Dipetane Fuel Treatment 5 Litre

For anyone running a van, truck, tractor or multiple vehicles — the 5 litre bottle is the smarter buy. It treats up to 1,000 litres of fuel, cuts your running costs, and keeps your engines cleaner for longer. One container, serious long-term savings.

What Dipetane Does

Dipetane is a 100% hydrocarbon fuel treatment — not an additive, not a chemical blend. It contains nothing that isn't already naturally present in fuel. At a molecular level, it improves the way fuel burns, releasing more energy from every litre and leaving far less carbon behind in your engine.

• Up to 10% better fuel economy — cleaner combustion means fewer fill-ups
• Cleans DPFs, injectors, valves, pistons and EGR valves — and keeps them clean with continued use
• Up to 25% lower emissions — less CO₂, CO and NOx from every engine you run
• Up to 50% less exhaust smoke — important for passing emission tests
• Longer engine life — less carbon build-up means less wear on injectors and pumps
• Works on all liquid hydrocarbon fuels — petrol, diesel, kerosene, heating oil and biodiesel
• Does not void warranties — fully compliant with EU and British fuel standards

The Smart Choice for Regular Users

The 5 litre bottle gives you better value per litre of fuel treated and is ideal for fleet operators, farmers, hauliers, and anyone who covers serious mileage. It also works in domestic oil heating boilers — one product, multiple uses across your whole operation.

How to Use It

Add Dipetane directly to your tank before filling up. The mix ratio is 1:200 — 1 litre of Dipetane to every 200 litres of fuel. It's self-mixing, no blending required. At this ratio, a 5 litre bottle treats a full 1,000 litres of fuel.

Irish manufactured. Dipetane is made in Kilcoole, Co. Wicklow — independently tested across cars, vans, trucks, buses, tractors and domestic boilers, with proven results over decades of real-world use.
