Higher ethanol gasoline blends harm the environment, causing air pollution and reducing fuel efficiency. Many are switching to ethanol-free recreational fuel.
You might be wondering, what is recreational fuel?
Many consumers prefer non-ethanol recreational fuel for boats, motorcycles, ATVs, and classic cars due to its enhanced performance.
This article explores rec fuel, its types, applications, pros and cons, and guidance on selecting the best fuel for your equipment.
What is Recreational Fuel?
Recreational fuel (Rec Fuel) is ethanol-free gasoline for ethanol-sensitive engines—ideal for marine craft, classic cars, outboards, ATVs, jet skis, snowblowers, chainsaws, lawnmowers, generators and other small or seasonal equipment.
Because it contains no ethanol, rec fuel prevents moisture absorption and corrosion common in regular blends, making it ideal for extended periods of time.
REC-90, the most common grade, has a 90 octane rating, providing stable, efficient performance for small engines and marine use.
How Recreational Fuel Differs from Regular Gasoline
REC-90 recreational fuel contains zero ethanol, while regular gasoline (E10) contains up to 10%, making REC-90 the safer option for ethanol sensitive engines.
The key difference between recreational fuel and regular gasoline lies in ethanol content:
| Feature | Recreational Fuel | Regular Gasoline |
|---|---|---|
| Ethanol Content | 0% | Up to 10% (E-10) |
| Octane Rating | 90 (REC-90) | 87–93 |
| Stability | Higher (longer shelf life) | Lower (due to ethanol as it attracts moisture) |
| Typical Use | Boats, ATVs, small engines, classic cars, seasonal equipment | Daily driving vehicles, cars, trucks, etc. |
| Emissions | Lower evaporative emissions | Higher due to ethanol oxidation |
Unlike regular gasoline, REC-90 contains no ethanol, reducing moisture absorption and fuel system corrosion. This makes it ideal for engines stored long-term or used intermittently.
Ethanol in regular gasoline can cause rubber and plastic fuel parts to degrade, while recreational fuel offers longer shelf life and more consistent combustion.
Although it costs about $0.50–$1.00 more per gallon, REC-90 delivers better engine longevity and performance for equipment not used daily.
Types of Recreational Fuel
Here are some common types of recreational fuel:
1. Ethanol-Free Gasoline
Ethanol-free gas is ideal for small engines in recreational vehicles like ATVs and motorcycles as it prevents moisture attraction, corrosion, and engine damage, ensuring a clean fuel line.
2. High-Octane Racing Fuels
High-octane racing fuels (aka rec fuel), typically 110–118+ octane, let high-performance engines run at higher compression and temperatures without detonation.
3. LPG or Propane
Avgas is a specialized form of recreational fuel used in piston-engine aircraft, available in grades like 100LL (low-lead).
Formulated for aviation engines, it ensures high reliability and consistent performance at different altitudes and temperatures while resisting vapor lock.
Additives in avgas prevent icing and corrosion, essential for aircraft safety and engine longevity.
Outside of aviation, propane is also a common choice for commercial and fleet vehicles. See how it compares to natural gas for fleet use if you’re evaluating fuel options beyond gasoline.
Why Some Engines Need Ethanol-Free Fuel
Ethanol absorbs water, which can cause fuel separation, carburetor corrosion and hard starts in small engines that sit unused for weeks or months.
Many small and recreational engines lack closed fuel systems or ethanol-resistant components.
Using non-ethanol gas prevents:
- Water buildup in the fuel system
- Carburetor corrosion and clogged jets
- Degraded fuel during seasonal storage
Example: Marine engines stored for months often fail when fueled with ethanol gas but run smoothly when using REC-90 fuel.
Benefits of Using Recreational Fuel
Ethanol-free fuel offers many advantages over regular gasoline. Here are some prominent benefits of using recreational fuel:
- REC-90 prevents moisture absorption and fuel system corrosion common in ethanol-blended fuels.
- Ethanol-free gasoline reduces maintenance costs by lowering the risk of carburetor clogging and engine corrosion.
- Recreational fuel has a longer shelf life than ethanol blends because it does not attract moisture.
- REC-90 is the preferred fuel for boat owners because it prevents deposits and phase separation in marine engines.
When to Use Recreational Fuel
REC-90 recreational fuel is best suited for seasonal vehicles, marine engines and small equipment that sit unused for weeks or months at a time.
Use it when:
- Operating boats, jet skis, ATVs, or lawn equipment
- Running classic cars or motorcycles that predate ethanol-compatible systems
- Storing fuel for extended periods (thanks to better stability)
Using the correct fuel reduces corrosion, starting issues, and costly maintenance especially in humid environments where ethanol can attract water.
Cons of Using Recreational Fuel
REC-90 also has some disadvantages:
- Rec 90 fuel is more expensive because it requires additional refining to remove ethanol.
- It is not readily available to customers.
- Rec fuel may have a lower energy content than ethanol-blended gasoline.
How to Find Recreational Fuel and Choose the Right Rec Fuel for Your Equipment
Understanding octane is vital when selecting recreational fuel like REC-90. However, octane alone doesn’t guarantee the best choice; other factors are crucial.
Verify engine compatibility before choosing recreational fuel. It’s essential to opt for ethanol-free options to prevent issues associated with ethanol blends.
Check local regulations for any specific ethanol-free fuel requirements. Consider the intended use of recreational gasoline to ensure proper application.
Ensure adequate supply of recreational fuel to avoid shortages. To find recreational fuel nearby, visit gas stations that offer ethanol-free options. Marinas in harbor or lakeside areas also provide access to pure gasoline.
In the United States, fuel stations offer three grades of fuel: regular, midgrade, and premium. Recreational fuel falls into the midgrade category. REC-90 gasoline is almost always more expensive per gallon than regular gasoline because it does not contain inexpensive oxygenates.
The cost of REC fuel varies from state to state and city to city.
On average, the price of midgrade fuel (octane rating 89-90) is $3.970, which is slightly higher than the average price of regular fuel, which is $3.519.
Legal and Safety
It’s crucial to adhere to regulations for the safe storage and handling of recreational fuel to prevent accidents and environmental harm.
Following fuel safety precautions reduces risks and costs.
Store recreational fuel in a cool, dark place, filling the fuel tank completely to limit air exposure, and consider adding a stabilizer to maintain fuel quality.
Many people question the use of REC-90 fuel in cars, asking if recreational fuel or ethanol-free gas can be used.
Recreational fuel is mainly designed for marine equipment and small engines, but it can be used in standard car engines without causing harm. Some drivers prefer non-ethanol fuel options for better gas mileage and performance. However, it’s advisable to avoid its use in regular vehicles as it may not be suitable for heavy engines long-term.
