How Effective is the Fuel Injector Cleaner You Put in Your Gas Tank?
There's a common question among car enthusiasts and owners: is fuel injector cleaner effective when added to your gas tank? Of course, seafoam has been a trusted name for quite some time. However, AMSOIL Performance Improver (PI) has received some impressive accolades and results.
The Role of Pour-in Cleaners
Pour-in injector cleaners, like AMSOIL Performance Improver, are designed to tackle a wide range of issues, such as gum and varnish buildup in fuel injectors. These products work by enhancing the engine's combustion, thereby providing a cleaner burn. Just a few gallons of cleaner can make a significant difference. For instance, using a half tank, or approximately 8 gallons, to a bottle is often sufficient for noticeable results. Many drivers find that this method works well and relies on its consistent effectiveness.
Comparing Products
Seafoam, while popular, may not be as frequent a choice for all mechanics and techs. It can be used for induction cleaning but is only recommended for periodic use, such as every 50, 000 miles. Despite its reputation, it may not be the most ideal choice for long-term use, especially if you have a vehicle nearing 100, 000 miles.
AMSOIL Performance Improver (PI) stands out for its comprehensive cleaning capabilities. Beyond just the fuel injectors, PI can clean the top of pistons and the combustion chamber, making it a more all-encompassing solution. This dual-action cleaner works within the fuel system and directly on the injectors, addressing gum and varnish more effectively than some single-purpose products.
Understanding the Need for Clean Fuel Systems
Modern fuel systems, though advanced, can still suffer from degradation over time. This is due to the blend of components in today's gasolines. Many consider lubricity as a key benefit, but it has been diminished since the removal of lead from fuel. When combined with ethanol (ethyl alcohol), which has the capacity to capture moisture, fuel systems are more prone to corrosion and buildup. This is a concern whether it's in engine fuel or medical settings. Water in the fuel can lead to corrosion and other issues, both for the fuel system and the injectors themselves.
Expert Opinions on Additives
Experts suggest that while additives can help, they may not be necessary. Gasoline producers already blend a variety of additives into their fuel to keep the system clean. Adding more can lead to unnecessary expenses and, in some cases, diminishing returns. A tech with 30 years of experience doesn't recommend using such products, citing that fuel injectors rarely become gummed up. Carbon buildup is a concern with carburetors, where the fuel is much less atomized and the vacuum system allows for precise control. However, modern fuel systems, with their high-pressure fuel rails and precise injection, are already designed to minimize such issues.
There's a school of thought that injectors getting gummed up is a rare occurrence. In carbureted engines, the fuel is less atomized, and the vacuum system allows for controlled fuel intake. With modern fuel injection systems, however, the fuel pump maintains pressure throughout, and the injectors operate in a specific pulse sequence, pushing fuel out forcefully. As a result, gum and varnish are less of a concern, making the use of injectors cleaner and more efficient.
Conclusion
The effectiveness of fuel injector cleaners depends largely on the specific product you choose. While seafoam or AMSOIL Performance Improver may provide acceptable results, the choice ultimately depends on your specific needs and the expert advice of seasoned mechanics. With the right product and a thorough understanding of how modern fuel systems operate, you can maintain your engine's health without excessive use of such additives.
