Pour in one dose of Redex – The size of Redex bottle you have will determine the amount to pour in. A single dose will treat a 50 litre tank Given that the additives I’ve been using are not performance boosters as such, I wasn’t expecting to feel any noticeable differences to my car’s accelerative qualities. If that was the point, Redex has products like its Petrol Power Booster. Alternatively, I could just fill my tank with premium unleaded fuel, which has a higher octane level than regular unleaded and provides extra power. Since May, I’ve been recording my fuel economy every time I fill up the tank – manually noting down the litres added and mileage covered, rather than relying on the car’s trip computer – and adding a dose of Redex to the tank.

They have just started to sell Redex in the filling station in Dalian China where my wife fills up , we do mostly stop start short trips & she has been told to put the additive in for 5 fills that's all . the car is not all that old & has done 40000km's which is nothing I don't think it is a bad thing. As I’ve made clear previously, this isn’t a laboratory test in controlled conditions but rather a real-world trial that gives a decent indication of what any driver can expect in everyday life. As with Cataclean, we often get a lot of questions in our chat box regarding Redex and how best to use it. So we thought we’d write a short article covering the most common questions as well as providing the instructions from the manufacturer. Redex instructions Firstly, if you have an older or higher-mileage car, you are far more likely to see noticeable improvements in performance and fuel economy compared to a newer, lower-mileage vehicle. Given that fuel deposits and debris build up in your engine over time, it makes sense that you’ll notice a greater improvement in an older engine that has seen a few million more fuel explosions than a newer engine. If I’d been running the same test on an older car I am sure I would have seen some more noticeable results, but unfortunately I don’t have an older car to call upon for such a purpose (and buying an old banger to drive for three months didn’t really appeal!) I have used one quarter of it, 125ml, then added about 25 litters of 95 unleaded, I still had about 15 litters in my tank.The principle with the fuel system cleaner additives is that a clean fuel system will perform more efficiently than a clogged fuel system, much like your heart being able to pump blood more freely through clear arteries than clogged ones. Clogged arteries also mean your heart has to work harder and is at greater risk of heart damage, and your engine is no different. Over time, clogged fuel injectors can potentially lead to expensive engine damage. OVERALL: Good product. Performance and emissions difference is noticeable, but don't expect the world. Generally, makes the motor run smoother. Redex makes the engine run smoother. I have made HP/KW tests before and after Redex and there is a noticeable difference. Removes built-up carbon from the underside of the valves. Reduces emissions, tested it on my car before and after before MOT inspection. Redex is fully compatible with E10 fuel and they’ve recently updated their formula to protect against possible corrosion from using E10 fuel, so it can be used in all petrol vehicles. Can Redex be used in a hybrid car? Redex Petrol fuel additives can be used safely with new E10 fuel in E10 compatible cars, as well as with E5. How Much Should I Use?

I’ve just finished a three-month trial of Redex fuel system additives in my Mazda MX-5 to see if I could feel any increase in my car’s performance or measure any significant difference in its fuel economy. It still seemed to choke a bit more at first, but started to perform a bit better a few days later.

Our petrol and diesel fuel system cleaners are supplied in 250ml and 500ml sizes. The smaller 250ml version contains two doses / shots and the 500ml provides 4 shots.It has markings on its side so you know how much to put in, but it's hard to judge once the bottle is upside down. OVERALL: Good product. Performance and emissions difference is noticeable, but don't expect the world. Generally, makes the motor run smoother.

One shot of Redex fuel cleaner is capable of treating a fifty-litre fuel tank, but those who have never used a fuel additive before – or those who own an older car – may wish to use two shots for an intensive clean, particularly during first application. Given that your engine creates dozens of explosions every single second, there’s a lot of combustion going on under your bonnet. With any burning of fuel, there will be deposits and debris that forms. Sometimes it’s obvious, like the ash that forms when you burn a log in a fireplace. Other times, like in your car’s engine, these deposits are microscopic, but the principle is the same. Over time, these deposits build up and affect your ability to keep burning the fuel properly.Keep a look out for our new Petrol System Cleaner coming to stores soon, and look for the E10 logo. My fuel economy figures haven’t shown any changes that could really be attributed to the Redex products. The variation of 3-4mpg above or below the average based on driving conditions and traffic outweighs any potential gain from the products. Again, if you were running a laboratory experiment that directly measured fuel consumption and removed all other variables then you may be able to show an improvement, but it’s nothing really noticeable.
