THE IMPORTANCE OF FUEL SYSTEM MAINTENANCE FLUIDS

More than likely, you’ve had discussions with your customers about fuel system maintenance and fuel additives in particular. You’ve probably been asked whether they’re really needed and how effective they are. The short answer is: it depends on what’s in them. Even high-quality fuel creates carbon deposits during combustion. Over time, those deposits can build up on engine parts, affecting performance and fuel economy.

To restore performance, the deposits must be removed. While every fuel additive uses a different formula of cleaning agents to accomplish this, the detergents most commonly used by top selling brands are polyisobutene (PIB), polyisobutyleneamine (PIBA) and polyetheramine (PEA). Products using other compounds offer little to no cleaning ability. PIB is typically used in gas treatments and fuel injector/carb cleaners. In high-enough doses, it can prevent new carbon deposits from forming, but it isn’t powerful enough to remove existing deposits and needs to be used with every fill-up. PIBA is typically used in fuel injector cleaners. Unlike PIB, it can remove some existing deposits and has a longer interval between applications. But it’s not hardy enough to survive in the combustion chamber. With temperatures as high as 495 degrees, the combustion chamber is extremely difficult to clean. Only PEA remains stable enough in high heat to remove carbon deposits in this environment.

Other detergents simply burn up without effectively cleaning piston tops, cylinder heads or direct injectors. That’s why any truly effective fuel system cleaner should contain PEA. Gumout Multi-System Tune-Up® uniquely treats the entire fuel system with a scientifically formulated blend of premium cleaning agents, including PEA. But cleaning is only part of the story. Multi-System Tune-Up also includes a wide range of conditioning agents. Antioxidants help stabilize fuel and oil in engines that are used less often, keeping varnish from developing on metal parts. And corrosion inhibitors prevent key engine parts from degrading, helping extend engine life. Multi-System Tune-Up can be used in gas, ethanol and diesel, or poured directly into the crankcase to clean and stabilize oil. It’s built to handle the requirements of modern engine technology, like GDI (gasoline direct injection), turbos and superchargers, and it’s equally effective on engines without those systems, thanks to its advanced ingredients.

Like all Gumout products, Multi-System Tune-Up is thoroughly tested in our labs, in independent labs and in fleet tests. To provide statistical proof of its effectiveness, all of the relevant ASTM tests are performed.
