- The oil required for this mixture comes designed to meet the needs of an air-cooled two-cycle engine. This single piston engine runs at high speeds over 8,000 RPMs, which generates enormous heat and friction. If the engine oil doesn't lubricate the piston and crankcase, it will only take a few minutes to damage them. Homelite manufactures its own brand of two-cycle engine oil, though this isn't a requirement, only a strong suggestion. Homelite tested all of its engines using this oil at the given mixture, so it can verify performance levels. However, any high-quality air-cooled inboard two-cycle engine oil will work well.
- Regular unleaded gasoline is standard in all Homelite trimmers, including the Trimlite model. Gasoline should have a rating of at least 87 octane or higher and shouldn't be mixed with special blends, like ethanol or alcohol, which will destroy plastic parts inside the carburetor. Use the highest rated gasoline in your area for the best engine results. These engines generate enormous friction and the higher the quality the fuel, the longer the engine will last.
- The ratio given by the Homelite Company is 50-to-1 gas to oil. This requires a 2.6 fl. oz bottle of two-cycle air-cooled engine oil for each gallon of gasoline. If you don't use this mixture, the pressure will cause your piston to seize. Richening the mixture---adding oil---can have a detrimental effect on the sensitive plastic inside the engine.
- Homelite recommends pre-mixing the fuel before putting it into the Trimlite. Pour the proper oil into a clean fuel container and fill the rest with the proper gasoline. After filling, shake the canister vigorously to ensure an even blend. Homelite also suggests shaking the canister before every refill. Throw away any mixed gas older than 30 days, since the oil will start separating from the gas and will stick to the carburetor and fuel lines.
