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

It’s just Blue DEF. I wanted a one gallon size to carry in my motor home in case I ran low out in the wilderness

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

It is good to have one gallon optio instead of 2.5 gallon so I can fill up my DEF more often.

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.

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.

Delivered on time, seems to work as expected.

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.

I just get it here by the gallon when it is at a good price. It is good to have a couple of gallons in the garage handy. When I change the oil in my truck I always top off the DEF, so I just rotate these gallons through the garage to keep fresh DEF on-hand.
