In case anyone wants to know why I am happy to have an older Foretravel, pre-DEF, read this:
Diesel exhaust fluid (DEF), commonly referred to as AdBlue in Europe and standardised as ISO 22241[1] is an aqueous urea solution made with 32.5% high-purity urea (AUS 32) and 67.5% deionized water. DEF is used as a consumable in selective catalytic reduction (SCR) in order to lower NOx concentration in the diesel exhaust emissions from diesel engines.[2]
The average person excretes about 30 grams of urea a day, mostly through urine.
I am fortunate, not needing to buy and store urine for my engine to run.
