How far do you fill your FL Def tank?

[Stuart W]

Stuart, I've been filling from the drivers side via Truck Stops, wait till the pump stops and have yet to have any issues doing it this way.

Thank you , I believe that was a Spartan issue only

I filled mine at the tank cap today until the nozzle shut off. A few hours after returning home I noticed a puddle had formed under the tank so I assume there is a vent that burped out some DEF as the day warmed up. I will be keeping it down a few inches in the future.

What chassis do you have?

Freightliner

I keep mine 1 bar above empty when storing. When driving, I will fill based on distance with goal of parking with very low levels.

This has worked well for me since 2012 on 2 freightliner and 1 spartan.

The key to Def is to keep it fresh.
