88 gas, often marketed as Unleaded 88, is a specific type of gasoline blend known as E15. It is designed to be a more efficient and environmentally friendly fuel option.
Understanding Unleaded 88 (E15)
Unleaded 88, or E15, is a fuel blend consisting of 15% ethanol and 85% gasoline. This composition makes it distinct from E10, which is the most common fuel sold in the United States and contains 10% ethanol. The "88" in its name typically refers to its octane rating, which is generally 88, higher than the 87 octane found in standard E10 gasoline.
Key Characteristics of E15
- Ethanol Content: E15 contains 5% more ethanol than the widely used E10 fuel. Ethanol is a renewable fuel source often derived from corn or other plant materials.
- Octane Rating: With a typical octane rating of 88, E15 offers a slightly higher octane level compared to E10 (87 octane). Higher octane can lead to improved engine performance and efficiency in compatible vehicles.
- Availability: Increasingly available at gas stations across the U.S., E15 is often clearly labeled as "Unleaded 88" or "E15" to help consumers identify it.
E15 vs. E10: A Quick Comparison
To better understand 88 gas, it's helpful to compare it with E10, the most common gasoline blend.
| Feature | Unleaded 88 (E15) | Standard Gasoline (E10) |
|---|---|---|
| Ethanol Blend | 15% ethanol, 85% gasoline | 10% ethanol, 90% gasoline |
| Octane Rating | Typically 88 octane | Typically 87 octane |
| Common Use | Approved for use in most vehicles 2001 and newer | Most common fuel in the U.S., widely compatible |
| Benefits | Often burns cleaner, potentially more affordable | Broad compatibility, standard for many older vehicles |
