Eco-friendly High Octane Gasoline
ENEOS Eco-friendly High Octane Gasoline
ENEOS has developed an eco-friendly, high octane gasoline that offers outstanding detergency and is sulfur-free*1 (sulfur content: less than 10 ppm).
ENEOS High Octane Gasoline is formulated with detergents to help keep engines clean. Regular fill-ups with ENEOS High Octane Gasoline will keep intake valves much freer of deposits than with regular gasoline. Your car will accelerate better and also produce lower levels of harmful emissions, which benefits the environment.
- *1Definition of "sulfur-free"
Fuels are considered sulfur-free if they have a sulfur content of 10 ppm (parts per million) or less. The early adoption of new automotive technologies and the elimination of sulfur from fuels are steps that must be taken if we are to further reduce harmful emissions, CO2 included, on the way to realizing zero-emission vehicles.
What does it mean for an engine?
A gasoline with good detergency helps keep deposits from forming on the intake valves and other components of the engine's intake system. Gasoline can get stuck on intake valves with heavy deposits, which can lead to combustion problems. Preventing these deposits from forming helps the engine continue to perform as it should. (Fig. 1)

Controlling deposits on intake valves (Fig. 2)
In a test we developed to evaluate a fuel's ability to keep intake valves clean*2, our high octane gasoline was much better at controlling deposits than a regular gasoline.

The Sulfur-free Promise
A proactive approach to sulfur content regulations
Driven by a need for more eco-friendly automotive fuels, countries around the world have enacted laws restricting the sulfur content of gasoline (Table 1). Laws went into effect limiting sulfur content to 10 ppm in Japan in 2008 and the EU in 2009, marking the arrival of what is recognized as sulfur-free gasoline.
We were ahead of the curve where these laws were concerned. In fact, ENEOS high octane gasoline has met the definition of sulfur-free since 2002.
Table 1 - Restrictions on sulfur content of gasoline in Japan, the U.S., and Europe
|Japan||100 ppm or less||50 ppm or less||10 ppm or less|
|USA||Federal||1000 ppm or less||30 ppm or less||10 ppm or less by 2020|
|California||30 ppm or less||15 ppm or less|
|EU||150 ppm or less||50 ppm or less||10 ppm or less|
