Today's Ethanol Blended Gasoline Destroys Carbureted Engines.


The Problem: Ethanol Corrosion In Carburetors

The growing use of Ethanol in modern pump fuel significantly increases the risk of carburetor and fuel system corrosion. Ethanol is hygroscopic, meaning it absorbs moisture, which causes corrosion in the fuel system and inside the engine. High levels of Ethanol dilution in the motor oil can lead to increased moisture in the crankcase, thereby causing rust and other corrosion problems. Plus, Ethanol by itself is corrosive to components made of Aluminum and Zinc, like carburetors. Both of these problems are compounded by long periods of storage between uses.

The Solution:Carb Defender® Fuel Additive

Driven’s Carb Defender® Fuel Additive is specifically formulated to protect against Ethanol corrosion and induction deposits. Special corrosion inhibitors work to prevent expensive repairs and diminished performance caused by Ethanol-blended pump gasoline and the moisture it attracts. This additive controls combustion chamber residue, plus it cleans and protects surfaces of the fuel system and intake tract. The 8 oz. bottle of additive treats up to 25 gallons of Ethanol-blended gas and should be used with each and every fill-up.

Before you put your carbureted engine in storage for the winter off-season, it’s crucial to make sure it has the correct protection so that it will be in proper running condition when it’s time to take it back out the next year.

Designed for all carbureted engines, Driven Carb Defender® will save you the hassle of costly post storage repairs resulting from corrosion that happens at an accelerated pace over the winter due to temperature swings. Because it is specifically formulated to protect against Ethanol corrosion and induction deposits, Driven Carb Defender® and its special corrosion inhibitors work to counteract the damaging moisture buildup resulting from the hygroscopic characteristics of Ethanol-blended fuel. Over the winter months, the Ethanol in your fuel tank absorbs moisture, which if left unprotected will lead to rust, corrosion and other costly problems. In addition, this additive stabilizes the fuel as well as cleans existing deposits in the combustion chamber.

With Driven Carb Defender®, you can rest assured that once it’s spring and you’re ready to bring your ride back out, its performance will remain the same.
