Does anyone here use an additive in their diesel engine.
My diesel is over 100K miles and I thought would an additive help with economy etc.

Most of them seem to be snake oil.
well almost, having read a few reports most (the well known ones) are just grades of detergents.
You could try Shells super-v leaded - Its a couple of p per litre more however its supposed to lubricate the diesel pump, improve emmissions, performance and mpg. No harm in filling up just the once - I use the super-v unleaded and the improved MPG makes a no difference in cost at the end of the day (around
2mpg better but more costly per litre) however I think the cars slightly more responsive and the other benefits also help
Most independent tests show that the extra performance effect of these premium fuels is just a placebo effect.
