Two-stroke engines require leaded fuel because the lead acts as a lubricant for the piston rings. Without lead, the piston rings can wear out quickly, causing the engine to lose power and efficiency.
Leaded fuel is no longer available at most gas stations, so you will need to find a specialty fuel supplier to purchase it. You can also add lead substitute to unleaded fuel to make it safe to use in a two-stroke engine.
Here are some tips for using leaded fuel in an old car:
* Use the lowest octane fuel that your engine requires.
* Add lead substitute to the fuel at the recommended dosage.
* Avoid using fuel that contains ethanol, as it can damage the engine.
* Have your engine tuned up regularly to keep it running at its best.
