About 2 Stroke Fuel Mix Calculator
2 Stroke Fuel Mix Calculator tells you exactly how much 2-cycle oil to add to your gasoline for the perfect mixture — every time you fill up.
Chainsaws, string trimmers, leaf blowers, lawn mowers, outboard motors, dirt bikes and other 2-stroke engines need gas premixed with oil at a specific ratio. Too little oil and the engine can seize; too much and it fouls and smokes. This app removes the guesswork.
[ HOW IT WORKS ]
● Enter Your Fuel
Type the amount of gasoline you are mixing and choose the unit — liters, US gallons, or UK gallons.
● Pick a Ratio
Tap a common preset — 16:1, 24:1, 25:1, 32:1, 40:1, or 50:1 — or enter your own custom ratio to match your equipment manual.
● Read the Oil Amount
The exact oil quantity is shown instantly in both milliliters and fluid ounces, along with the total mixture volume.
● Copy & Go
Copy the result with one tap so you can take it to the pump or the workbench.
[ COMMON RATIOS ]
- 50:1 — many modern chainsaws and trimmers
- 40:1 — common for older two-stroke tools
- 32:1 and 25:1 — vintage equipment and some outboards
- Always follow the ratio in your equipment's manual
[ GREAT FOR ]
- Chainsaw and trimmer owners
- Lawn care and landscaping work
- Outboard boat motors and jet skis
- Dirt bikes, mopeds and scooters
- Anyone who mixes two-stroke fuel by hand
[ ACCURACY NOTE ]
Results are calculated from the fuel amount and ratio you enter. Always confirm the correct ratio in your engine manufacturer's manual before mixing. This app is a convenience tool and not a substitute for official guidance.
Enter your fuel, pick your ratio, and mix with confidence.
