My diesel engine has a lot of miles on it and hasn?t had any problems, so why do I need to consider a fuel treatment?
With today?s mandate ultra low sulfur fuel by EPA, it is necessary to use a lubricity additive as well as a heavy detergent. Injector designs are going to multiple ports for better fuel atomization thus injectors are plugging much easier than old designs. You should use a fuel conditioner to protect injectors and fuel pumps.
When do I have to use a multi-functional fuel conditioner?
Whenever the temperature is under 30 degrees Fahrenheit one should use a multi-functional fuel conditioner. This is not just for the anti-gel additives necessary to prevent filter plugging but detergents necessary to combat soot in cold temperatures. Cold weather requires more than twice the amount of detergents and corrosion inhibitors as warm weather operation.
