Hi all! I'm currently in Vermont and it's time to top-off my DEF so I stopped Wallmart and the only DEF they had on the shelf was their own private label (sort of) "SuperTech". The date appears fine but I'm a little concerned with using Wallmart's product. The price was certainly right as it was about $8.00 for the 2.5 gallon container. To date I've used Peak's Blue DEF in my unit. While I did purchase the DEF I've yet to put it into my unit. Given how important DEF is in our Sprinter chassis I thought I'd check with you all to get some feedback on whether or not it's a good idea to use their product. Thanks in advance for your input.
