What You'll Learn
NASCAR cars use Sunoco Green E15 fuel
The use of Sunoco Green E15 in NASCAR reflects a transition to unleaded fuel, which began in the 1990s with Formula One racing cars. NASCAR initiated experimentation with unleaded fuel in 1998 and started transitioning the national series to unleaded fuel in 2006, completing the switch in February 2007. This change was influenced by elevated blood lead levels detected in NASCAR team members, as leaded fuel contains tetraethyllead (TEL), a fuel additive that boosts octane ratings.
The switch to unleaded fuel in NASCAR has had positive impacts beyond the tracks. After the transition, children living near racetracks demonstrated significant improvements in academic performance compared to previous cohorts. These findings highlight the potential health and environmental benefits of reducing exposure to leaded fuel.
Sunoco, as the official fuel partner of NASCAR, provides specialised fuel that meets the demands of high-performance drivers and complies with stringent vehicle emissions requirements. The fuel's enhanced detergency helps keep engines clean and ensures NASCAR vehicles meet tight emissions standards. Sunoco's expertise in fuel delivery and regulatory compliance further contributes to their longstanding partnership with NASCAR.

NASCAR switched from leaded to unleaded fuel in 2007
NASCAR cars use a specialized type of fuel known as Sunoco Green E15, which is a 98 octane, unleaded fuel blend specifically engineered for high-performance engines and race cars. NASCAR made a significant switch in the type of fuel used in its races back in 2007, opting for unleaded fuel instead of leaded fuel. This decision marked a notable shift in the organization's choice of fuel and had far-reaching implications for the communities surrounding NASCAR racetracks.
The switch to unleaded fuel by NASCAR in 2007 was a pivotal moment, driven by the growing awareness of the health risks associated with lead exposure. Leaded fuel had been a concern for environmental groups, and the Environmental Protection Agency had issued warnings about the potential health hazards it posed to residents, fuel attendants, racing crew members, staff, and spectators in the vicinity of racetracks. Doctors had even detected excess lead in the blood of NASCAR crew members during the leaded fuel era.
The deleading of NASCAR's fuel attracted the attention of researchers, who seized the opportunity to study the impact of this change on nearby communities. One notable study focused on schools near two prominent Florida speedways: Daytona and Homestead. Researchers examined academic performance before and after NASCAR's switch to unleaded fuel. They found that test scores in these schools showed a consistent upward trend after 2007, indicating that the elimination of leaded fuel played a positive role in student achievement.
The findings of the racetrack studies reinforced the well-established understanding of lead's detrimental effects on the human brain. Lead exposure has been linked to lower student proficiency rates, with researchers equating the impact to lost instruction time. Additionally, lead is known to damage the part of the brain responsible for memory, and its presence has been associated with higher mortality rates in surrounding counties. The switch to unleaded fuel in NASCAR races not only improved educational outcomes but also potentially contributed to enhanced health and well-being for those living near the racetracks.
Overall, NASCAR's decision to switch from leaded to unleaded fuel in 2007 was a significant step forward. It not only aligned with the organization's commitment to high-performance racing but also demonstrated a growing awareness of environmental and health concerns. This change had tangible benefits for the communities located near NASCAR racetracks, highlighting the far-reaching impact of decisions made by organizations with a large public presence.

The switch to unleaded fuel improved educational performance in children living near racetracks
NASCAR cars use a specialized type of fuel known as Sunoco Green E15, which is a 98 octane, unleaded fuel blend. This fuel is specifically engineered for high-performance engines in race cars. The switch to unleaded fuel in NASCAR occurred in 2007, marking a transition from leaded fuel, which was commonly used in professional motor racing until its gradual phase-out began in the 1990s.
The switch to unleaded fuel in NASCAR had a notable impact on the educational performance of children living near racetracks. After the change, it was observed that children in these areas began to perform substantially better in school compared to previous cohorts. Not only did their academic achievements improve, but there were also relative increases in educational performance when compared to students living further away from the racetracks.
The positive impact on educational performance can be attributed to the reduction of lead exposure. Leaded fuel, which was previously used in NASCAR, contained tetraethyllead (TEL), a fuel additive that boosts octane ratings and allows for higher engine compression. However, TEL is an organolead compound that can lead to elevated blood lead levels, which can have detrimental effects on cognitive development and academic performance.
By switching to unleaded fuel, NASCAR not only improved the environmental impact of their races by reducing lead emissions but also inadvertently contributed to the well-being and cognitive development of children living nearby. This improvement in educational performance highlights the far-reaching benefits of reducing lead exposure, providing further support for policies and initiatives that prioritize the use of unleaded fuels and the reduction of lead contamination in communities.
It is worth noting that while the switch to unleaded fuel played a significant role in improving educational outcomes, there may also be other contributing factors at play. For example, socioeconomic factors, access to educational resources, and the quality of schooling can all influence a child's academic performance. Nonetheless, the observed improvements underscore the importance of considering the broader impacts of racing sports on surrounding communities and the potential for positive change through environmentally conscious decisions.

Sunoco has fuelled NASCAR cars for over 20 years
Sunoco has been the official fuel of NASCAR for over 20 years. The specialised NASCAR fuel is Sunoco Green E15, a 98 octane, unleaded fuel blend specifically designed for high-performance engines and race cars. It is also used in junior grassroots stock car racing series, such as the ARCA Menards Series.
Sunoco Green E15 is 85% highly refined racing gasoline. Its use in NASCAR can be traced back to 2007 when the racing organisation switched from leaded to unleaded fuel. This transition was influenced by blood tests of NASCAR teams, which revealed elevated blood lead levels. By making the switch, NASCAR joined other motor racing organisations, which had already begun phasing out leaded fuel in the 1990s. For example, Formula One racing cars have been required to use fuel containing no more than 5mg/L of lead since 1993.
NASCAR's switch to unleaded fuel has had positive impacts beyond the race track. After the change, children who were raised near racetracks began performing better in school than previous cohorts. There were also increases in educational performance relative to students who lived further away from the tracks.
Sunoco's partnership with NASCAR extends beyond just providing fuel for the cars. The company has also been awarding the Sunoco Rookie of the Year for over a decade, recognising notable drivers such as Kyle Larson, Chase Elliot, and the 2024 Daytona 500 winner William Byron. Sunoco's expertise in fuel delivery and environmental and regulatory compliance further solidifies its integral role in NASCAR's success.
