what is a good type of fuel additive for a diesel?
PM-17-B and PM-18-B from your local friendly Ford dealership. One is a fuel cetane booster. The other is a fuel anti-gel additive for use in colder ambient temperatures. Both retail for about $5.00US. Each bottle treats about three full tanks of fuel. Hope this helps.
at the dodge dealership we have some stuff called diesel de-carbon for the cummins engine. its made by mopar and its recommended on a couple of TSB's for poor or rough idle. in the winter you will want to use a anti-gel in your diesel fuel.
Biodiesel is a great additive.
