The benefits extend beyond saving you money on fuel, though. This reduction of harmful emissions could mean your vehicle is a step closer to passing its MOT, meaning even less money is spent on repairs to make it roadworthy. Redex 5W-30, is a fully synthetic formula that lasts longer between oil changes, so you don’t have to change it as often. This can help save money and reduce oil waste which is better for the environment. How it Works More and more often, these are very specialised 'long life' oils designed to support very long intervals between services. 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. Later specification oils are usually, but not always, suitable for older cars, while older specification oils shouldn’t be used in newer cars.

At Redex, we only manufacture fully synthetic motor oil because we believe it provides the best protection for your engine. Find out more about the pros and cons of fully synthetic oil below. Redex fuel additives aim to give a clean fuel system that performs more efficiently, leading to better fuel economy and performance. We’ll be adding Redex to our Evoque every time we buy fuel for 3 months, and posting updates about how it’s working throughout. Most modern engine oils are what we call multi-grade oils. They’re designed to offer optimal engine protection in both summer and winter driving conditions, so drivers don’t have to change engine oil at different times of year. 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

Not all engines are the same, so it shouldn't be a surprise that oils aren't the same either. The specification is another way that engine oils differ. Redex 5W-30 for VW, BMW, MB, Porsche protects your engine from corrosion, wear, and extreme temperatures. Its fully synthetic formula helps to maximise lubrication and protection, giving your engine exactly what it needs to operate safely and efficiently.

Finally, it offers outstanding protection for internal engine components, with long-lasting lubrication reducing the likelihood of wear and corrosion. We’ve been testing Redex System Cleaner for two months now. Our 2.2-litre Diesel Range Rover Evoque has been having the Redex treatment, and is a lot better off for it. The Benefits of a System Clean

Your car deserves the best, so make sure you always use a premium engine oil as part of its annual service.

Whether you drive a petrol or diesel car, the process of adding Redex fuel additives is just the same. We’ve made it easy to add the right dose to your car in a matter of seconds, so you can benefit from improved engine health and performance without any complex additional maintenance.

This oil has a higher viscosity level, which means that it provides slightly better protection in warmer weather than ‘30’ oil. The same as above, the cold temperature rating of this oil is -25°C. The difference between the two sits in the number after the ‘W’.
