If you’ve ever stood at the pump wondering whether to go with regular, mid-grade, premium, or ethanol-free gasoline—and which handle to grab—you’re not alone. The answer to “what type of gas is best?” depends on your vehicle, your needs, and even your fuel system. And at Rockingham Petroleum, we want to make it simple.
That’s why we offer a full range of fuel options—and we’re here to help you know exactly what you’re putting in your tank.
Understanding Gas Types
⛽ Regular Unleaded (E10 – Contains Ethanol)
Octane: 87
Best for: Most daily drivers
Handle Color: Black
This is the most common fuel for today’s vehicles and contains up to 10% ethanol. It’s usually the most budget-friendly option and works well in most modern engines.
⛽ Non-Ethanol Gasoline
Octanes Available: 87 (Regular), 89 (Mid-grade), and 93 (Premium)
Best for: Small engines, boats, classic cars, motorcycles, equipment, and long-term storage
Handle Color: White
Non-ethanol fuel burns cleaner in certain engines, stores longer, and reduces the risk of damage to equipment not designed for ethanol-blended fuel.
🛢 Diesel
Handle Color: Green
We also offer premium-treated diesel, perfect for farm, fleet, and personal diesel-powered vehicles. Our fuel is treated with a pour point additive to prevent gelling in cold weather—no additional winter treatment needed.

|---|---|---|
| Regular E10 (87) | Black | Yes (10%) |
