Ideal for ULSD, biodiesel, and stored fuels, it ensures reliable engine performance and longevity with a precise 100ml per 100L dosing. ## Description A multifunction diesel additive blended in the UK to counteract the problems of using ULSD, Biodiesel and storing fuel. DFC is similar to the additives used in premium fuels offered by the oil majors on the forecourts. It has a Cetene improver, a lubricity improver and a detergent specifically to keep the fuel system clean. Additionally, particularly in Marine, it is also necessary for the additive to help against the problems with stored fuel so an antioxidant and biocide is also added to the blend. Designed for continuous use every time you fill the tank. Dose rate is 100ml per 100 Litres Review: Superb product - This is a superb product, I use it every time I fill my Narrowboat, protects the engine and Eberspacher heating system, not cheap but far cheaper than a major breakdown and fuel system clean.

Run for 30 minutes or so and heard engine getting quieter and smoother. It's now running like a top through all speeds without the miss. Bought enough for 5 top ups so worth the investment. ## Frequently Bought Together - Marine 16 Diesel Treatment Diesel Fuel Complete DFC, 100ml, 500ml, 1 Litre - Marine 16 Diesel Bug Treatment - 100ml - Marine 16 Diesel Bug Treatment: 500ml --- ## 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.tn/products/65412982-marine-16-diesel-treatment-diesel-fuel-complete-dfc-100ml-500ml](https://www.desertcart.tn/products/65412982-marine-16-diesel-treatment-diesel-fuel-complete-dfc-100ml-500ml) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
