I filled it up with adblue today it took about 15l, I will see how long this lasts.
The process to fill it is beyond a pain in the **** though with airlocks in the drum and spillages is there an easier way?
I bought a 5l oil pouring jug but is not quite the answer either.
i would quite happily have my 75l diesel tank and no adblue like I did with my old one, the 60l tank is too small for the mileage I do.
How about an additional long range expedition tank, they're pretty popular in Australia.
