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?

I think the "average" usage is about 500miles per litre, mine isn't far off that, bit more when towing.
At that sort of residual mileage it looks like it’s been recently filled/topped up?
Mine stayed around that for several weeks after JLR did a free top-up but has eventually started to come down again. Took several hundred miles before it started counting down again.
