Started using EHN-99 and over the next 1000 miles I averaged 55.3mpg. Same 40 mile commuter route every day, similar speeds, weather and temperatures... vehicle runs smoother and can change up gear sooner without struggling. Only dropped a star as the dispensation method is messy and inaccurate. ## Frequently Bought Together - HYDRA EHN-99, 2-Ethylhexyl-Nitrate 99% Pure 2 EHN Performance Enhancer Cetane Booster Diesel Treatment Additive, 1L Treats up to 1000L. - HYDRA DPB-100 Diesel Power Blast - Diesel Fuel System Cleaner | Diesel Injector Cleaner with Diesel Fuel Additive | 1 litre treats 1,000L - Hydra PIC-24 Petrol Injector Cleaner and Carb Cleaner Additive, 500ml Treats 500 litres, With Petrol Cleaner you get more Petrol Power with Octane Booster Removes Deposits Improves Combustion --- ## 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.ae/products/52808641-ehn-99-2-ethylhexyl-nitrate-99-pure-2-ehn-performance](https://www.desertcart.ae/products/52808641-ehn-99-2-ethylhexyl-nitrate-99-pure-2-ehn-performance) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-09-18*
