Picked up our new Ecodiesel Rubicon last week. I've decided to run the Amsoil All-in-one additive to add lubricity to the fuel and brought it with me. The filler on the Ecodiesel has a nozzle discriminator to keep the wrong fuel from being added. Jeep sent the gas burner emergency funnel with mine so I had to use my pocket knife to get it open. Not cool. Also, the truck stop down the road has the bigger nozzles that won't fit the opening. I know there are adapters for the nozzles but I really don't want anything with diesel on it riding in the cab. Watched a few Youtube videos of the Volkswagen guys popping the discriminator out of their fillers with relative ease. I would like to remove mine as well. Anybody done this mod? Looks like you have to pull inner fender to get to everything and I haven't had a chance yet.
