# Oil and Gas Ratio Calculator

## Guide to Use Oil and Gas Ratio Calculator

• Enter Gallons of Gas: Input the amount of gasoline (in US gallons) you plan to use.
• Enter Gas-to-Oil Ratio: Input the required gas-to-oil ratio for your engine (e.g., 50:1).
• Choose Your Calculation System: Click on “Calculate US” for results in US ounces or “Calculate Metric” for results in milliliters (ml).
• Reset: Clears all inputs and results for a new calculation.

## Understanding the Inputs

• Gallons of Gas: The volume of gasoline you have or plan to mix with oil.
• Gas-to-Oil Ratio: This is the ratio of gasoline to oil recommended by your engine’s manufacturer. Common ratios include 50:1, 40:1, and 32:1.

## How the Calculation Works

The calculator uses the input ratio and volume of gasoline to determine the exact amount of oil needed to achieve the correct mixture. For a 50:1 ratio, for example, you would need 1 part oil for every 50 parts gasoline.

The calculator converts this ratio into a measurable quantity of oil based on the volume of gasoline entered, providing results in either US ounces or milliliters.

## Formula

For the US system (where gasoline is measured in gallons and oil in ounces)

• 128 ounces is the number of ounces in one US gallon, as there are 128 US fluid ounces in gas
• Gallons of Gas is the amount of gasoline you plan to use, measured in gallons.
• Gas-to-Oil Ratio is the recommended mixture ratio (e.g., 50:1), which indicates how much par gasoline is mixed with one part of oil.

For the Metric system (where gasoline is measured in liters and oil in milliliters):

• 3.78541 liters is the number of liters in one US gallon, used to convert gallons to liters
• 1000 milliliters is the number of milliliters in one liter, used to convert liters of oil required to milliliters.
• Gallons of Gas is converted to liters before calculating the oil required in milliliters.
• Gas-to-Oil Ratio remains the same, dictating the proportion of gasoline to oil.

## Who Can Use This Calculator

This tool is invaluable for anyone using two-stroke engines, including:

• Gardeners and landscapers
• Motorcyclists and boaters
• Hobbyists with remote-controlled vehicles
• Professionals in the construction and agricultural sectors

• Snowmobiles
• Outboard motors

## FAQs

### Why is the correct oil-to-gas ratio important?

The right mixture ensures adequate lubrication for the engine’s moving parts, preventing overheating and wear.

### Can I use any type of oil with gasoline?

No, you should use two-stroke engine oil specifically designed for mixing with gasoline.

### What happens if I use too much oil in the mixture?

Excess oil can lead to spark plug fouling, exhaust port blocking, and decreased engine performance.

## Conclusion

The Oil and Gas Ratio Calculator is a simple yet powerful tool for anyone using two-stroke engines. By ensuring you have the correct oil and gasoline mixture, you’re not only extending the life of your engine but also promoting better performance and reliability.

This tool is a must-have for maintaining your equipment’s efficiency and preventing engine damage.
