50:1 Fuel Mixture Calculator
This calculator helps you determine the correct amount of oil to mix with gasoline to achieve a 50:1 fuel ratio. This ratio is commonly used for small engines such as those found in chainsaws, trimmers, and some motorcycles. Maintaining the correct fuel-oil mixture is crucial for the longevity and performance of these engines. Too little oil can lead to engine seizure due to overheating and lack of lubrication, while too much oil can cause excessive smoke, fouled spark plugs, and poor engine performance. Always refer to your equipment's manual for specific fuel mixture recommendations.
Calculate
function calculateFuelMixture() {
var gasolineAmount = parseFloat(document.getElementById("gasolineAmount").value);
var oilType = document.getElementById("oilType").value;
var resultDiv = document.getElementById("result");
resultDiv.innerHTML = ""; // Clear previous results
if (isNaN(gasolineAmount) || gasolineAmount <= 0) {
resultDiv.innerHTML = "Please enter a valid positive amount of gasoline.";
return;
}
var oilAmount = 0;
var ratioParts = oilType.split(':');
var gasolinePart = parseInt(ratioParts[0]);
var oilPart = parseInt(ratioParts[1]);
// Formula: Oil Amount = (Gasoline Amount / Gasoline Part) * Oil Part
oilAmount = (gasolineAmount / gasolinePart) * oilPart;
// Convert liters to milliliters for a more practical measurement for oil
var oilAmountMl = oilAmount * 1000;
resultDiv.innerHTML =
"For " + gasolineAmount + " Liters of gasoline:" +
"You need
" + oilAmount.toFixed(3) + " Liters of 2-stroke oil." +
"(Approximately
" + oilAmountMl.toFixed(0) + " ml of 2-stroke oil)";
