Got great MPG out of California diesel 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. ## Features - Clean Out The Tank, Lines And Injectors - Remove Free Water From The System - Stabilize Fuel, Boost Cetane - Lubricate The Fuel Pump And Injectors ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0053PLFYM | | Best Sellers Rank | #971 in Automotive ( See Top 100 in Automotive ) #6 in Diesel Additives #7 in Fuel System Cleaners | | Brand | Hot Shot's Secret | | Brand Name | Hot Shot's Secret | | Customer Reviews | 4.7 out of 5 stars 5,812 Reviews | | Global Trade Identification Number | 00837654914205 | | Included Components | 2 QT bottle | | Item Form | Liquid | | Item Highlight | Treats 160 gallons.

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 ### ⭐⭐⭐⭐⭐ Excellent product *by D***N on August 23, 2026* Simply works !

I thought nothing could beat Liqui Moli Super Diesel Additive but this does on value for the money and the torque increase is as equal to SDA. I use this in my mint condition 2015 Golf TDI. I did not think anything could quiet my engine but after this I can barely hear it on idle yet it screams when I drop the foot pedal. I’ve used Costco’s premium diesel religiously for years but this significantly increased torque. It states to run it every 6,000 miles that’s every 12th tank of gas in my TDI. I use about 4.2 oz per tank of gas so it’s dirt cheap. My main goal is to keep carbon deposits at bay so the performance increase is legendary. I added about 2-5 mpg on average getting getting 50 mpg with gas saving driving including speed limit on freeway and coasting. When I’m done with this bottle I’m going to try the every day version and I’ll report back. ## Frequently Bought Together - Hot Shot's Secret - P040464Z Diesel Extreme Clean and Boost - 64 fl. oz. - Hot Shot's Secret HSS64Z Original Stiction Eliminator 64 Fluid Ounce Bottle, Green - Hot Shot's Secret Everyday Diesel Treatment 16 Ounce Squeeze Bottle (HSSEDT16ZS) --- ## 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.fr/products/4641434-hot-shots-secret-diesel-extreme-fuel-additive-64-oz](https://www.desertcart.fr/products/4641434-hot-shots-secret-diesel-extreme-fuel-additive-64-oz) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-01*
