MK-FO16-06-6PK Fuel Optimizer, 16-Ounce, 6-Pack

After reading reviews plus as any other product advertised claiming bells and whiles, I was skeptical is it does what is says, since it was on sale, I bought 1 bottle for testing and see what it would do, since I just overhauled my Ford Crown Vic 4.6L V8 it had misfire issues, pinning under load, rough idling and power loss, the wearher heat also affected the performance of the engine do to heating and cooling problems, so after fixing what need it to be fixed I had Premium quater tank left, since this car is programed to run on 87 octane the Premium fuel only prevented pining under load most the time but it made the car run under powered, anyways I drove out the gas to almost empty with half a gallon fuel left It says to add 1oz per 10 gallons I decided to add 3 oz and filled up the tank full to 18.5 gal max, started the engine while leaving from the gas station I still felt not much power do to left over old fuel in lines with in 5 minutes of driving suddenly the engine smoothes out and no rough iding, I noticed increased power like no other, the engine started running like I remember buying it 20 years ago, under load no pining no misfires, good power pull up the fill no hesitation, of course it did had mechanical problems and got fixed but the engine still wasn't running perfect it had some hesitation, but now it's beautiful, I normally don't like to write reviews but this product deserves it, it sure lived up to its promises, for 13$ it treats up 160. gallons that is cheap, in my opinion is better than other more expensive products on the market, time will tell I will post follow up update if my milage got better after I empty this gas tank. give it a try its not expensive follow the instructions if you have a dirty engine put 1.5oz per 10 gal it shouldn't hurt just don't over do it.

I have this in all my gas powered engines. The jeep, both snow blowers, weed eater, leaf blower and chain saw. The weed eater, leaf blower and chain saw starts easier and all engines run smoother. I highly recommend this stuff. I also use their MotorKote hyper lubricant any place you would use regular oil. I coated all the door hinge pins in my home with it along with the dog clipper cutters, tools with moving parts like pliers, the moving parts on my jeep like door hinges, even in the 4 wheel drive transfer case and transmission. And both differentials. MotorKote says it is safe for power steering units so I added it there, too. This stuff works far superior than just oil. And if you watch a video on the MotorKote website (it is the last video on their video page) you will see amazing proof from an independent farmer who tested this product in a small engine. He drained the oil, treated the engine with 50% MotorKote and 50% regular oil. Let the engine run for five or ten minutes then drained the crankcase and filled it with just water. He ran the engine for an hour and there was no damage to the engine!

1 ounce per 10 gallon's of fuel. DO NOT over pour. Because it's highly concentrated. My 22 year old F-150 run's like new using this and my 2000 Jeep Grand Cherokee 4.7 went from 16 mpg to 22 mpg on the open highway cruising at 70 mph. 18 mpg city. I mix one ounce of Upper Cylinder Lubricant with the Motorkote Fuel Optimizer every other fill up. I prep all my gas this way. So, my Snow blower, Tractors and Motorcycle all get this treatment every fill up. Amazon has the best price plus free shipping. Experience a quality product. It's worth every penny.

Easy to use, but you need to know when you have almost exactly 10 gallons in your tank. Be sure you don't top off the tank until you have used up almost the whole tank of gas. Because it removes water from the fuel, it will help keep your tank from rusting, which can then clog your fuel lines and injectors. That also means you won't suck up bad gas if your tank runs low. They recommend doing this every 3 - 4 fill ups, but even if you only do it once or twice a year, it can only help.

If you're not using Motorkote products, you're doing it wrong. Motorkote products literally protect and improve whole engine life and performance. Want to save and extend the life of your vehicle? Buy Motorkote products and use as directed. Their products aren't even that expensive, but it'll help protect and improve the performance of your engine.

Keeps engine running clean.

Overall I'd say this is a pretty good product. It works well and I saw a very small and effective change after one use. I really like that it does multiple things and it's very universal for cars. I'd repurchase this again.

My son turned me on to this product. He is an over the road trucker. He gets about 4 extra miles per gallon. I started to use it in my two cars, a Prius and a BMW 528i... seems that it does actually add a couple miles per gallon, more importantly it gives the engines more pep... probably doing its job to clean the injectors.
