Last week my 2001 Grand Cherokee with a 4.7 was dropping below 10 and my "check gauges" light and chime came on. My sending unit was bad. I could see it was bad because oil was getting through the unit and leaking very slow. It's located above the oil filter. Easy fix, but the unit was over $50 and the 1 1/16 special deep socket for sending units was over $10.

As long as your warning light or alarm does not come on don't worry about it

I keep losing oil pressure when im at an idle but when i acc. the pressure comes back up and i have checked the oil it is fine


What is the make/model of the Jeep? What engine? Are you losing pressure completely or is it just low at idle? Many older Jeeps show little oil pressure at idle when the engine is warm. If you aren't hearing rattling like you are actually losing oil pressure, and the pressure comes up when you accelerate, you are probably OK.

Oil gauge reads 80psi what is the problem


Sounds like a faulty sending unit. Remove transducer (sending unit) and test pressure with external gauge. Hope this helps.

Oil pressure warning on 2001 Volvo v70 with 220Km


2 things i would do professionally first. 1. change the oil using a higher weight and a volvo oil filter(there is a difference) 2. have a "wet" gauge installed at the oil pressure sending unit to verify oil pressure from cold to warm. a "wet" gauge is a gauge that reads actuall oil pressure and not the use of electronics. it is usually very acurate. if the oilp pressure still drops, then you are looking at an oil pump issue most likely.

You better put a manual gauge on your engine and make sure you have oil pressure. Could just be a faulty gauge or sending unit but I sure as heck would be checking it with a manual gauge.

2002 jeep wrangler oil pressure gauge drops


When the gauge is at 0, is there any noise from the engine (tick, knock etc?) I would have someone put a mechanical gauge on there and read true pressure.Your driving pressure seems OK but if the low number is "real" something is wrong!

could be a worn oil pump or pump pressure relieve valve try finding a product called lucas oil stabiliers and use a full bottle with your next oil change should help bring the pressure back up and it will help you engine plenty

You need to verify the real oil pressure with a good oil pressure gauge. These are pretty simple gizmoes with a gauge and a hose. Get a hold of one and it screws in where the pressure sender is connected. Most engines need around 45 psi at idle. If it's not OK look for diluted oil, wrong viscosity oil or worse yet worn engine bearing or oil pump.
