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. **Q: What is the mix ratio? Oz's of k-100 to gal of diesel?** A: 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... **Q: Hello, can I add frontier 2004 diesel? how much per full tank?** A: 1 oz, per 7.5 gallons summer use. 2 oz per 7.5 gallons of winter use **Q: how much per gallon do I need to use..,i have 80 gallons of diesel** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love this product *by J***D on June 21, 2026* Great product, have been using for years. ### ⭐⭐⭐⭐⭐ Restores lubrication to ultra low sulphur diesel *by V***O on April 20, 2026* Price is below that of automotive stores.
