Effects: cleaner exhaust; engine running smoother, more power and more economical. A dirty engine does not run the way the electronics are adjusted for. Cleaning may help, depending on how the engine got polluted. **Q: can i fill new fuel filter with pro line and run? rest in fuel tank** A: Don't think I would try that get just as good results from just running it from the tank with the fuel I also purchased another from product called diesel power blast it's an injector cleaner and fuel stabiliser only need to add 10ml to Β£30 of fuel and that these both do a great job Hope this helps . **Q: Do you add the whole 500ml to 1/4 of a tank drive a few miles then top up tank? Or just add to a 1/4 of a tank and top up to full and use as normal** A: The 500ml will treat up to 70litres; I added it to a near full tank because that's around 70-75 litres for my car. It will mix in the fuel very quickly just as you drive around. There is no harm in adding it at the fuel station and then immediately filling up - that will certainly mix it! **Q: Does this clean dpf system** A: It helps BUT, if you have issues with your DPF it’s better to go to a professional for that. There is no fuel additive that can fully clean a DPF. ## Frequently Bought Together - Liqui Moly 5156 Pro-Line Diesel System Cleaner 500ml - LIQUI MOLY Cera Tec 3721 I Ceramic Wear & Tear Protection for Petrol & Diesel Engines I Smoother Engine Performance, Less Friction & Lower Fuel Consumption I Ceramic Additive 300 ml Pack of 1 - LIQUI MOLY Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2427 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/48193114-5156-pro-line-diesel-system-cleaner-500ml](https://www.desertcart.gr/products/48193114-5156-pro-line-diesel-system-cleaner-500ml) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-05*
