How big is an adblue tank? My Merc gives me not a lot more range than one full tank of diesel does. Is that normal?
Not big enough if your boss has his own adblue tank and you’re tramping. My 480 Actros will do two tanks of diesel before adblue gets critical; so to answer your question I’d get the adblue consumption checked, seems a bit high. I carry a couple of 10 litre cans to top up if I’m out all week, as the cost is half of what the forecourt pumps charge.
If you do that, a couple of tips. Firstly make sure the cans are well sealed, secondly if you’re filling them from the yard pump make sure to use them regularly.
