Designed for Carbureted Classic and Performance Vehicles, this Concentrated Additive Prevents Costly Repairs and Poor Performance Resulting from the use of Corrosive Ethanol-Blended Pump Gas or Flex Fuels
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. High levels of ethanol dilution in motor oil can lead to rust and other corrosion problems in the fuel system and inside the engine. This new additive, however, controls combustion chamber residue, plus cleans and protects surfaces of the fuel system and intake tract. An 8 oz. bottle of additive treats up to 25 gallons of ethanol-blended gas, and should be used with each and every fill-up. Driven Racing Oil™ Carb Defender™ Fuel Additive keeps the carburetor functioning properly and is designed for the unique needs of classic vehicles that spend much of their lives in storage between cruises and special events.

I am still using the Carb Defender in my 1969 Plymouth 426 Hemi Road Runner. No problems with the fuel system, carbs, and my original 426 Hemi has still not come apart. This is a superior product, just like I have experienced with the other Joe Gibbs Driven products. And yes, I use the Joe Gibbs Driven Conventional Hot Rod oil.

Guessing product is fine. Had a problem with the shipping. Fed Ex fault, 2 bottles empty when received. Wrote Driven, had 2 new bottles within a week, no charge for product or shipping. Very pleased with Driven. 1967 Corvette, all original.

Just spent $500.00 rebuilding the carb on our 70 Challenger. We talked to several people at recent cars shows, several had heard of your product, but none had used it. We are keeping our fingers crossed that Carb Defender will eliminate any further carb rebuilds.

hasn't been long enough to tell how good or bad the product is--I have 23 vehicles some may sit awhile and that is when I will be able to judge as to how well they well perform using this product---tried another carb. product on my 56 tbird and 48 chevy after sitting 4 or 5 months had to rebuild both carbs so time will tell

I have been using Joe Gibbs Conventional Hot Rod 15W-50 in my restored Hemi Road Runner for years. This is with out a doubt, one of the best motor oils available anywhere. I have also been using Joe Gibbs Carb Defender with every fill-up. This is one of the best ethanol protectors available. I have used several of the other brands. Joe Gibbs Carb Defender will satisfy any classic carbureted cars need to ward off the ill effects of ethanol mixed fuels. You also should try Joe Gibbs Race Wax!
