K-100 is a remarkable organic formulation that bonds itself to water and renders it completely burnable as fuel water reduces the heat of combustion which means more smoke, less power, hard starting, rough idle, poor mileage, winter freeze-ups and microbe growth. Use K-100 fuel treatment regularly so your engine will run cleaner, run stronger and run longer. What K-100-g does: Eliminates water and water-related problems. Improves overall engine efficiency for more miles/gallon/hour. Eliminates freeze ups that block fuel lines and filters. Eliminates free water and cleans engines for easier starting, smoother idle, more power, better acceleration. Prevents phase separation in e-10 fuel. Prevents injector tip failure. Adds lubricity to reduce friction in the fuel system. Reduces cold-start scuffing on 2-cycle engines. Burns cleanly and completely leaving no ash deposits. Dissolves gums and varnishes. Cleans carburetors and fuel injectors for better mileage. Dissolves asphatimes and puts them back into the fuel. Modifies burn chemistry for more complete combustion. Reduces carbon monoxide (co) emissions by 80-90%. Reduces unburned hydrocarbon (hc) emissions by 65-80%. Reduces oil fumes from 2-strokes, premix or auto-inject. Extends fuel injector pump life. Increases octane ratings 1-1/2 to 2 points. Upgrades lower quality fuel. Excellent for use in e-10 gasoline. Excellent for use in both 2 and 4 cycle engines.

Works as advertised. The only chemical base product that actually bonds with water in a molecular burnable ratio that goes up into steam in the firing cycle.

I left gas in my boat too long, used two bottles for 225 gallons of gas, Took the boat on a trip and noticed the rpm’s increased by 600rpm. Worked as described.

I bought this to see if a faulty water sensor, check engine light, and water in the fuel could be remedied without having to drop Mercedes tank. It stopped the check engine light from going on, allowed the water to be burned over a couple bottles. It will not fix something that is broken, of course, but fixed my problems. Some of.these additives seem like snake oil, but tthis one seems to be able to mix the water with fuel so it can be safely burned. Highly recommend.

I reordered as the product is great but the shipper broke and the supplier didn't have more to ship but refunded me quickly

Je crois que c'est le meilleur liquide pour traiter l'essence que nous mettons dans les petits moteurs, surtout que maintenant au Canada, il y a de l'éthanol dans toutes les catégories d'essence.

The price went up, delivery was late,packaging leaked. But I have been told it is very good, so let's see. Maybe it is worth it.

The last three times I have ordered this product in the one quart size from Amazon the bottles were leaking when I opened the package. The K-100 for Diesel lost about an ounce of product. I'm not sure if the product itself softens the seal on the top of the bottle and it begins to break down and leak or the manufacturer needs better seals on the bottle. The product also seems to soften the teeth in the cap when the leak occurs making the child-proof cap a real challenge to remove. No complaints about the product, it's just the packaging or shipping methods that need some improvement.

As a teenager, I worked for my father as a small engine mechanic. The most common problems were always related to fuel and the carburetor. Inevitably someone would leave their lawnmower with a black gas tank out in the sun all summer and their gas would turn to varnish.A salesperson showed up at my father's business pitching a revolutionary new fuel treatment. We were skeptical, but the results were enough for my father to carry the K100 line.K100 is amazing. I'm sorry if I sound like a shill. I'm as much a K100 shill as I am a Vanguard shill. I stick with what works. Sea Foam is a great product, but it's not as effective and it doesn't combat the presence of water. K100 claims to "make water burn". I doubt it... but no matter what the problem has been, K100 has made my engine run again. There's no other product like it.Recently, I decided to resurrect an old, disused 1991 Honda VFR750F motorcycle. It ran, but it fired on 3 cylinders. I dumped 6 oz. of K100 in there and all carburetor problems were gone.This morning, I put a couple ounces of K100 in my lawnmower which has had carburetor problems for the past couple years. I'd had the bowl, float, and needle out and cleaned the jets manually. I had given up. It's embarrassing to have been a small engine mechanic for YEARS and not have a running lawnmower.Next time before you think about tinkering with a carburetor, try this stuff out. I bought a spare bottle for myself and one for a friend who's a VW enthusiast. It works with gasoline and diesel and there's a specific blend for marine applications.It's fine for fuel injected engines as well, but I can't vouch for its ability to clean injectors. For that, I still recommend pulling a vacuum line and sticking it in a glass of Sea Foam, flooding it out and letting it sit. If you have carbureted engines, K100 is an excellent product to have on hand.
