What are The Differences: 40 to 1 VS 50 to 1 Oil Mix?

40 to 1 VS 50 to 1 Oil Mix

You may not know well about power engines. Power engines are identified based on the cycle, such as two cycles or four-cycle engines. When you visit the market to purchase power equipment, you may see several power equipment verities. But the main question that the store owner will ask you is that what type of power equipment you need means 2-Cycle or 4-cycle engine.

You may get confused and start thinking about which one is a better choice for you. You can analyze by name that the 4-cyle engine is powerful than the 2-cycle engine, but it is not as you are thinking. Today, we will guide you with complete information about 2-cycle and 4-cycle power engines based on oil mixing ratios such as 40 to 1 and 50 to 1. We will also compare 40 to 1 and 50 1 oil mix.

What is a 2-Cycle engine?

What is a 2-Cycle engine

If you are looking for a high-power engine that should be compatible with different DIY projects and big projects, then a 2-cycle engine is your best choice. It is a lighter choice with a robust design and features. You will find it more powerful, fast running, and a better choice than 4-cycle engines of equal displacement. They are flexible to use in any of the position even in the upside-down position it performs well.

There is plenty of advantage that makes it a better choice than a 4-cycle engine because it requires minor wear and tear and maintenance. You do not need to lubricate a 2-cycle engine’s board, such as motor oil in a crank case. No crank case includes a 2-cycle engine; such engines require lubrication to be added to the fuel. Experts refer to this fuel as 2-Stroke oil or 2-cycle oil formulated on the base mixing of oil and gasoline in a different prescribed ratio.

In 1990 2-cycle engines were launched with a ratio of 32:1, but now the new brands supplied with 40:1 oil mix ratio, and now modern 2-Cycle engines come in 50 to 1 ratio.

What is a 4-cyle engine?

What is a 4-cyle engine

Four cycle engine has a separate compartment for an oil called crankcase. It needs proper maintenance and requires regular interval maintenance. These engines are clean running, but they are bulky or heavy and hard to transport. The ratio mix of fuel uses as 40 to 1, or 50 to 1 ratio it is a poor choice compared to 2-cycle.

EPA standard for oil mixing ratio

EPA set the standard for oil mixing ratio to make powerful equipment’s, so after setting this standard, the poor ratio oil mixes such as 16:1 and 32: 1 obsolete from the market. The lowest standard of oil mixing is a 40 to 1 ratio in the market to ensure better performance.

The maximum amount of oil in the 40:1 ratio standard means 3.2 ounces of oil per gallon of gasoline. Such a ratio is standard in 4-Cycle engines.

While 50:1 ratio means 50 parts of gasoline to one amount of a 2-Cycle oil, about 2.6 ounces of oil for one gallon of gasoline. 50: 1 ratio is the standard ratio of oil mix use for 2-cycle engines used for working in home depot.

 As the demand for the ratio of 32:1 has increased to 50:1, this also creates the need for the ideal oil base that can achieve the need for lubrication by the equipment, but it uses less fuel than lower ratio engines.  It also shows that as they use a lesser amount of fuel, it also exhausts fewer air emissions that make it environmentally friendly. There synthetic or blended synthetic oil is used.

There is not much difference between 50 to 1 and 40 to 1 oil mix, before setting the standard by EPA market already adopted 50:1 ratio. Most of the engines are manufactured and uses a 50: 1 ratio oil mix, but still, 40 to 1 ratio oil mixes are available in the market. 

How to make a 50 to 1 oil mix ratio?

It is not a challenging task; you need to use the careful measurement of fuel while mixing. Here is the simple way to make 50 to 1 oil mix.

  • First of all, purchase the required amount of gasoline and oil from the local market store.
  • After that, choose an airy place to work and adequately set all of your equipment.
  • To achieve a 50 to 1 oil mix ratio, you will need to mix 2.6 ounces of oil in one gallon of gasoline.
  • Suppose you have two gallons of gasoline, then first measure 2.6 ounces of oil and mix them in 2 gallons of gasoline. It has been done.

How to make 40 to 1 oil mix?

There is no much difference except the amount of fuel you will use to prepare a 40 to 1 fuel mix. In 40 to 1 fuel mix means that you will need 3.2 ounces of fuel to mix in one gallon of gasoline.

  • Purchase 2 gallons of gasoline and 6.4 ounces of oil to prepare 40 to 1 oil mix
  • Now measure and add 6.4 ounces of fuel in 2 gallons of gasoline and mix them well.
  • It has been done; you have prepared 40 to 1 oil mix to use in the power engine.

There is no need to worry about using 40 to 1 instead of 50 to 1 oil mix because it is also according to the EPA standard, and there is no much difference between their ratios. You may also not found much difference in performance, but 50 to 1 is a better choice according to performance and environment-friendly nature. But 50 to 1 oil mix is a little bit costly than 40 to 1.

Final Thoughts

EPA standard approves maximum oil ratio 40 to 1 or less than that. The modern market is already using a 50 to 1 ratio that is better than 50 to 1, but 40 to 1 is still working, and some people use that ratio for the oil mix. 50 to 1 is better to choose than 40 to 1, but there is no much difference in performance because there is a minor difference in ratio. You can choose any according to your budget.
