Sure couldn't get any easier to remember that I'm in the truck and it drinks diesel NOT gasoline with a green cap that requires to be unlocked each time I fill up.

As I grow older and have diesel as well as gasoline vehicles, the GREEN cap reminds me that diesel goes in that particular vehicle. It also locks so as to keep out any foreign material a maladjusted individual might try to introduce into my fuel system.
