Is this ok on my 2015 vw golf?

BlueDEF will work in any vehicle that has an SCR system. 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.

Why is this more than 4 times as expensive than retail list price?

It must be the store selling it. Ask them.

Do you need a funnel to add the fluid from the gallon size container?

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.

Will this work for 2016 Mercedes Sprinter?

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.

Used it for my lawn

I sprayed my lawn with it (mixed with water) because the main ingredient is Urea. Cheaper solution rather than buying fertilizer. Does the same job

Good Product - price not competitive

I originally ordered this by the gallon and started a monthly subscription to have one gallon delivered each month. This past weekend I was visiting my local Tractor Supply and found the same name brand and same type of DEF fluid in 2.5 gallons for $13.00. I was blown away by the price difference and realized this local farm store was beating the lowest price that I found on Amazon by over half. Today, I cancelled my monthly subscription and will be buying my DEF fluid from my local Tractor Supply going forward. Hats off to the little stores for being able to be competitive amonst a giant such as Amazon.
