Mercedes 1992 190E 2.6 Oil Pressure

I have a '92 Mercedes with 170,000 mi. on it. When I first begin to drive it during the day, the oil pressure reads 3. At all times: stopped, driving, speeding up, slowing down... . After the car warms up, I begin to notice that the pressure drops as I begin to slow down. When stopped at a traffic light, the pressure is all the way down to zero. I KNOW this CAN'T be good for the car. I've been putting it into neutral and rev ving the engine a little while stopped to at least have a little pressure.
What's the problem?! I've been told maybe the oil pressure sending unit...

Try or (have your mechanic) remove oil pressure switch and clean. They gum up and it's a safety feature that when car is in accident and/or roll over, when oil pressure drops (eng quits) power to fuel pump shuts off. Sticking oil pressure switch is common on Benz Diesels

Oil light is on


May be bad oil pressure sending unit. Best way to check is to connect a mechanical oil pressure guage to engine and check pressures when engine is warm. Should be no lower than 40 psi at idle when warm, no higher than 70 psi at 2000 rpm.

'Check gauges" light comes on and oil pressure gauge reads zero.


The first thing I would definitely do there is change the oil. Used oil tends to loose lubricity and becomes thinner than it was when in the container. When hot, it becomes even thinner and will cause a drop in pressure.
Most jeep engines hold around six quarts of oil, so by adding what you did the new oil helped a bit but cannot correct the problem.
I would change the oil and use either a 20w50 oil with a pint of Marvel oil, or change to a good synthetic with a container of Lucas additive. It is possible that whatever oil you have been using is causing a carbon buildup that is beginning to block off the pump pickup screen. Either of the above suggestions will help with that. In engine oils, price is important...cheaper oils are high paraffin base which causes deposits to form.
You don't want that in your engine. Only exception is Wal-mart store brand oil which I believe is Quaker State (re-packaged). If you opt for a synthetic, it's not a bad choice and is cheaper.
Make sure you use a good quality filter. The filter is what keeps the oil clean and useful during its lifespan.
One note... If there is any tapping or knocking inside the engine, that is caused by internal bearing wear and should be corrected immediately. No oil can compensate for internal pressure loss and if caught early, can be repaired. (otherwise, later, engine will need to come out and be overhauled or replaced.)
Any pressure problems can be verified by installing an external mechanical gauge on the engine. That is the only way to know exactly what is going on with any degree of accuracy. (dash gauge is electro-mechanical).
good luck

My check oil level light comes on, but the oil level is normal. 2007 mercedes c230


The oil light regards the oil pressure rather than the oil level. You may have low oil pressure or the sensor may have failed. You need to check the pressure in order to know what the problem is

1989 honda accord lxi fi oil light


Sounds like there is an oil pressure problem. Now this can be due to several factors. 1. low oil level in car
2. bad oil pump
3.bad oil pressure switch /sending unit
4. last but not least check oil filter and make sure its not clogged.
worn engine main/connecting rod bearings.
have pressure checked with a manual guage at oil pressure switch for the correct pressure. If that's good then the switch is bad and problem solved.
if it low then you will have to check pump and bearings. Contact if you need more help and thanks for using FIX YA

Fluctuating oil pressure on 92 Mercedes 300CE


Either the sending unit,(this unit is on the motor)is malfunctioning, or your engine oil pump may not be providing enough pressure.
This could be due to sticky oil pressure bypass valve,,worn out pump,,or worn engine main bearings.
If it is just a case of worn engine oil bearings,this is usually indicated by high oil pressure when cold,,but low oil pressure when hot,.i wouldn't worry to much, since most engines suffer from this same complaint and doesn't harm the engine any.

Oil Pressure Light


Chances are you do have low oil pressure, you should have a pressure check run with a mechanical test guage to verify the low oil pressure, for now assume the oil press is low, I wouldn't drive the car, you run the risk of damage to the engine bearings, a very very expensive thing to repair.
