I took the plunge and bought some of this product. I have a thirsty 2.5litre 4x4 and tow a twin axle caravan. The only painful thing has been watching the fuel gauge move downwards quickly! After adding the recommended amount of this product to my fuel tank - my mpg has increased from 23mpg to 27mpg. The proof is in the pudding & l am pleased l purchased this cetane booster. With the increase of 4mpg - this improvement clearly offsets the costs of this product. Just be careful you don't overdo the amount you add to a tank otherwise this will not be cost effective. ## Frequently Bought Together - HYDRA EHN-99, 2-Ethylhexyl-Nitrate 99% Pure 2 EHN Performance Enhancer Cetane Booster Diesel Treatment Additive 2x 1L Treats up to 2000L - HYDRA DPB-100 Diesel Power Blast - Diesel Fuel System Cleaner | Diesel Injector Cleaner with Diesel Fuel Additive | 1 litre treats 1,000L - LIQUI MOLY Cera Tec 3721 I Ceramic Wear & Tear Protection for Petrol & Diesel Engines I Smoother Engine Performance, Less Friction & Lower Fuel Consumption I Ceramic Additive 300 ml Pack of 1 --- ## 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.co.uk/products/79550119-ehn-99-2-ethylhexyl-nitrate-99-pure-2-ehn-performance](https://www.desertcart.co.uk/products/79550119-ehn-99-2-ethylhexyl-nitrate-99-pure-2-ehn-performance) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-04*
