How much do i put in my tank?** A: I aimed to put in 10ml per litre of fuel. I bought the smaller bottle with built in dosing chamber on it. I'd measure 2 full (35ml) Chambers worth then fill up with fuel (to mix it about) to the brim.. My tank is 70L and was never totally empty, all overdosing does is waste product.. I've moved on to using 'Dipetane' as a diesel additive now.. Doesn't smell bad in the boot of car (unlike this product) and has increased my MPG & in my opinion is a better product **Q: How much would you recommend for a 52l fuel tank in my 2008 volvo c30 1.6d please?** A: Usual dose at 1:1000 (1ml to 1 Litre fuel) to 1:500 (1ml to 0.5 Litre fuel) depending on the quality of fuel and performance increase required. **Q: Is it safe for Audi a6 c7 ultra 2.0 2016 with ad blue?** A: Yes its safe in fact what it it does is it increases the cetane so increases how the diesel expands in the chamber . I use in Mercedes S class . Every 4 tanks I still use premium diesel . I use like this because I'm not doing enough motorway milage . Modern diesel is no good on journeys less than 20 miles so considering petrol . **Q: What is the difference between this product and the cetane booster that you sell with the brown label** A: 1. Hydra Cetane Booster has extra lubricant. Hydra 2-EHN does not have extra lubricant, as it is designed to be added to homemade bio-diesel which does not require extra lubrication --- ## 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.com.om/products/67516460-hydra-ehn-99](https://www.desertcart.com.om/products/67516460-hydra-ehn-99) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-10-15*
