Sunoco is the official gas brand of NASCAR and has been the exclusive fuel supplier to all three NASCAR national series — the Cup Series, the O’Reilly Auto Parts Series (formerly Xfinity), and the Craftsman Truck Series — since 2004, providing its Sunoco Green E15 racing fuel at every race weekend.
For anyone asking what gas brand sponsors NASCAR or who is NASCAR’s official fuel sponsor, the answer is clear and consistent across all series: Sunoco is the sole nascar fuel sponsor at the series level.
The role of nascar official fuel partner goes far beyond supply. It includes category exclusivity, meaning no competing fuel brand can hold the same position, as well as full integration across NASCAR’s commercial ecosystem. Sunoco branding is visible at all 23 race venues, supported by at-track activation rights and the ability to use NASCAR intellectual property in national campaigns.
As of nascar fuel sponsor 2026 status, Sunoco’s agreement remains active under a multi-year renewal. This long-term continuity reinforces its leadership position and makes sunoco nascar sponsorship one of the most stable commercial partnerships in global motorsport.
| Era | Sponsor | Years | Notes |
|---|---|---|---|
| 1960s–1970s | Various regional fuel brands | Pre-official partnership era | No single exclusive fuel sponsor |
| 1977–1993 | STP | 1977–1993 | Non-fuel association partner |
| 1994–2003 | 76 / Union Oil / Unocal | 1994–2003 | Official fuel before Sunoco |
| 2004–present | Sunoco | 2004–2026+ | Current official fuel partner |
The evolution of the history of nascar fuel sponsors shows how the sport moved from a fragmented supply model to a centralized commercial structure.
The 76 brand, operated by Union Oil and later Unocal, held the official fuel role until 2003. Following ConocoPhillips’ acquisition and strategic repositioning, Sunoco secured the contract starting in 2004.
This transition marked a turning point in nascar fuel sponsor strategy, introducing long-term exclusivity and consistent branding.
No other fuel brand has held NASCAR’s official fuel status in the modern era — Sunoco’s 23-year run is unprecedented in US motorsport supplier history.
Sunoco has been NASCAR’s official fuel supplier since 2004 — a 23-year partnership as of 2026, making it the longest-running fuel supplier in the sport’s modern era.
This duration answers one of the most searched queries: how long has Sunoco been NASCAR fuel sponsor, confirming its unique longevity.
Sunoco’s NASCAR partnership has been renewed through 2026 and beyond under a multi-year agreement. The deal covers all three national series: the Cup Series, the NASCAR O’Reilly Auto Parts Series (formerly Xfinity), and the Craftsman Truck Series.
This confirms that for those searching is Sunoco NASCAR sponsorship confirmed for 2026, the answer is yes — and the agreement extends beyond that horizon.
These benefits highlight why nascar sponsorship opportunities in the energy sector are considered high-value. Sunoco’s continued investment demonstrates measurable ROI for fuel and energy companies.
Sunoco Green E15 is a specially formulated racing fuel with a 98 octane rating and a 15% ethanol blend, developed exclusively for NASCAR’s high-performance engines running at up to 9,000 RPM across all three national series since 2011.
For those asking what gas does NASCAR use or what fuel does NASCAR use in their cars, the answer is Sunoco Green E15.
| Spec | Value |
|---|---|
| Octane rating | 98 RON |
| Ethanol content | 15% (E15) |
| vs standard pump fuel | 87–93 octane, ~10% ethanol |
| Engine RPM | Up to 9,000 RPM |
| CO2 reduction | ~15% lower carbon intensity |
| Introduced | 2011 |
The introduction of E15 marked a key step in nascar green energy sponsorship narratives, combining performance with reduced emissions.
NASCAR continues to explore future fuel innovations, including synthetic fuels and higher ethanol blends, reinforcing its position as a platform for energy transition.
Sunoco holds exclusive category rights as NASCAR’s official fuel supplier, meaning no other fuel or gasoline brand can hold an official NASCAR series-level sponsorship in the fuel category for the duration of the deal.
This answers a common question: why can’t other gas brands sponsor NASCAR at the same level.
However, this does not exclude all participation:
This structure defines how brands approach how to get a gas brand into NASCAR sponsorship, often starting from team-level activation.
Yes — while Sunoco holds series-level exclusivity, individual NASCAR teams can and do partner with other petroleum brands for car livery sponsorship, provided they do not conflict with the series-level official category rights.
Examples include Shell NASCAR sponsorship programs with top teams. These are branding agreements, while Sunoco remains the actual fuel supplier.
| Dimension | Sunoco | Mobil 1 |
|---|---|---|
| Official role | Official Fuel | Official Motor Oil |
| Product | Fuel | Engine oil |
| Function | Energy source | Lubrication |
| Category | Fuel exclusivity | Oil exclusivity |
| Series | All | All |
This comparison answers queries such as what oil brand sponsors NASCAR and clarifies that Mobil 1 operates in a separate category.
