There is only one formula and certification for DEF which applies to all vehicles. BlueDEF is ISO 22241 (which includes all four sub standards 1-4) and API certified, which is the only requirement for use in a Volkswagen vehicle. **Q: Why is this more than 4 times as expensive than retail list price?** A: It must be the store selling it. Ask them. **Q: Do you need a funnel to add the fluid from the gallon size container?** A: If you can get your hands on a nozzle that comes with the 2.5 gallon. It will fit on the one gallon jug. I just bought a one gallon and found a used 2.5 gallon jug at a gas station garage can and screwed right on and put it in my def tank. Just make sure the nozzle is clean. **Q: Will this work for 2016 Mercedes Sprinter?** A: Yes I had a 2016 Winnebago built on a 3500 sprinter chassis and used it. I now have a 2018 Thor built on a 3500 sprinter chassis and use it all the time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use *by B***. on 2 August 2018* Good product ### ⭐⭐⭐⭐⭐ Good product for diesel vehicles *by S***R on 18 February 2024* Delivered on time, seems to work as expected. ### ⭐⭐⭐⭐⭐ Used it for my lawn *by N***H on 9 March 2024* I sprayed my lawn with it (mixed with water) because the main ingredient is Urea.
