Quick Answer
Investing in premium fuel for generators is generally not worth the extra cost, as it offers minimal benefits for most users and may not justify the increased expense.
Fuel Types and Quality
When choosing a fuel for your generator, it’s essential to understand the differences between regular, mid-grade, and premium gasoline. Regular gasoline is the most common type, suitable for most generators, while mid-grade and premium gasoline contain higher octane levels. However, unless your generator specifically requires premium fuel, it’s unlikely you’ll see significant performance improvements.
Storage and Stabilization
Long-term generator storage requires careful consideration of fuel quality and stabilization. Gasoline breaks down over time, leading to varnish and gum formation, which can clog engine components. Stabilizers can help slow this process, but their effectiveness varies depending on storage conditions and fuel type. If storing your generator for extended periods (e.g., 30 days or longer), consider using a fuel stabilizer and filling your tank about 1/4 full to minimize exposure to air.
Generator-Specific Requirements
Some generators, particularly those used for commercial or high-performance applications, may require premium fuel to maintain optimal performance. Check your generator’s manual or manufacturer’s website to determine the recommended fuel type. If you’re unsure, it’s best to err on the side of caution and stick with regular gasoline, which is generally less expensive and widely available.
