For example, a 60L tank would require 60ml. **Q: can anyone tell me the mpg increase they got using this if any ?** A: I have been using this now for 8 years. My MPG has increased from 23 to 28 with a 1996 Fiat 2.5 in a 3,400 kg motorhome. That is equivalent to about 20% improvement one free gallon for every five. The first couple of doses saves the price of the complete bottle. You are effectively paid to use it. Performance is also enhanced with down gearchanges nearer the top of hills or not at all. Fuel consumption is calculated on full-tank to empty-tank miles. I can achieve 50MPH by the time I reach the end of a motorway downhill slip-way where before it would be about 40. If you're sceptical, try it - I was but I'm glad I overcame that. I've just ordered another bottle. I've just bought a Fiat Doblo 1.9 diesel - I'll try it in that next. --- ## 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.pt/products/50719139-archoil-ar6900-d-max-advanced-diesel-additive-concentrate-500ml](https://www.desertcart.pt/products/50719139-archoil-ar6900-d-max-advanced-diesel-additive-concentrate-500ml) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-21*
