Question type: Maintenance & Repair

Stick a long thin screwdriver in the fill-hole and use a funnel with a very small tube and the fill-hole will be open, but why the heck to you feel you need gasoline treatments? Any major brand gasoline has everything your car needs and all that stuff on the shelf does nothing, it may have some benzene in it, but the people at Chevron/Shell/Mobil know how to make gasoline.

the 300 has a superior design with NO timing chain to fail~ It is a system that does not have a removable cap. And I don't think benzene is okay, on the contrary I did have poor wording but what I meant was DO NOT use those products because of the fact they contain benzene

bottom line...they would NOT like you to use anything other than a regular sized gas filler nozzle~

doesn't it seem like snow and dust would have an easy time of makin' it's way into the gas oh chrysler....better? this remains to be seen~

capless fuel delivery is as retarded as non port washing on direct injection systems and managed displacement and start/stop technology.

But they're all great technologies for the service department!