Sunoco powers the engine; Mobil 1 protects it.
| Brand | Role | Category | Status 2026 |
|---|---|---|---|
| Sunoco | Official Fuel | Fuel | Active |
| Mobil 1 | Official Motor Oil | Lubricants | Active |
| Monster Energy | Official Energy Drink | Beverage | Active |
| Shell/Pennzoil | Team sponsor | Fuel/Lubricants | Team-level |
This table answers what energy companies sponsor NASCAR 2026, showing both exclusive and non-exclusive roles.
Importantly, energy brands can still access NASCAR through non-restricted categories or team partnerships.
1. Audience Alignment: NASCAR fans are significantly more likely to purchase automotive and fuel-related products.
2. Technical Credibility: Motorsport enables “race-proven” performance claims — a powerful differentiator in the energy sector.
3. At-Venue Reach: With 23 race markets, brands gain direct consumer activation opportunities.

Read MoreIn an era where it is possible to get anywhere with a click, there is a strong temptation to approach teams and properties directly for sponsorship projects.
By doing so, we are convinced that we are shortening the value chain, saving time and money. However, these DYI methods are anything but risk-free and what initially appears to be a competitive advantage soon turns into a problem that is difficult to resolve. That’s why there are agencies. And this is why you should rely on us for your sponsorships.
When first approaching a motorsport sponsorship project, it is difficult to know immediately which stakeholders are correct, what the decision flow is, and what the right timelines are for each process. Motorsport is a very specialized field of action, and fitting effectively into its paths can take a lot of time and therefore money. We, on the other hand, know referents and spheres of action and know who to talk to, when and how. So you are also more effective.
Motorsport is an immense passion, and for our heart colors we would be willing to do anything. But business is a different business, and it is important to make the best possible strategic decisions based on independent research, statistics and reliable data. A motorsport sponsorship agency like RTR has an objective, 360-degree picture of the scenario and can tell you what is really best for you: which racing series, which athlete, which team. This is because we possess a great deal of data and information on ratings, segmentation and attitudes. Because the numbers don’t lie. Never.
Activations are the real heart of motorsport sponsorship. Without them, there remains only a blank sticker on a motorcycle, car or uniform and no contact with the public, no emotional connection, no impact on the bottom line. Then how do you do it? It certainly won’t be the teams or the athletes who will help you leverage sponsorship and enjoy the many marketing rights you have paid for. To bring out the best in a motorsport marketing project, you need an agency that knows how to use sponsorship to engage the fanbase online, to reach out to Shopping Centers, to organize hospitality, to develop B2B and B2C opportunities, and to get “your” athletes in front of millions of potential consumers.
Would you ever go to the dealer who sold you the car and ask if the competitor’s car is better? No, of course. So, how do you expect to get firm measurements of the effectiveness of your sponsorship if you do not rely on someone super partes? At RTR, we have always worked with independent third-party agencies that allow us to know the return on any exposure of your brand on TV and in the media. In addition, we believe in calculating ROI as the ultimate measure of your success-so we can tell you for every penny you spend how much you are making.
We have been involved in motorsport sponsorship and sports marketing for more than 15 years. We are consultants in the sense that our goal is to maximize your investment, but we are also an agency that manages the project from start to finish. We have been doing this since 1995 with passion and professionalism, following three principles that have become cornerstones of our business: independence, verticality and transparency.
I would like to highlight the fact that one of the qualities of RTR is its great ability to approach the sponsorship scenario strategically, together with its passionate attitude, its amazing enthusiasm for solving problems, and its high level of professionalism.

Eurosport is truly delighted with its business relationship with Riccardo Tafà, who has become extremely popular, thanks to his detailed knowledge of the sports marketing sector and his highly diligent attitude to work.
Francois Ribeiro
Commercial Director
Passion and Expertise are the features that I have found in RTR since the very beginning. Serious and reliable professionals but also very helpful, nice and open-mind people, willing to listen and compare different ideas. All the values in which RTR believes make this agency a partner, not just a supplier, a partner with whom we have had the opportunity to achieve significant commercial results in term of success and image.
Luca Pacitto
Head of Communication
We have been working with RTR Sports Marketing for over 10 years. The objectives and the programmes of collaboration continue to be renewed and to grow with mutual satisfaction. I believe RTR is a team of great professionals led by Riccardo Tafà, who I consider a manager of exceptional skills and with a great passion for his work.
Lucio Cecchinello
Team Principal
I have known and worked with Riccardo Tafà since 1995 when we collaborated for the first time on a project for the Williams Formula 1 team. Several clients followed. After leaving Williams to work for Gerhard Berger then owner of the Toro Rosso F1 Team, I turned again to Riccardo to seek his help in finding a tool supplier for the team and Riccardo duly obliged with an introduction to USAG, a partnership with Toro Rosso which endured for five years. I recently started a new role as Group Commercial Director for the renowned Andretti Autosport organisation and I find myself working with Riccardo once again on a number of interesting projects. Why has this relationship with Riccardo endured ? He’s smart, knows the commercial side of sport inside out and back to front and he’s honest and trustworthy. Riccardo Tafà is a “doer” not a “talker”: in over 20 years I have never had a dispute either with him or with a company that he has introduced and each partnership introduced by Riccardo has delivered quantifiable ROI to rights holder and sponsor alike. I can think of no better testimonial of Riccardo’s diligence, knowledge, contact base and hard work than that.
