Product quality speaks for itself. The delivery time was spectacular !! Received my order way ahead of schedule. Can't guarantee that for everyone - this time it was fast.

Don't use the gas station DEF

For trucks other than diesel haulers, this is the only stuff to use. The stuff from the station pumps could cause thousands of dollars of damage. It's just not as fine as needed for pedestrian vehicles. I highly recommend this product.
