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. ## 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.jp/products/453477869-hot-shots-secret-diesel-extreme-1-gallon-diesel-fuel-additive](https://www.desertcart.jp/products/453477869-hot-shots-secret-diesel-extreme-1-gallon-diesel-fuel-additive) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-05*
