What is carbon engine cleaning and is it worth it?

A well-maintained modern car should be capable of covering six-figure mileages without needing any major attention. But it is reasonable to expect some drop off in performance as a car gets older and components wear. Many garages will recommend carbon cleaning as a way of restoring some of that lost performance, or as a way of helping your car pass the emissions part of the MoT test. But what is engine carbon cleaning, and does it work? Is it just expensive ‘snake oil’ or can it bring tangible benefits to your car?

Why might you need your engine carbon cleaned?

First, let’s look at the reasons an engine might need to be cleared of carbon at all. Petrols and diesels produce power by burning fuel, and this creates sooty exhaust gases. Emissions control devices such as catalysts and diesel particulate filters keep the amount of soot which reaches the atmosphere to a minimum, but there is still some which is deposited on components inside the engine and exhaust system. Vintage cars built before modern oils and fuel technology came about would need a ‘decoke’ every few thousand miles, which involved opening up the engine and physically scraping off the carbon deposits. Thankfully that is no longer the case, but engines can still require a carbon clean - especially (and ironically) those which are fitted with advanced emissions control equipment.
