DEF?

Thank you very much KW.... I did read quite a lot... and saved it for later... very interesting. It's sad the guy will not be coming back to this forum... He seems to be such an endless well of information... Priceless... And I also found other websites/forums with tons of info on engine performance and such...

 

i dont know how you guys are getting 1500 miles per 1/4 tank of DEF, i get approx 1100 miles per tank of fuel and i have to add at least 5 gallons every ohter filup if not more

 

How big is your DEF tank?

 

10? gal mayb 12

 

I think mine is double that size. I can go for over a week on one tankful. I can go from Shelby MT, to Sioux City, IA, over to Toronto, ON, around to Winnipeg, MB to Calgary, AB and back to Shelby on a full tank. If I remember correctly.

Something has to be wrong with yours.

 

well i only get 63 MPH truck and 5-6 MPG too

 

I drive the same year Cascadia that does this sometimes. The amber engine light will come on and tell me it's running out of DEF when the gauge reads 2 or 3 bars, and it is out when I fill it up. but it's a DEF hog that eats 4-5 gallons for every 150 gal of fuel.

 

When you have a box of DEF on standby and want to see just how far it will really go.

 

Volvo has a gauge like the fuel gauge. I've gone about 2800 miles and it's dipped just below half.

 

Like PackRat my newer Volvo is a 780 I get about 5600 to 5800 per tank depending I seem to use more in the mountains than elsewhere. My old volvo also a 780 doesnt use a drop nor does it have regen or any other such equipment. Long live the 2005 to 2007 Volvos.
