Cleans fuel systems and injectors while restoring diesel performance.: Fuel System Cleaners - desertcart.com ✓ FREE DELIVERY possible on eligible purchases Review: Love This Stuff - This pairs very well with my 2018 International 4300 Durastar box truck. It has hit the 600,000 mile club and keeps going strong. I have started noticing my fuel tank guage no longer reads correctly and almost took a stab at replacing the fuel assembly unit for a few hundred. I went ahead and got some of this HotShot Secret and poured a 1/4th or 1 Qt for my 70 gallon tank. Beleive it or not, my fuel guage had restored its range after one tank. This pattern remained for about 12,000 miles until it started happening again. Used another 1/4th and got another 15,000 miles. The pattern is slowly going away so this shows that the tank is in fact getting cleaned out which was ongoing with affecting my sensor. MPG has not seen a rise. If anything it has seen a dip from 9.1 down to 8.9. But if it means burning clean with injectors and such, this is not a loss. Effective and great savings for the gallon. Looks good and easy carry size. No stickiness to worry about. Review: Increible producto - I’ve been using 4 type of diesel addictive for over a year. Diesel extreme every 4k or 5k miles. Everyday diesel treatment on each fuel charge. Winter defense on winter season. Winter diesel anti-gel when temperatures get below 10F. I have a more power, less black smoke and just look how my exhaust valve are. It’s a Detroit 60 series that works every day with 390k miles after overhaul. My truck is part our my family, feed my family and it deserves the best to keep running and running.

Which came first?! My bottle says 6,000 miles… this bottle is about 10 months old. I’d really like to know if the manufacturer recommends 6k or 6 months! Thanks **Q: Would this product be suitable for a 1.6 Diesel engine in our family car?** A: I use it it a 1.9 TDI and 2 7.3 diesels. **Q: Has anyone used this with a TDI with DEF / Urea?** A: It is specifically designed for restoring the performance of diesel engines so yea it will be fine in your TDI just make sure you follow instructions don't mix it too strong or your car will run like a raped ape for a minute **Q: I want to use this in a diesel parking heater to try and remove some of the carbon buildup inside the burn chamber. Do you think this would do that?** A: It is very unlikely that using Diesel Extreme will remove carbon that is already built up in your heater. It is best used as a preventative to combat the amount of soot/carbon build up. Another note is that unfortunately, Diesel Extreme is very odorous and using it in an open heating element may cause some unpleasant odors. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love This Stuff *by J***I on January 3, 2026* This pairs very well with my 2018 International 4300 Durastar box truck.

I love this product ### ⭐⭐⭐⭐⭐ Better then advertised *by J***T on May 22, 2026* My mechanic found rusted Fuel injectors, and said at some point they would need to be replaced. I tried this in the interim and the first bottle worked immediately. So now I add half a bottle to a full tank every time I fill up and I have had no problems. This does not mean the rusted fuel line will go away with this product. ## Frequently Bought Together - Hot Shot's Secret Diesel Extreme 1 Gallon, Concentrated Fuel System Cleaner, Diesel Fuel Additive, Injector Cleaner - Increases MPG & Restores Engine Performance - Hot Shot's Secret - HSSEDT01G Everyday Diesel Treatment - EDT 1 Gallon - Treats Up to 3,200 Gallons - Hot Shot's Secret LX4 Lubricity Extreme 1 Gallon, Fuel Treatment for All Engines, Gasoline & Diesel Additive, Fuel Additive Increases Lubricity, Protects & Extends Fuel System Life --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/203045704-hot-shots-secret-diesel-extreme-fuel-additive-1-gallon](https://www.desertcart.sn/products/203045704-hot-shots-secret-diesel-extreme-fuel-additive-1-gallon) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-26*
