What is top tier gasoline?

Since 1995, all gas in the US is required by law to contain a minimum quantity of deposit control additives to help keep engine components clean, resulting in lower emissions, improved fuel economy and better power in the vehicle.

But in 2004, as engines had already evolved significantly, six automakers (GM, BMW, Toyota, Honda, VW, and Audi) began to recommend higher levels of additive. They felt the current EPA minimum deposit control requirements did not ensure optimal engine performance, especially given their ever-advancing engine designs. These automakers came up with a new standard for gasoline with greater deposit control performance. This higher quality gasoline standard is known as TOP TIER.

How gasoline direct injection engines work.

The gasoline direct injection engine is part of a long history of sophisticated and innovative evolutions in the industry geared toward achieving better fuel economy, lowering emissions, and increasing engine power. As an alternative to the port fuel injector, which delivers fuel past the cylinder’s intake valve, the direct injection engine has fuel injectors that spray fuel directly into the combustion chamber.

These complex new technologies require fuels to evolve at a similar pace. The right combination of advanced fuel additives are critical in keeping the direct injection engine clean and efficient — delivering the right quantity of fuel, at the right time, in the right position in the cylinder.

How friction modifiers work.

About a quarter of all gasoline burned is to overcome friction, caused mostly by the piston movement in the engine. Reducing this metal to metal friction helps engines run more efficiently. Quality gasoline, containing friction modifier additives, offer some real value.

Gasoline with friction modifiers helps improve fuel economy, and when vehicles burn less fuel, they produce less emissions. What’s more, friction modifiers can actually even improve fuel economy to levels above when the car was new. By reducing friction in the engine, vehicles run more economically — like new, and in some cases, even better than new.

How deposit control additives work.

Engine deposits from low quality gasoline can occur in several critical areas and impair the fuel economy, starting, driving, emissions and performance of our vehicles. That’s why deposit control additives (often referred to as detergents) are so important ­ helping to maintain a clean engine to meet fuel economy and emissions requirements.

Gasoline deposit control additives are as critical as a mechanic in keeping today’s sophisticated cars running as they should.

How gasoline additives make your engine work better.

Passenger vehicles continuously become more sophisticated to meet changing emissions regulations, improve fuel economy, and meet consumer performance demands. Engines become more complicated with modern engine designs.

It’s no surprise that today’s more sophisticated components require more sophisticated fuels. All gasoline is not the same. Not even close, actually. The quality of gasolines on the market today can vary dramatically. A high quality gasoline truly does deliver very real and measurable benefits, and it this through the science of fuel additives. Fuel additives are key to enabling the continued advancements in modern engine components.
