GLK250 DEF anti-crystallization additive
I wanted to ask the community, has anyone used the DEF Additive that is promoted to prevent DEF crystals in the tank, the DEF injector, and at the NOx sensors? Not on the recommendation list for MB but it is supposed to solve this problem of crystallization. There is a similarly promoted product made by

Liqui Moly: DEF Anti Crystal Additive Concentrate (Europe)https://www.liqui-moly.com/.../def-a...ystal-additive...
and

Rislone (USA)
