Five Star DEF Launches First Products – Limited Offering (Coming 10/22)!

Oct 15, 2013

Five Star DEF will be available in limited quantity starting 10/22 for immediate order and delivery. We’ll ship within 48 hours of your order.

We are offering 190 of our Basic Kits and 90 of our Refill Kits as a test of the demand for our product. Price is $12.49 plus shipping for the basic kit and $9.99 for the refill kit. If we sell out quickly, we’ll scale up to meet the demand, and remove the “limited” from our offering. We’re prepared, and committed, to meet demand of up to 5,000 units/month, but this will take some time. We’ll keep you up-to-date on our progress. 

It is up to you, our customers, to determine demand. Tell us how we can improve. We are a small business with big dreams!

Drop us a line at  We are already working on a 6 liter container for our basic kit that is easier to store, but still makes our 1.36 gallon kit. We are also evaluating smaller and larger Basic Kits, (.68 gallon and 2.72 gallon).  We will also have a funnel available for purchase soon, which is ideal for making sure you get *all* the distilled water from a grocery store gallon and *all* of the urea from one of our Refill Kits into your Five Star DEF Container. Our other accessories: DEF compatible gloves and replacement Five Star DEF Filters will be available for purchase soon.

Do you own and operate a small farm? Operate a fleet of diesel pickups away from population centers? We are working on solutions based on our dry urea, local distilled water, approved material containers, and other features for you that may be better than ordering a 330 gal tote from BIG DEF. Let us know, and we’ll get to work on this soon.
