Daryl at Marathon in Texas showed me a trick...
Use the big nozzle, but stuff about a dozen of those tri-fold paper towels available at the gas station in and around the fill door space. They do get diesel soaked, but then it doesn't spray all over the place. Then using your gloved hand, remove the paper towel and throw it away. Or, squeeze it out of the paper towel into your tank. (That's about $3 worth, right?
)
I know I go overboard, but I also wear rubber boots and big chemical gloves when I fill up. Then, my first stop when I go to pay is the bathroom where I wash my gloves. They truckers laugh at first, and then they say "ya know, that's not such a bad idea." Duh! Diesel stinks and it will give you cancer if you expose yourself enough to it. The boots are so I don't track it back into the coach. Takes an extra 30 seconds. Totally worth it I think.
One question.... if you fill from both sides, as was said in a previous post, why no big splash? Might it be that the pressure is relieved? Could one just open the other door and still fill from one? Could be worth some trial. This diesel spillage thing isn't good for anybody. Makes a mess, wastes fuel, bad for the environment....
