As Shaun said, the percentage of comments about this product seems like an advertisement and he is absolutely correct. I believe Red-x is an incredible product, but it’s a dangerous product, without understanding the repercussions. If you have an old car that has Carbon build up behind the rings and on the ring lands etc. As well as in the chamber and on the piston crown, because people are to cheap to use the correct octane fuel etc and are running continuously in detonation Providing superior protection and outstanding lubrication, Redex oils contribute to improved engine health, longevity and performance. And because they’re tested in real-world conditions like our innovative fuel additives range, you get the same quality you’ve come to expect from Redex. A drop in oil level can do more damage in a modern engine with a smaller sump – oil spends less 'recovery time' in the sump cooling down and hotter oil will break down and oxidise more rapidly leading to increased wear. Redex 5W-30 is a fully synthetic, Ford-specific engine oil. It’s suitable for most petrol and diesel versions of DuraTec, DuraTorq and Zetec models including those with fuel-injected, multivalve and turbo-charged engines.

Yes, Redex is good for your car. It helps to remove harmful deposits that build up in your fuel system over time, restoring lost performance, improving fuel economy, and reducing emissions. Regular use of Redex can help maintain your vehicle’s performance and keep it running smoothly. How to Clean Diesel Fuel Injectors Part-Synthetic oil is exactly as it sounds – a mixture of synthetic and traditional oil. It’s a step above non-synthetic oil and doesn’t cost as much as premium engine oils, but can’t deliver the same performance as fully-synthetic variants. We noticed slight increases in mileage per tank after the second and third additions of Redex. This of course can’t be definitively put down to the system cleaner, but it certainly didn’t hurt. Since our car is relatively young, the best we can expect is a 2-3% improvement in performance. For older cars, say 10 years or older, you can experience more drastic improvements as the fuel deposits will have had more of a chance to gather. The main difference is that synthetic engine oil has been chemically synthesised in a laboratory to maximise performance, lubrication, and protection. Non-synthetic oil, on the other hand, is a type of refined crude oil that isn’t purified for use in car engines. This oil has a higher viscosity level, which means that it provides slightly better protection in warmer weather than ‘30’ oil.Extended service intervals, smaller capacity sumps, turbo chargers and thinner, synthetic oils can all add up to higher oil usage. The manufacturer may also give an acceptable equivalent ACEA or API specification, though this might be for 'emergency top-up only'.

Redex Advanced 5-in-1 system cleaner is a heavy-duty cleaner while Redex petrol system cleaner is a regular cleaner. Finally, it offers outstanding protection for internal engine components, with long-lasting lubrication reducing the likelihood of wear and corrosion.

How it Works

Just as you wouldn’t leave your car interior or bodywork dirty for months on end, you shouldn’t take liberties with your engine. Fuel economy can be reduced by the deposits which build up on your fuel injectors during combustion. This is a result of the varying fuel qualities available in the UK and the amount of additives they contain. The resulting build-up means that you’ll be paying more for fuel, as your injectors won’t be working as efficiently as they should. The fuel economy results did not show significant differences attributable to the use of Redex fuel system cleaners. As a driver, understanding engine oil grades can help you choose the right oil for your climate, environment, and typical driving conditions. As I outlined in previous reports, the type of fuel additive that I’ve been using is a fuel system cleaner rather than an octanebooster. The goal isn’t to turn regular unleaded into premium unleaded by increasing the car’s octane number, but simplyto give all the tiny pipes and injectors a thorough clean so they can do their thing without being clogged up. Redex System Cleaner is really simple to use. Just add 90ml of the cleaner to your fuel tank every time you refill the tank. If you haven’t used any fuel additives in a while, it’s a good idea to first add a double dose (180ml). This will clean the engine thoroughly before regular use.

Over about 2,000 miles of mainly commuting in three months, my average fuel consumption using the Redex fuel system cleaners was 31.1mpg. My driving circumstances in that time have been a pretty representative example of my usual activities, so superficially it looks like a 1mpg improvement since using Redex.Since leaded petrol was removed from fuelling stations, classic car owners either have to use unleaded or convert their cars to run on a different type of fuel. 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.
