Engine Oil Pressure Gauge

[Guest won]

Hi Guys! i believe there were questions asked previously about this issue but couldn't find it. Mine is at 3 when cold and on the move for about 15 mins. Thereafter, it will drop to 2.5 and sometimes maybe 2.2 when stopping at road junction. Is this normal? What is the recommended level? I read somewhere in the forum and someone mentioned that his car's gauge level was always maintained at 3. Anyway, mine is a '93 model W124, 16V.

my 95 masterpiece stills at 3.....

my fil 95 masterpiece varies....

now after his engine is overhauled and piston ring changed....

stays at 3.....

stable....

that is the thing i can tell u for now....

hope u can get more answers....

my mileage when i gotten my car 116k km....

my fil when gotten his car 168k km.....

but his was in a bad shape....

but now it is in very good shape....

:D

after spending close to 7k already!!!!

mine stays at 3 when at idling when the sensor is faulty. replaced and it is hovering ard 2 to 2.5

[Guest won]

Thanks Clarkewan and Mike. Can i know what's your rpm when idling? 700, 800 or 1000?

:punk1:

[Guest Mike]

air con off ard 650 air con on ard 750

[Guest clarkewan]

My throttle body also changed new one so now very stable for idle. I check n post.

[Guest Mike]

some dealer r adjusting the the throttle cable to make sure the car dun die off. it hides throttle boby problem. for those throttlebodies that have love idle problem

[Guest won]

I changed my throttle body too! very ex!

[Guest clarkewan]

after changing...

the car feels new...

stable...no unnecessary jerking...

:D

worth it still...

:D

less than 700$...

brand new siemens vdo throttle body with the computer thingy there....

[Guest Mike]

yup the price is ard there

[Guest mr w124]

computer thingy? is that the same for the 8v?

[Guest Mike]

8 valve is different from the 16 valve 1

[Guest clarkewan]

Oh yes, mine is the 95 model 16v.

The throttle body comes with a siemens vdo computer box.

8v is just a throttle body.

Mine is 92-model 8V. Same behaviour too - when moving it shows 3, but when stopped (especially when brake pedal depressed) it shows around 2.5... so is this normal?

[Guest clarkewan]

According to many mechanics, it is normal.

[Guest Mike]

it is very normal for the pressure gauge to drop whn the rpm is lower than 1000 but notdropping to the extend of reaching 1.5

[Guest clarkewan]

it should be between 2.5 to 3....

not below that....

[Guest Mike]

thinner oil will have a lesser reading

[Guest won]

That's interesting! Are you guys using synthetic oil?

[Guest clarkewan]

I recommend no syn oil but use good brand n regular service.

[Guest MBfallshirmjager]

Do you guys service on a 5000km basis or 10,000km basis huh? :la: Mine currently is on a 10,000km basis because the first service my W124 used synthetic oil. I am thinking once my car hit 10,000km to be due for servicing, I may switch to mineral oil and then send for regular service on a 5000km basis. :

[Guest clarkewan]

i am on a mineral oil base and with some additives...

did at top speed motors....

they are good!!

i rather pay on every 5000km mineral oil service than 10k km syn oil service....

old engine definitely needs more natural lubricants...

:D

cheers...

just my opinion....

[Guest Mike]

no need to use fully syn oil on our 124 =)

[Guest mr w124]

Yup. i use semi syn. supposed to change avery 8000km but the oil usually burns off by 7000 n the warning light comes on so will change then. i will prob continue with semi syn n change every 500km to be on the safe side. was using mineral before. when switched to semi syn, could feel the power difference.

[Guest MBfallshirmjager]

OK...Thanks for the inputs chums! Point noted. My next servicing when it hits 10,000km, I'll ask the workshop to change it to semi-synthetic oil.

Cheerios!
