I always use DPF after fillup and it works magic. You can either use this or next time fillup V-Power **Q: Hi I have never Tryed the product and I don't have a clue how much to put in and all so will it cause engine issues in the future.** A: Ok so redex is good for the car truck van etc ... it will help clean the system out and also increases mpg for you. On the bottle it tells you how much to put in . 2 Shot bottle is roughly 1/2 bottle per tank depending on your tank . Me ... I do full bottle to 1 tank from empty. but that's on a ford kuga 2ltr diesel. Never had any issues . Again if unsure go by what's on the bottle. Some av markings on for you to go by. You mite also need to use your emergency feul spout depending on yr car. I can recommend this product 100% **Q: How many miles between doses** A: I give it a shot every other refill as I do a very low mileage which is not good for the car. They do say you can use it each fill up, or as I used to when I drove a lot, 4 times a year. Depends on your car, how old it is, kind of driving, motorway or local. The instructions are on the bottle, but if Google around for your own needs is best. **Q: I’ve had dpf issues. i’ve done regen and some of the cleaner. if i use this diesel cleaner could it make the dpf worse? will that make it build up aga** A: Firstly this diesel cleaner will help clean up the diesel injectors so you get good combustion and more miles to the gallon. If you have dpf problems it is generally because you have been running around town doing short journeys and the dpf is getting blocked, the regen action dumps fuel into the dpf to get it hotter than normal to burn out the blockage. The dpf cleaner is a catalyist which combines with the blockage and drops its burning temp so it self cleans as you drive normally . I use the diesel cleaner (1/2 bottle) in the tank with the low alarm on and go for a 10 mile drive at a good speed twice a year. Do this then half fill tank with the dpf cleaner and drive normally down to 1/4 tank, then go on the motorway and boot it for a few miles. Should sort it out if not too blocked ## Customer Reviews ### ⭐⭐⭐⭐⭐ Booster *by K***F on 9 June 2026* Booster diesel Made my car do 150 mph in a mile ### ⭐⭐⭐⭐ arrived on time *by R***N on 6 March 2023* good stuff best i have used yet on my astra cdti ### ⭐⭐⭐⭐⭐ Redex Diesel Cetane Booster. *by M***Y on 17 March 2026* Great product, does exactly what it says on the bottle. ## Frequently Bought Together - Redex Diesel Booster, Diesel Additives To Boost Cetane Number, Maximise Performance & Increase Fuel Economy With Redex Diesel Fuel Additive, Boost Diesel Engine Performance & Improve Power, 250ml - Redex DPF Cleaner Diesel, DPF Diesel Particulate Filter Cleaner To Clear Soot Blockages Quickly & Avoid Costly Repairs, Hassle-Free DPF Cleaner To Prevent Clogging & Reduce Emissions, 250ml --- ## 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.jp/products/365227232-redex-diesel-booster-diesel-additives-to-boost-cetane-number-maximise](https://www.desertcart.jp/products/365227232-redex-diesel-booster-diesel-additives-to-boost-cetane-number-maximise) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-01*
