The invention of the internal combustion engine as we know it was a turning point for the world, leading to automobiles and a form of fast personal transportation unimaginable to most. Throughout history enterprising people have designed engines of one form or another to make work and movement easier, but it was when commercial drilling of petrol began in the 1850s that the internal combustion engine became widely used.

Since the early days of fuel combustion, drivers and engineers have known that certain additives can help engines to work better. Deposits build up inside the engine and on carburettors, or these days on fuel injectors, leading to an inefficient use of fuel. Other problems like loss of power and increased emissions can be helped by using the right additives.

This is why Redex was set up all the way back in 1922, to help keep engines running for longer. Over the years Redex became established as part of a good car maintenance routine – particularly during the 1970s  when you could buy a shot of Redex at filling stations. When you filled your car you could ask for a “penny a shot”, and the Redex would be poured from a red can directly into your tank to keep your engine healthy.

Throughout the second half of the twentieth century, it became clear that leaded fuels were contributing to serious health problems and adding to pollution. Catalytic converters were added to cars, and in 1986 unleaded petrol was introduced in the UK. By 2000, leaded petrol could no longer be purchased at the pump. For some, this created a worry. If you had an older car which was built to take leaded petrol, could you safely use unleaded? Redex again found a solution to help those with older cars to care for their engines – Redex Lead Replacement.

Over the years, Redex had developed products to respond to the changes in engines and car technology. This year, we’ve combined our Treatment and Injector Cleaner products into one easy to use fuel additive – System Cleaner for diesel or petrol. It draws on Redex’s decades of experience in engine care, to create one simple additive which helps you to save fuel and keep driving for longer, just as we always have done.
