The warm weather has arrived, and you’re ready to tackle your lawn with your trusty Craftsman mower. But before you fire it up, there’s one crucial question you need to ask: What type of gas should you use? Choosing the wrong fuel can lead to engine problems, poor performance, and even damage. This comprehensive guide will break down everything you need to know about gas for your Craftsman lawn mower, helping you make the best choice for your machine and your wallet.
**In a nutshell, Craftsman lawn mowers are designed to run on regular unleaded gasoline. It’s best to avoid using fuel blends with ethanol, as they can cause issues with your mower’s engine. **
Understanding Fuel Requirements
Understanding the fuel your Craftsman mower needs begins with recognizing the type of engine it uses. Most Craftsman lawn mowers are equipped with small, four-stroke gasoline engines. These engines operate on a mixture of air and fuel, ignited by a spark plug.
Why Regular Unleaded is Best
Regular unleaded gasoline is the standard fuel for most Craftsman lawn mowers. Here’s why:
- Octane Rating: Regular unleaded typically has an octane rating of 87. This rating indicates the fuel’s resistance to knocking or premature detonation, which can damage your engine.
- Additives: Regular unleaded often contains additives that help protect your engine from corrosion, reduce wear and tear, and improve fuel economy.
The Downsides of Ethanol Blends
While ethanol blends are commonly available, they can be problematic for lawn mowers. Here’s what you should know:
- Ethanol Absorption: Ethanol absorbs water from the air, leading to potential water contamination in your fuel tank. Water can cause rust and corrosion in your engine.
- Fuel Degradation: Ethanol can break down over time, forming a gummy residue that clogs fuel lines and carburetor jets, leading to starting problems and poor performance.
- Engine Damage: Ethanol blends can damage some older engines and parts, particularly those made from older materials or with older carburetor technology.
Choosing the Right Fuel: A Quick Guide
- Consult Your Owner’s Manual: The most reliable information will be found in your Craftsman lawn mower’s owner’s manual. It will specify the recommended fuel type, octane rating, and any specific requirements.
- Look for Ethanol-Free Gas: Search for gas stations that sell ethanol-free gasoline (E0).
- If Ethanol is Unavoidable: If ethanol-free gas is unavailable, choose the lowest ethanol blend (E10 or lower).
- Fuel Additives: Consider using fuel stabilizers or additives designed for small engines to help prevent fuel degradation and water absorption.
Taking Care of Your Fuel System
Using the right fuel is only part of the equation. Here are some tips for maintaining your Craftsman lawn mower’s fuel system:
1. Store Fuel Properly
- Fresh Fuel is Best: Try to use up your gasoline within 30 days, especially if it contains ethanol.
- Store in a Cool, Dry Place: Store fuel containers in a well-ventilated area, away from heat and direct sunlight.
- Use a Fuel Stabilizer: Add a fuel stabilizer to your gas tank before storing your mower for extended periods. This helps prevent the formation of fuel deposits and ensures a smooth start the next time you need it.
2. Clean Your Fuel System
- Regularly Clean the Carburetor: Over time, dirt and debris can accumulate in your carburetor, leading to performance issues.
- Replace Fuel Filters: Fuel filters are designed to trap impurities in your fuel. Replace them according to the manufacturer’s recommendations.
Troubleshooting Common Fuel-Related Problems
If you’re experiencing problems with your Craftsman lawn mower, the issue may be related to fuel. Here are some common symptoms and solutions:
- Difficult Starting: If your mower has trouble starting, the problem might be due to old, stale gas, a clogged fuel filter, or a dirty carburetor.
- Stalling or Hesitation: If your engine stalls or hesitates, you could have a fuel delivery problem. Check for a clogged fuel filter or carburetor, and consider adding a fuel stabilizer.
- Poor Engine Performance: A loss of power or sluggish operation can also indicate fuel issues. Start with checking the fuel filter and carburetor.
Conclusion
Choosing the right type of gas for your Craftsman lawn mower is critical for its performance, longevity, and your peace of mind. Sticking to regular unleaded gasoline, ideally with no ethanol content, will help you avoid potential fuel-related problems. Regular maintenance and proper fuel storage will keep your mower running smoothly for years to come.
Frequently Asked Questions
Q1: What kind of gas should I use in my Craftsman lawn mower?
The type of gas you should use for your Craftsman lawn mower is regular unleaded gasoline. This is the most common type of gasoline available at gas stations, and it’s the best choice for your mower because it’s designed to provide the optimal balance of power and fuel efficiency. Avoid using premium gasoline, as it’s not formulated for small engines and can actually harm your mower.
Q2: Can I use ethanol-blended gasoline in my Craftsman lawn mower?
While some mowers are designed to handle ethanol-blended gasoline, it’s best to avoid using it in your Craftsman lawn mower. Ethanol can attract moisture, which can lead to corrosion and damage to the internal parts of your mower’s engine. If you’re unsure, check your owner’s manual for specific recommendations on fuel type.
Q3: What is the best octane rating for my Craftsman lawn mower?
The recommended octane rating for your Craftsman lawn mower will be listed in your owner’s manual. Generally, 87 octane is sufficient for most small engines. Using a higher octane rating won’t provide any performance benefits and could actually waste money.
Q4: Should I use fresh gasoline in my Craftsman lawn mower?
It’s best to use fresh gasoline in your Craftsman lawn mower. Gasoline can deteriorate over time, especially in hot temperatures. Old gasoline can gum up the engine and cause problems. It’s a good rule of thumb to use gasoline that’s no older than 30 days.
Q5: How do I store gasoline for my Craftsman lawn mower?
If you need to store gasoline for your Craftsman lawn mower, it’s crucial to do so properly. Store gasoline in a sealed, airtight container in a cool, dry place away from direct sunlight and heat. Always label the container with the date it was filled.
Q6: Can I use diesel fuel in my Craftsman lawn mower?
