K100 G+ Gasoline Treatment 

K100-G+ Gasoline Treatment which was formerly know as K100 MG contains enhanced stabilizers to keep fuel fresh, essential for equipment that will sit for extended time between uses. This formula's unique organic chemistry will even fix equipment that has been sitting a while and won't start or runs roughly. K100 G+ Gasoline Treatment eliminates water in the fuel to prevent winter freeze-ups and phase separation in E-10, and improves fuel performance by altering the burn chemistry for more complete combustion, boosting the octane, and reducing oil fumes and toxic emissions. 


  • Prevents phase separation in ethanol blended gasoline 
  • Eliminates water and all water related problems 
  • Stabilizes fuel for up to two years, and keeps it fresh 
  • Increases Octane/Cetane ratings 1 1⁄2 to 2 points 
  • Replaces lost lubricity in LSD, ULSD and K-1 winter blends 
  • Cleans engines and fuel systems for better mileage, easier starts, smoother idle, more power and better acceleration 
  • Reduces black smoke, unburned hydrocarbons, CO and particulate emissions 
  • Reduces maintenance costs and down time and extends engine life

    Excellent product, but the bottle doesn't quit fit into the gasoline fill tube. The top should be narrower and a bit longer. ALSO, is this available in a gallon size?

    I have been using K100 G+ in my 2016 Mustang for years. Since my Mustang is my show car it may sit idle for periods of time. The K100 G+ helps keep the fuel system and carb clean. I feel that the K100 G+ helps improve power and milage. I hope that PCS continues to carry this product.

    Works like a charm. I've been using K100 for about 7 years now when winterizing my 2 cars for storage. Every year taking them out in the spring I've never had a problem and cars run like the day I put them away. I use it in my mower, dirt bikes, side by side, and my nieces four wheeler and haven't had to take the carbs out of any of them for cleaning since using the K100. It's a must for anything with gas that's gonna sit.

    K100 is the best gas treatment hands down. With the addition of stabilizer you have your cake and eat it to!

    Best fuel treatment I have used

    I use this in my boat and truck, and have used in things that are not running well. usually this clears up the problem if it is related to old or bad fuel.

    Amazing. After disassembling my Onan generators carb twice and finding a yellowish gel plugging up the bowl and jets, and the problem was starting to recur a third time, and reading about the ethanol phase separation on your web site, I transfer pumped all the gas in my 32 gallon tank to 5 gallon cans and refilled the tank with fresh gasoline, changing out the water separator fuel filter, and adding a double strength mix of the K 100. (4- 8 oz. bottles) I decided not to pull the carb again but did manage to get the generator started , and it was still surging and running badly after 15 minutes. I shut it off and left it over night with the new K 100 treated gas in the carb, and came out next day and started it, only to find after a couple of bucks and kicks, it ran super smoothly, like a kitten. I filled my old car with the old gas and added K 100 to the tank and haven't had a problem. I'm sold. Thank you.
