Two-stroke engines, commonly used in tools like disc cutters, chainsaws, and other power equipment, rely on a precise fuel-to-oil mixture for optimal performance. Mixing the correct ratio is essential to ensure the longevity of your engine, prevent damage, and maximize efficiency. In this guide, we’ll walk you through how to properly mix fuel and oil for two-stroke engines and highlight where you can find high-quality products to get the job done right.

Why Is the Fuel-Oil Mix Important?

Two-stroke engines don’t have a separate lubrication system like four-stroke engines. Instead, oil is mixed directly with fuel to lubricate the engine components during operation. An incorrect mix can lead to:

• Too much oil: Excess smoke, fouled spark plugs, and carbon buildup.
• Too little oil: Insufficient lubrication, causing overheating, excessive wear, and potential engine seizure.

Step-by-Step Guide to Mixing Two-Stroke Fuel

1. Check the Manufacturer’s Ratio Recommendation

Most two-stroke engines require a 50:1 or 40:1 fuel-to-oil ratio, but always refer to your tool’s manual for the exact specifications.

2. Use High-Quality Two-Stroke Oil

For the best results, choose a high-quality oil designed specifically for two-stroke engines. HTS Spares offers a range of oils to suit your needs:

• Stihl HP Two-Stroke Engine Oil (1L with measure)
• Stihl HP Super One-Shot 2-Stroke Oil (Semi-Synthetic)

3. Measure the Fuel and Oil Accurately

• Use a clean, approved fuel container.
• For a 50:1 ratio (common for modern tools), mix 100 ml of oil with 5 liters of unleaded petrol.
• For a 40:1 ratio, mix 125 ml of oil with 5 liters of unleaded petrol.

Stihl’s one-shot oils, like the Stihl HP One-Shot 2-Stroke Mineral Oil (Pack of 10), make measuring simple and precise.

4. Mix Thoroughly

• Pour half the petrol into the container.
• Add the measured oil.
• Seal the container and shake well to mix.
• Add the remaining petrol and shake again to ensure even distribution.

5. Label and Store Safely

Always label the container with the mix ratio and the date. Store the mixture in a cool, dry place, and avoid using fuel older than 30 days.

Where to Buy Two-Stroke Oil and Accessories

HTS Spares has everything you need for mixing two-stroke fuel:

• Stihl HP Two-Stroke Engine Oil (1L with measure)
• Stihl HP One-Shot 2-Stroke Mineral Oil
• Stihl HP Super One-Shot 2-Stroke Oil (Semi-Synthetic)
• Golden Film SAE30 Classix Motor Oil

Final Tips

• Always use fresh, high-octane unleaded petrol.
• Clean your mixing container regularly to avoid contamination.
• Never mix fuel directly in the tool’s tank.

Choosing the right antifreeze for your vehicle or machinery is essential to ensure optimal performance and longevity. With various options available, two of the most commonly used types are red and blue antifreeze. But what’s the difference, and which one is right for your needs? Let’s break it down.

What Is Antifreeze?

Antifreeze, also known as coolant, regulates the temperature of your engine by preventing freezing in cold conditions and overheating in hot weather. It also protects your engine components from rust and corrosion. The color of antifreeze often indicates its chemical composition and intended use.

Key Differences Between Red and Blue Antifreeze

Red Antifreeze

• Composition: Red antifreeze is typically made with Organic Acid Technology (OAT).
• Lifespan: Long-lasting, with a lifespan of up to 5 years or 150,000 miles.
• Use: Often used in modern vehicles and machinery with aluminum or metal components.
• Benefits: Provides excellent protection against rust and corrosion, particularly in high-performance systems.

Blue Antifreeze

• Composition: Blue antifreeze is made with Inorganic Additive Technology (IAT).
• Lifespan: Shorter lifespan, typically up to 2 years or 30,000 miles.
• Use: Commonly used in older vehicles or systems requiring traditional antifreeze formulas.
• Benefits: Offers immediate protection and works well in systems designed for frequent maintenance.

Which One Should You Use?

1. Check Your Owner’s Manual
   Always refer to your vehicle or machinery’s owner manual. It specifies the type of antifreeze required based on the engine design and manufacturer’s recommendations.
2. Consider the Age of Your Vehicle or Equipment
   • Older vehicles (pre-2000s) are more likely to require blue antifreeze.
   • Newer models generally perform better with red antifreeze.
3. Compatibility Matters
   Never mix red and blue antifreeze. Mixing them can cause chemical reactions, leading to reduced effectiveness and potential damage to your cooling system.

Additional Tips

• Regular Maintenance: Always flush your cooling system and replace the antifreeze as per the manufacturer’s guidelines.
• Purchase Quality Antifreeze: Using a trusted brand ensures reliable performance and reduces the risk of engine issues.

Final Thoughts

The choice between red and blue antifreeze depends on your vehicle or equipment’s age, design, and the manufacturer’s specifications. Always use the antifreeze that aligns with the requirements of your cooling system to ensure peak performance and protection.

Do not let yourself be caught out this winter with the inconvenience of a flat battery. Chances are you’ve been there before… The lifeless clicks of the ignition because the battery cannot generate enough power to start the engine?

A flat battery is an easily avoidable aggravation if you have the right products.

Battery Charger

The charger operates by converting alternating currents into direct currents and should be purchased based on the type of batteries it is going to be used on. The higher the output or amperage, the longer the charge lasts and the quicker it will charge. A reliable battery charger is an essential for every workshop or garage.

Booster Pack

Alternatively, for on-site situations, a jumper or booster can be used. These packs deliver an instant power signal which is designed to kick-start a battery. These devices have a much higher output than traditional static battery chargers but are not so consistent. Boosters are more useful in an emergency as they can get you up and running instantly, although they are portable, they are not always particularly light weight dependant on the size. Portable jump starters don’t have lithium batteries like the chargers, which makes them more compact so it’s quick and easy to get moving again. Once you have started your engine, it should then be left running for at least 30 minutes. This allows enough time for the alternator to charge the battery.

Now you’ve been warned, there is no excuse to be caught out! If you’d like more information on battery chargers or booster packs, please contact our sister company team at HTS Spares by giving them a call on 01432 373350 or email sales@htsspares.com.
