We normally top up adblue in our Fiat Ducatto based motorhome within a few miles of the warning light coming on.
Now I understand the reserve is around 5ltr in a 15ltr tank. So there is always some old adblue swilling around.
Initially it took 10ltr to fill up tank. Then last year 9ltr. This last fill up took 7.5ltr.
I am concerned that the old reserve adblue has degraded and affected the new adblue or in some way affected the warning light levels.
Our motorhome was also in storage for 3 months before being used again for our Spain trip. Unlike trucks and cars and commercial vans, motorhomes can have long periods of storage. Unlike diesel, adblue does have a shelf life.
So what are the thoughts of other adblue motorhome users?
Have you noticed changes to your adblue system and performance over time?
Does crystallisation of old adblue in the tank affect its capacity and eventually requiring maintenance of some sort?
