Does anyone ever use a lubrication additive to your diesel tank ?
I know that older type diesel engines were designed to use 500ppm diesel so that the sulphur content was used as a lubricant for the injector pump parts and injectors.
Newer diesel engines are designed to use 50ppm exclusively due to the greater pressures they operate at, being common rail diesels.
I've been told that some of the new generation common rail engines will be designed to run on 10ppm only. Anything else in the tank and the warranty will be void.
Problem is I've never seen 10ppm at fuel stations.
To get back to the point...

Does anyone use an additive, and if so :
1. What brand ?
2. Where do you source it from ?
3. Are the results noticeable ?
4. How long have you been running it for in your diesel ?
I used to buy pharmaceutical grade acetone and put 50ml per 5L of diesel into my Land Rover 300Tdi I had once upon a time.
That used to clean it out really well

That engine ran with no smoke or any issues (not even a break down...in a Land Rover mind you) for 340 000km. Then I woke up, sold it and bought a real 4x4

Well, actually... a certain 4x4 shop that I won't mention wrecked the vehicle when I took it in to fit a suspension kit. It just fell apart after they were through destroying it
