We use K100 in our diesel motorhome, I get the 32oz bottles and follow the directions on the label. The bottle instructions say it treats 250 gallons (I think). I divide 32 oz by 250 gallons that gives me .123 oz per gallon pumped. I multiply the gallons pumped by .123 to determine how many oz to add to the tank. I am generally pumping 90 to 110 gallons per filllup. I use a plastic bottle that has an oz scale up the side and a long neck funnel to add the K100.

What is the mix ratio? Oz's of k-100 to gal of diesel?

1oz per 8 Gallons of Diesel in Warm Weather1oz per 5 Gallons of Diesel in Cold WeatherThis is close to the recommended mix... I myself just add 1oz per 5 Gallons in both climates and it is working fine for me...

Hello, can I add frontier 2004 diesel? how much per full tank?

1 oz, per 7.5 gallons summer use. 2 oz per 7.5 gallons of winter use

how much per gallon do I need to use..,i have 80 gallons of diesel

I use about 1.5 ozs. per 5 gallons. So for 80 gallons of fuel works out to about 16 ozs. Ratios are on the bottle. I add about 2.5 ozs. per 5 gallons for winter use.

This is a large bottle that will last quite a few years... only a few cap full at each fill up and no more worries about water in the fuel. Plus saves money on filters you won't have to change!

We use in our outside heating oil tank. In the Northeast, during the extreme cold months (DEC-JAN-FEB) we are at risk of oil congealing. This product has enabled us to use # 2 heating oil rather than K-1 fuel which can be $2-3more per gallon. We have experienced no congealing, it disperses any condensation and burns cleanly. Our burner tech was amazed at the cleanliness of the burner filter and oil nozzle. Well worth the cost verses paying extra for the K-1 or extremely costly service tech bills. Works for us!
