DEF Additive
Has anyone done the cost comparison for the cost of DEF at the pump compared to at the store in a container? Which is cheaper?

Another question is how much DEF are you using. Over a 3,000 mile trip I used 4.5% DEf to Diesel. I think this is very high and have it in the shop with a request to evaluate this over usage.
Any other real world experience?
Thanks,
I average 3% on our coach. Our DEF fill is on the driver's side which makes it a bit more convenient than those that have the fill on the right but, I still have to pull forward after filling with diesel to reach the DEF pump. Having dual fill DEF as some manufacturers are doing now still wouldn't help me there.
I guess the manufacturers are not confident in my ability to not put diesel in my DEF tank so they place the DEF fill at the rearmost corner away from both of my diesel fills. :)
