Amsoil Fuel Additive Improves Vehicle Performance

Amsoil fuel additives improves vehicle performance

Unlike all-in-one additives, Amsoil fuel additives are formulated to provide nearly immediate results

When vehicle performance and fuel economy decline, many motorists turn to fuel additives to solve the problem. There are several brands available, and most promise  some combination of the following benefits:

  • Increased fuel economy
  • Smoother engine operation
  • Reduced emissions
  • Maximum horsepower oil


While motorists expect fuel additives to deliver immediate results, typical “all-in-one” additives require the use of several tanks of fuel before providing any noticeable performance improvement. Most people don’t want to wait that long or commit to buying several bottles fuel additive.

Engine condition plays a vital role in additive performance

To understand why additive performance varies, you should understand why your engine may need a fuel additive in the first place.PI For optimum fuel efficiency and lower emissions, fuel must first be atomized into fineness prior to combustion. Over time, injector deposits reduce irregular spray patterns with streams of gasoline that reduce performance, while intake valve deposits also decrease efficiency. Today’s injectors are highly engineered to tight tolerances, and even minute deposits interfere with the sprayed pattern and reduce power and fuel economy. The problem is especially pronounced newer high-pressure common rail  (HPCR) diesel engines and direct injection engines that locate injectors in the combustion chamber, exposed to intense heat.

Additive concentration matters

Fuel additives help clean engine deposits, restore lost power and improve fuel economy. However, most additives don’t contain sufficient concentration of cleaning agents and other performance-improving chemicals to provide the nearly immediate results expected. Instead, after using the additive with every tank of fuel, over some period of time-possibly weeks to months-you may experience a slight uptick in power, fuel economy or drivability. Continued use with every tank of fuel maintains engine performance.

Amsoil fuel additives are different. As performance concentrates, they boast potent formulas designed to provide nearly immediate results. Amsoil PI is does an excellent job cleaning deposits to improve the fuel economy up to 5.7% and an average of 2.3%.

Amsoil applies the same philosophy to all Amsoil fuel additives.
