Hot Shot's Secret Diesel Extreme Clean & Boost is a fully formulated and concentrated fuel system cleaner and cetane booster. Designed to remove deposits and improve the performance of all types of diesel engines, from semi-trucks to RV's, this diesel injector cleaner removes all internal diesel injector deposits (IDID's) and external diesel injector deposits (EDID's) as well as waxy and polymeric deposits that can clog the fuel filter. Our powerful diesel additive and fuel cleaner cleans out injector tips, cylinders, fuel lines and tanks, all while demulsifing moisture to deliver a more efficient system. Once the fuel system is clean, Diesel Extreme contains several premium additives to enhance performance. A cetane boost can improve cetane ratings by 7 points for better combustibility, fuel economy and horsepower. With improved combustibility, you can reduce the number of diesel particulate filter (DPF) regeneration cycles required. Use 8 oz per 20 gallons of diesel fuel. Add during fuel up and run every 6,000 miles for best results. For use in all diesel engines.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

I purchased this product for a month adding the noted amount per directions for each tank refill. Been happy except for freezing temps. I am going to add their other product for the ad blue to clean potential crystals particle after my level get to the proper fill point. One recommendation for the diesel additive I would like to see the product address freezing outside Temperatures which would assist glow plug issues protection as well.

Euro Diesel Performance Renewed

I have a Mk6 Volkswagen Jetta with the CJAA motor and dual clutch transmission. Been getting really bad mileage, even when trying to run hard to do an "Italian tune up" after fully warmed up, but was getting low 30's MPG in town/highway. Just did a single treatment in my tank and went 185 miles running hard to get it through and warm up the motor, and it was night and day fuel economy increase and throttle response. The beast is awake again, mid to upper 30's MPG on this fill up, and went all those miles while showing I could go another 390 miles. Couldn't be happier. Menards has this for a great deal. Thank you Hot Shot's Secret for your chemical additives, this one in addition to your EDT has been great.

Yes, I recommend this product.
