Does anyone have any thoughts or experience on the use of fuel additives? I'm thinking of Redex, who do an additive which (they claim) cleans the fuel injection system on a diesel, but there are also others such as STP.

 

I have had very good results with all of them. They all pretty much have the same ingredients mostly a mix of petrol and paraffin. The blue redex bottle says to use half every fill up but I use the full bottle every 3000 miles. Certainly makes a big difference in smooth running, starting and smoke reduction under acceleration. Much cheaper than taking your injectors out and having them redone.

 

Thank you GP :-)

 

marvel mystery oil works great too just a liitle higher priced than some of the others

 

Used redex now for the last 1200 miles or so. I seem to notice blue smoke from the exhaust now as I start up (maybe I just didn't notice it before), but it disappears after I've let it idle for a short while.

Fuel consumption has improved slightly - getting around 43mpg on a steady motoryway run instead of 41mpg - saves about £2 per 10 gallon fill, just about pays for the redex so not bad.
