As a matter of interest, we have 3 Mercedes E class diesel cars; my older one is 10 years old and has done 345,000 miles, never had issues with the engine (the other two are catching up quickly) and so far it has had all kind of diesels fuels, good and bad; but the engine has been regularly maintained.

I fill up with the extra zoom diesel in 1 in 4 fills to help keep the system clean.

I knew a local back street garage near to where I worked who always had Peugeot cars in. When I asked him about it he told me the main dealer brings them across to be serviced and then charges huge prices just so they have a Peugeot stamp in the book.

So now what?
Still no conclusion out there. What's best for your engine is to run it often and hard :-). Does more good than adding snake oils, magnets or anything else.
We used to add gasoline in my army days (but only below -20 C :-) ).
Since engines at certain age start using some of their own oil, I cant see why adding a bit of oil to the fuel could hurt. Whether it helps the pump of the injectors .......I don't know. I would not add anything, to be on the save side. Unless its a 2 stroke diesel engine :-))))

If a motor is already buring oil giving it extra oil in the fuel will hasten carbon depositing and ring-gumming etc.
Or am I wrong?

Reminds me of a very old joke...
Two old-time, country farmers met in town one day. In the course of their conversation, Jake said to Zeek, "My mule is sick and I don't know what to do." Zeek replied, "When my mule got sick, I made him drink turpentine. The conversation turned to other things and the two soon parted company.
About two weeks later, they again saw each other in town. Jake stormed up to Zeek and in an angry voice, said, "You son of a bitch! I done to my mule just like you did to yours. I fed him turpentine and it killed him dead in two hours. What have you got to say to that?"
Zeek looked at Jake and casually replied, "Yup... It killed mine, too."Nigel
