Why Is the Husqvarna weed eater fuel mix Important? 

Before we understand the ratio calculation, you should know why you need to follow the ratio.

If you have the Husqvarna weed eater, you may know Husqvarna is a small machine with a small engine rather than a big one. 

Since the machine is not big, there’s only one tank for fuel and oil.

While the big machine, like a mower, comes with two different tanks; one fuels the engine, and the other lubricates it.

So here in a small engine, one tank will do both jobs. 

When the small engine works, the piston travels ups and down between the two metal surfaces.

If you don’t provide a sufficient amount of oil with the fuel, the piston will be scored and won’t work. 

You can see the image below; on one side, there’s a normal piston, and on the other side a scored piston.

How to Calculate Fuel Mix Ratio?

If you’ve decided what ratio you want, it’s time to move toward the next point, which is how to calculate the fuel mix ratio. 

• First, calculate how much fuel you have in milliliters. It’s not difficult; just understand 1 liter is equal to 1000 milliliters. So if you have 5-liter means, it’s 5000 milliliters. 
• Turn on the calculator and divide the ratio; it can be 32, 40, 50, or even 100 by the amount of fuel you have in milliliters. The answer will be the quantity of oil you need to add to the fuel. Let’s understand it with examples below.

Example One of 50:1 Ratio: 

Here we’re taking 50 from the ratio of 50:1, for example. So divide 50 by 5000 milliliters; the answer should be 100 milliliters.

You need 5000 milliliters of fuel and 100 milliliters of oil. 

Example Two of 40:1 Ratio: 

In the same way, you’ll do the calculation of the 40:1 ratio. Suppose you have 5 liters which are equal to 5000 milliliters.

Divide 40 by 5000 milliliters; you’ll get the answer 125 milliliters. You need 5000 milliliters of fuel and 125 milliliters of oil.
