Carbon Buildup

Fuel injectors increase fuel efficiency and engine response times by delivering a fine mist of fuel right at the engine’s intake valves. This allows fuel to burn more easily, increasing the engine’s response times while reducing the amount of fuel used.

Port fuel injectors spray fuel in the intake port area where it flows past the intake valve into the combustion chamber.

Direct injectors have the tip positioned directly in the combustion chamber and spray fuel into the combustion chamber, bypassing the intake valve. This design allows the engine to have even better fuel economy.

Carbon deposits can clog fuel injectors, turning the fuel pattern into a stream instead of a mist. As a result, less fuel is delivered to the combustion chamber and the fuel that does enter the chamber burns less efficiently.

Port fuel injectors can be cleaned using a detergent called PIBA (polyisobutylene-amine). But GDI/direct injectors are harder to clean. They require P.E.A. (polyether-amine), a specialized detergent that’s strong enough to survive the heat of a combustion chamber. Check individual product details for detergents used. Port fuel injectors spray fuel in the intake port area where it flows past the intake valve into the combustion chamber. Direct injectors have the tip positioned directly in the combustion chamber and spray fuel into the combustion chamber by-passing the intake valve. This design allows the engine to have even better fuel economy.

Clogged Fuel Injector

Clean Fuel Injector

Performance Issues

Hard starts, power loss, rough idle, slow acceleration, lower fuel economy, increased emissions.

Solution

Gumout® fuel additives use a variety of detergents to fight carbon buildup in fuel injectors. These detergents bond to carbon particles on injectors and disperse them to restore performance. They also bond to the surface of the nozzle, helping prevent further carbon buildup.

Carbon Buildup

Carbon buildup on intake valves, before and after.

Fuel and carbon deposits on the valves negatively affect acceleration, causing hesitation. And when carbon deposits build up on the base of valves, they act like sponges, soaking up fuel. This means less fuel than expected enters the combustion chamber, disrupting the fuel-air mix and hurting performance

Performance Issues

Rough idle, hesitation, surging, increased emissions.

Solution

The detergents in Gumout fuel additives bond to carbon deposits on intake valves and ports to disperse them, restoring performance. They also bond to the metal surfaces of the valves and ports to help prevent future carbon buildup.

Carbon Buildup

Engines generate power by igniting a precise fuel-air mixture in the combustion chamber. The fuel and air are heated through compression, then ignited with a spark plug for a controlled explosion. Carbon deposits on piston tops and cylinder heads trap heat, creating hot spots that can cause fuel to ignite prematurely. These uncontrolled ignitions create higher pressures than normal combustion and can cause knocking, pinging and, in extreme conditions, engine damage.

Performance Issues

Preignition, increased emissions, engine failure.

Solution

Gumout® fuel additives use P.E.A. (polyether-amine) to remove deposits from difficult-to-clean parts like combustion chambers, piston tops and cylinder heads. While most detergents burn up in the heat of the combustion chamber, P.E.A. remains stable, even at 495° F. It bonds to carbon deposits and removes them from the fuel system. P.E.A. also bonds to metal surfaces to prevent future buildup.

These deposits negatively affect the flow of the atomized air-fuel mixture as they enter into the combustion chamber. This can cause inefficient combustion leading to reduced engine performance.

Performance Issues

Power loss, lower fuel economy.

Solution

Gumout® fuel additives that have P.E.A. (polyether-amine) in their formulas help to remove deposits from difficult-to-clean cylinder heads. While most detergents burn up in the heat of the combustion chamber, P.E.A. remains stable, even at 495° F. It bonds to carbon deposits and removes them from the fuel system. P.E.A. also bonds to cylinder head surfaces to help prevent future buildup.

When sheared past its limitations, oil will not deliver the lubrication needed to keep the engine from overheating or potentially causing complete failure. The oil system literally and figuratively keeps things running smoothly. Metal engine parts interacting with each other work more efficiently when properly lubricated with clean oil. Oil filters can only do so much, so when the extreme conditions of the engine take their toll on oil, it can lose viscosity, decreasing its ability to lubricate. Dirty oil can cause sludge and acid buildup, which can damage key engine parts. When sheared past its limitations, oil will not deliver the lubrication to keep the engine from overheating or potentially completely failing.

Performance Issues

Dirty oil can cause sludge build up that can reduce performance and increase wear. Acid build up leads to corrosion that can damage engine parts. The second paragraph needs to be tailored to MSTU not high mileage oil treatment which we haven’t sold in years. So detergency and anti-corrosion should be the main talking points – clean oil lubricates better reducing heat that can cause parts damage and reduced sludge allows parts to move more freely increasing performance. Cleaning agents found in MSTU help keep engine oil and parts clean to unleash your engines full potential and corrosion inhibitors ensure that you maximize engine life.

Solution

Gumout High Mileage Oil Treatment removes sludge and deposits using specialized cleaning agents to help restore performance and extend the life of engine parts. Gumout additives also recondition worn seals to prevent leaks, while viscosity improvers work to increase oil pressure, reducing blow-by and oil consumption. To protect the valve train from wear and corrosion, the ZDDP (zinc dialkyl dithiophosphate) in Gumout adheres to metal surfaces, forming a protective layer against friction and corrosion to keep the engine running longer and smoother.

Performance Issues

Humidity and condensation can also cause water to build up in the fuel system over time. This effect is amplified by gasoline blended with ethanol, which attracts water, especially in hot, humid climates. In colder climates, water makes any gasoline in the fuel line more susceptible to freezing and damaging engine parts. Ice in the fuel line can block fuel flow, preventing the engine from running. The detergents in Gumout remove water from the fuel system, improving fuel quality and performance. Diesel fuels can also lead to issues in colder climates. Unlike gasoline, ultra-low sulfur diesel fuel has a relatively high pour point. This is due to naturally occurring waxes in the fuel that start to crystalize as they dip below 20°F, depending on the specific fuel. When the waxes start to freeze, it can cause the fuel to gel.

Solution

In engines that aren’t used frequently, both gasoline and diesel fuel can deteriorate, leaving behind varnish and gummy carbon residue. Gumout Multi-System Tune-Up stabilizes fuel and oil using an antioxidant to stop deterioration and extend the life of fuel, allowing engines to start easier and run smoother after sitting unused. The detergents in Gumout remove water from the fuel system, improving fuel quality and performance. In addition, Gumout Multi-System Tune-Up contains isopropyl alcohol, which grabs even more water, scavenging condensation to keep it from freezing in winter or corroding metal engine parts. Gumout diesel additives use an anti-gel compound to counteract the effects of crystallization and improve cold flow.
