Better not to store Adblu
all our buses / coaches, cars MH use adblu and from experience we do not store Adblu.
we only fill up at a filling station at the pump
they have a high turnover and your pretty well guaranteed it’s fresh stuff.
we used to buy 45 gallon drums and the troubles we had were unbelievable.
make sure you give your MH a decent blow out run.
either drop down to 5 th gear and run it for a few miles or if your happy drive it at 70 mph in a safe place to do so.
although all our buses are in constant use being governed to 62 mph does cause problems. We often run the at 62 in 5th gear for several miles.
Vehicles we use are Ford, Mercedes, Iveco bmw and Fiat. And now have very few Adblu or regen problems.
we would never use knowingly out of date additives.
