DEF Fluid usage
Posted: Mon Jan 28, 2019 11:57 pm
I bought a 2018 Disco HSE LUX with the TD6 engine in October. I've put just about 7100 miles on it since then. Very impressed by the vehicle overall - handling, comfort, etc are a step up on my LR4 (which I kept as well). I haven't taken it off road yet, but will in the spring. The only thing that has been unexpected is the rate of usage for the DEF fluid. I buy the DEF fluid in 2 gallon containers and when the warning comes up, I add the 2 gal. At 7100 miles I'm getting the message to add more... for the third time. That will effectively mean I've added 6 gallons in 7100 miles. That seems unusually high to me.
I drive mostly on the highway and average 26-28mpg pretty consistently. Is this usage of DEF fluid normal?
