ASK THE EXPERT – WILL FUEL ADDITIVES HELP WHEN DRIVING OFFROAD ?
I have heard good and bad things about additives that you can put into the fuel tank when you are filling up. I’m not sure whether they do anything though, what are your thoughts on using fuel additives?

Additives are not something I really recommend or push.
For the right purposes, yes, they may possibly help from the very beginning, to stop a build up of deposits.
However, I do find that some products can actually be corrosive and in some cases have an adverse affect on the fuel system. I believe that if something needs fixing it should be fixed correctly. Worn injectors ultimately need replacing.
If you really want to use an additive then maybe check as best you can with the company to make sure it will not be corrosive in any way, not only for the injectors but also all of the other components in the fuel system like the injector lines and rails.
The best advice before taking your rig offroad for extended periods would be to service the vehicle correctly and regularly replace things like fuel filters.
Hope that helps
