Peak BlueDEF Diesel Exhaust Fluid, 1 U.S. Gallon

DEF usually comes in a big bulky 2.5 gallon box with an awkward nozzle that gets more DEF spilt than in the tank. The 1 gallon container makes it a lot easier to pour and travel with.

1 gal containers are easy to handle, I've discovered that when my DEF gauge is at 1/2 it takes one jug.

BlueDEF is the highest rated diesel exhaust fluid available and I cannot find in in one gallon jugs at any retail store. Amazon saves the day again. I use these for traveling and because it’s much easier to pour than the 2.5 gallon retail size. The cost is the same per gallon as the larger jugs so it’s a great value.

Good product

This size is easy to use which is why I would recommend it.The price was higher than Chevron but they didn’t have any at the time.
