Regular use reduces emissions by up to 60%, improves fuel economy, restores engine performance, and helps prevent MOT failures. Designed for easy use, add 500ml per 15 litres of fuel every three months to maintain optimal vehicle health and efficiency. ## Description Carbon build-up is a natural by-product of combustion and it can cause problems in vehicles, which can result in unnecessary down-time and worse performance. Cataclean can prevent this. Added to the fuel tank, Cataclean does not alter the fuel composition and is carried with the fuel through the fuel system, cleaning carbon build-up as it comes into contact with it. Cataclean’s cleaning formulation can clean everything the fuel comes into contact with including the fuel tank, fuel injectors, diesel particulate filters (DPF), catalytic converters (CAT), exhaust gas recirculation valves (EGR), oxygen sensors, combustion chambers & intake valves. Upon combustion in the combustion chamber, Cataclean creates an acidic vapour containing carboxylic acids that continues through the system to clean carbon from the exhaust including the catalytic converter and DPF/PPF. Cataclean is an 8 in 1 complete fuel and exhaust system cleaner and works to clean the following: Fuel Tank & Lines Fuel Injectors Combustion Chamber Intake Valves EGR (Exhaust Gas Recirculation) Valves Oxygen Sensors Catalytic Converter Diesel/Petrol Particulate (DPF/PPF) Filter Ensuring the fuel and exhaust system is clean can produce benefits such as: Improves Fuel Economy Reduces Emissions Restores Performance A cleaner fuel and exhaust system can also prolong the life of vehicle components. Use every 3 months for optimum results. Directions of use: Remove seal before emptying entire contents of one bottle of Cataclean Petrol into fuel tank. Then drive for at least 15 minutes and refuel when necessary. Recommended ratio of one 500ml bottle of Cataclean Petrol to approximately 15 litres of fuel.

He had more than a quarter of a tank of diesel so ended up having to order a couple but it was well worth it because it fixed the problem. If you'd like any more information let me know and I'll get my son to msg you. **Q: Whats the quantity in ml per bottle ?** A: 500 **Q: Are these 450ml bottles or the 500ml bottlles** A: It’s 500 ml **Q: Are these 450ml bottles or the 500ml bottlles** A: When I bought mine last year they were 500ml bottles ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well. *by P***. on 12 July 2025* It worked a treat in my truck follow the guidelines on the back of the bottle..👍 ### ⭐⭐⭐⭐⭐ Good *by A***M on 3 September 2025* Good quality ### ⭐⭐⭐⭐⭐ It Cleared it!! *by D***R on 19 June 2025* Does the job, even cleared management light for DPF depending on how bad it is may have to do a couple of times. ## Frequently Bought Together - Cataclean Diesel | Complete Fuel & Exhaust Cleaner | Catalytic Converter, Valve & Injector Cleaner | Fuel Additive Formulated for Performance & Fuel Efficiency | Pre MOT Emissions Reducer | 4 x 500ml - Cataclean Petrol | Complete Fuel & Exhaust Cleaner | Catalytic Converter, Valve & Injector Cleaner | Fuel Additive Formulated for Performance & Fuel Efficiency | Pre MOT Emissions Reducer | 4 x 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.hr/products/48172911-cataclean-diesel-complete-fuel-and-exhaust-cleaner-catalytic-converter-valve](https://www.desertcart.hr/products/48172911-cataclean-diesel-complete-fuel-and-exhaust-cleaner-catalytic-converter-valve) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-09*
