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.

It straight up works!!!
a year ago
It truly does what it says. I keep track of my regen cycles to a T on my ‘19 389 Pete. X-15 Cummins performance series. Normally my engine will regen once every 100 engine hours. I’ve been using Diesel Extreme every 6-7,000 miles for over 12 months now and I’ve noticed my regen intervals are now every 202-203 engine hours. Also the time parked during regen has decreased as well. I purchased this truck new and my current mileage is 824,808. Current engine hours 19,815.9. My one & only DPF cleaning was at 428,960 miles/11,108.6 engine hours. I use the performance dose of EDT at every fill up and have for years now. Thank you for an amazing product!!!
Yes, I recommend this product.

Works like magic

My marine diesel generator would only reach 40% capacity before bogging down and putting out black smoke. I put some of this in the fuel tank and circulated through the engine for an hour and then ran the engine. After about an hour of running I can now achieve full power with no black smoke. Amazing stuff.
Yes, I recommend this product.
