6.4 Mileage and water separator

[Huntr52]

New to this forum and diesels. I bought a used 6.4 w/36000 miles. Brought it home and the dealer had filled it up and Im getting a "Drain Water" alarm after driving a few miles. Drained it today, drove down the street and the same alarm popped up again? Anyone got any ideas on why the second alarm after draining? I let it run until there was nothing coming out the tube to be sure !!

The other question is how bad is everyone else's mileage. It seems Im getting around 8-11 around town. I knew it wasnt a KIA but is that about the same as everyone else is getting and if it is, is there anything, simple, that I can do to squeeze a few more MPG's out of it?

Take it to the dealer Hunter. I have a thread on here about the same problem. It is a bad sensor. I had heard all of the horror stories about voided warranty claims over water in the fuel so I would pull over twice a day and drain that darn thing. I even took mine in and had the fuel filters changed, drove away and the "drain water" alarm went off. Dealer knew exactly what was wrong when I told them. It's a bad sensor. Take it in before it drives you nuts.

Thanks for your info. I am going to call them now. Two days into it and their Certified Pre-Owned ck out doesnt seem to good. Either that or when they filled it up their tank had water.

Hopefully, it is just a sensor and they fix it.

Anybody out there got info on mileage. Ive only run this truck two days and it is steady at 8-10 in town. Any reasonable fixes out there I can afford to bring this up some???

The only way to increase the mileage is to delete the DPF.
