W124 oil pressure

[Alex2202]

Hi

I just bought a 1993 E220 (W124) with only 45 thousand original kilometers. The oil pressure gauge is almost always at 3. Onle once when engine was idle did it dro a little ( like 2.6). Is it normal that it remains at 3 most of the time?

Yes. It sounds fine. Just check the gauge does not read 3 as soon as you turn the key before the engine starts. If it does the sender is probably faulty.

Nope, it only goes up o 3 once the engine starts and stays at 3 pretty much all the time.

Nothing to worry about- as the engine warms up the oil "thins out" a bit meaning the oil pressure will drop slightly at idle as the oil pump slows down with engine revs. The bottom end of these engines is good for 200,000++ miles easy if fed clean oil at regular intervals. A good quality 10w40 semisynthetic changed at 6,000- 7,500 miles will be fine. Fully synthetic 5w40 or 0w40 oils are unnecessary unless you wish to extend the service interval considerably.

My old 220CE coupe (W124) was still holding 2.5bars of oil pressure at hot idle and 3 bars the rest of the time (except when off of course) when it reached 220k miles, no different to when I bought it at 67k. (fully synthetic oil, usual viscosity)

Agree with the above, my first W124 E220 registered the oil pressure at 3 and virtually remained there even when the engine was hot. Not bad considering I covered 67,000 miles in her.
