Ford 460 in a dumptruck. Then the engine had to be replaced. Learned my lesson! Get a mechanical oil pressure gauge on there immediately.

The Dodge gauge is more like an idiot light. Itll be in the middle until you have no oil pressure then it’ll drop to zero. Think about it, its a pump that changes rpm with the engine, of course pressure will fluctuate. It does with all engines. Its just a matter of how accurate the stock gauge is.
