"Having been a large lawnmower sales and service dealer for over 37 years, I was skeptical of the product when I first heard about it. But since trying it myself and recommending it to many of my customers (We sell it in our store, now) I am very impressed in how this works. Most additives that I have evaluated fall way short of expectations, in fact most I have tried were outright scams. Not "Mechanic in a bottle". Many of our customers that have units that do not run correctly due to restricted carburetors that have been gummed up by old gas sitting in them, have been able to use the "Mechanic in a Bottle" as directed and save a very costly carburetor cleaning and rebuilding. The stuff is really amazing. Keep in mind, though, that there will always be some carburetors that are too far gone to be corrected by this product and will still needed to be rebuilt or replaced, but I would always recommend trying the "Mechanic in a bottle" FIRST. In addition, it is one of the ONLY products that seem to be a very good fuel stabilizer as well. Older versions of fuel stabilizers just plain DON'T WORK! The same company also makes a product called "Ethanol Shield" This is nearly the same product, but does not have the same cleaners and is mainly used to stabilize gas for storage. Both will do nearly the same jobs except the "Mechanic IN A Bottle" has the very special cleaners that are made to completely dissolve the varnish and restore the fuel to its usable state. I give this product a 5 Star rating."

Engine Energy is a High Energy Fuel Additive that is actually seven (7) fuel additives in one (1) great product.  For gas and diesel engines, this product not only increases your engine’s horsepower and Octane while increasing your mileage, it also cleans and protects your engine from today’s fuel related issues.

With greater BTU, improved lubrication, and better hydrodynamic ring seal, average horsepower increases 15%. Engine Energy contains components that improve engine ignition, therefore reducing fuel consumption. The BTU of the fuel is raised, resulting in more consistent and complete combustion. Higher BTU contributes to a much better fuel charge with more power and a dramatic reduction with emissions. On average, fuel usage is reduced up to 15%.

Engine Energy increases octane up to 5 points in gasoline. Use regularly to keep entire fuel system and combustion chamber clean. Contains a fuel catalyst that prevents rough idling, stalling, after-run, and pre-ignition pinging.

Engine Energy prevents water buildup, prevents fuel system corrosion, and prevents ethanol phase separation. Engine Energy has been specifically developed for extended storage of gasoline engines. It contains antirust and antioxidant fuel additives to inhibit rust and oxidation. Prevents formation of gum and varnish. Specially formulated to disperse moisture in fuel. Assures easy start-up after storage.

Engine Energy reduces hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx). This reduction is due to an increase in complete combustion. Unlike petroleum distillate fuel additives, the detergent in Engine Energy promotes full volumetric efficiency allowing for continuously clean spray patterns.
