I recently purchased a mercedes 220d. I dont have a manual yet. The car is in excelent condition only 70 thousand org.miles Iv been looking over the engine.On the fuel injector pump there is a red cap with the letters OEL stamped on it. Can anyone give me imfo on this?
Thanks

 

OEL=oil--meaning stuff that lubricates

 

Hey Thanks for the translation of OEL 'stuff that luborcates.' but I guess that I was a little vague about the problem.I need to know what kind and how much oil is to be used in the pump?

Thanks

Typically injector pumps uses the same oil as the engine. As a word of caution though, petrol causes above than normal wear on the injector pump , as it's lubricating properties is not as good as diesel.

 

The oil to use is the same you use in the engine. 1/10 of a quart is about right. Using too much simply runs out via the overflow pipe at the back of the pump. Hope it answers your question.
