What Is 2-Stroke Oil?

carpenter using chainsaw

A 2-stroke oil, which some also refer to as 2T, 2-cycle, or two-cycle, is a type of motor grease. People use it for crankcase compression of two-stroke engines, typically small gasoline-powered ones.

A four-stroke has a closed crankcase except for the ventilation system. On the other hand, a two-stroke leverages the crankcase for the induction tract, allowing the grease to mix with the gasoline before it lubricates the entire engine. We call it petrol or premix. Ultimately, the grease burns along with the fuel.

Synthetic grease, castor, semi-synthetic, and petroleum are some choices to mix with gasoline. The fuel-to-oil ratio ranges from 16:1 to 100:1.

You should not use a 4-stroke oil in a 2-stroke engine or vice versa because it will disrupt combustion, causing degradation and smoke formation. It would not be healthy for your vehicle and may cause it to malfunction. 

Is All 2 Stroke Oil The Same?

If you are looking for a 2-stroke oil for your unit, you may get caught in the middle of several brands or manufacturers. So it is natural to ask yourself if all these are the same. Do you think one brand is superior, or are all essentially the same?

The truth here is that all of them are the same. Performance-wise, these will provide the same protection and lubrication for your two-stroke. Although all are functionally the same, there are three kinds – full synthetic, semi-synthetic, and mineral.

The purpose of these is to apply lubrication to the crankcase compression. You do not have to worry about anything because you can use any of these three interchangeably. For example, you can mix a semi-synthetic with mineral grease and load it into your engine without issues.

When To Use 2-Cycle Oil Mix

A ratio represents the proportions of gasoline and grease in the mixture. In the equipment operator’s manual or the engine label, you can find the required gas oil ratio for the 2-cycle oil mix for your engine. If you cannot find either but are aware of the equipment’s age, most portable devices built before 2003 need a 32:1 ratio, whereas those manufactured after 2002 utilize a 40:1 or 50:1 ratio. The majority of outboard motors need a 50:1 ratio.

Follow this ratio for all 2-cycle grease mixtures to get optimal results. Here are a few warnings to always keep in mind:

  • Avoid automobile motor grease containing non-combustible additives because they will damage the engine. Use only a 2-cycle engine grease for this application.
  • Avoid using gasoline containing more than 10% ethanol. It attracts moisture, causing gasoline to break down. Eventually, it will lead to permanent damage. 
  • Avoid approximating or guessing your mixtures. Always use the proper measuring tools. An engine requires the exact mix of lubrication and fuel to run without issues. 
  • Using a clean container, combine your grease and gas before pouring it into the engine. Never combine these directly because it will cause permanent damage. Make sure the container is clean and free from foreign substances or particles. Pat dry with a paper towel when rinsing the container with water. 
  • Check the fuel level to ensure the mixture has not deteriorated if your engine has been idle for more than a month, such as when removing it from winter storage.

These are some of the most basic knowledge you should know. You will learn the rest through experience as you maintain your vehicle.

Can You Mix Synthetic With Regular Oil?

You may have several questions about synthetic and regular greases for your vehicle. Can you mix these two? Yes, you can do it occasionally as it should not damage your engine. Its viscosity or weight should be within the owner manual’s recommendation.

However, we do not recommend mixing these in regularly and should not become a regular practice. You might be wondering why is that the case? Let us take a better look at motor grease and its design.

It goes around your motor, lubricating the moving parts. This process reduces friction and serves as a prevention of overheating components. The same can sweep up contaminants and deposits, filtering them out. This process should keep your engine running clean and smooth, effectively extending its lifespan.

As discussed in one of the previous sections, there are three varieties of motor grease. These involved thorough scientific research. Mixing them up and hoping for better efficiency and performance is irrelevant. It is only a waste of your money if that is an issue. Here is a good illustration for your reference:

  1. Mixing regular and synthetic grease will not improve the efficiency and performance of regular grease. 
  2. Mixing synthetic and regular grease may dilute the benefits of synthetic, which is more expensive.

In reality, synthetic costs more than conventional or regular. Mixing these is a waste of money, and you are only diluting the advantages of synthetic.

However, mixing these two for a short-term fix, such as when the only available option is to mix them, is okay. It is not the best approach and should not become a habit.

Since we are on the topic of mixing grease, what about combining the same variety across different brands? It should not cause any issues because, chemically, they are the same. 

What about switching between varieties of motor oils? Can customers do that without encountering issues? Yes, you can change to a different variety anytime you wish. These are some questions to keep in mind before switching types:

  • Do you drive in a traffic location?
  • Do you drive in extreme temperatures?
  • Do you drive at high speed for an extended period?
  • Do you take multiple trips per day, totaling a length of 5 to 10 miles?
  • Do you haul heavy loads?
  • Do you drive in harsh, muddy conditions?
  • Do you drive in mountainous terrain?

Here is a high-level overview of how to change oil:

  • Carefully remove and safely dispose of the used grease
  • Replace it with a new one, ensuring it meets manufacturer specifications, such as volume, weight, and type
  • Inspect the filter and replace it with a clean one
  • Refill other fluids, such as washer, transfer case, power steering, and transmission fluid
  • Clean interior and exterior of the vehicle

Best 2-Stroke Oil

At this point, you will have enough knowledge about 2-stroke oil, including its uses. For the engine to function correctly, you must fill it with the correct two-stroke engine oil.

There are thousands of available choices in the market. We curated a list of the top engine greases to buy. The following were picked using three main factors:

50:1 engine oil

Type of Oil

The three types are synthetic, semi-synthetic, and mineral. Synthetic oils are the best type available, but they cost the most. It is not the most common choice for gardening equipment and old bicycles. The mineral type is a more common choice for this equipment.

Emission

All oil types will produce smoke on combustion. The difference lies in the amount of smoke it dispurses.

Some types excrete more smoke than others, while some produce less. Certain brands advertise their product to be low smoke emissions. 

Cleaning and Lubrication

2-stroke engine oils are capable of lubricating and cleaning your engine. Certain brands would have superior clean properties over other brands, allowing for more effective performance. We recommended choosing one with the best value for money.

32/1, 40/1, & 50 to 1 Fuel Mix Chart In Gallons & Litres

All these ratios might get confusing over time. So we put up a chart for your easy reference. Do make sure you are using the right 2-stroke/2-cycle oil-to-gas ratio. You will not have to use a calculator to do the computations. Other ratios are available, such as 30:1, 25:1, and 20:1, but those are less common. Take a look at the most common 50 to 1 fuel mix chart in gallons below to create your 2-cycle oil.

Mixing Ratio (Gas:Oil)Gasoline (vol.)2-Cycle Oil (vol.)
32:11 US gal. (128 oz)4 oz.
32:11 liter31.25 ml
40:11 US gal. (128 oz)3.2 oz. 
40:11 liter25 ml
50:11 US gal. (128 oz)2.6 oz.
50:11 liter20 ml

For a 32:1 mixture, you need 128 ounces of gasoline and 4 ounces of 2-cycle oil or one-liter gasoline and 31.25 milliliters of oil. 

For a 40:1 mixture, you need 128 ounces of gasoline and 3.2 ounces of 2-cycle oil or one-liter gasoline and 25 milliliters of oil.

For a 50:1 mixture, you need 128 ounces of gasoline and 2.6 ounces of 2-cycle oil or one-liter gasoline and 20 milliliters of oil.

2 Stroke Oil vs. 4 Stroke Oil

You may often hear these two terms, but what are the differences? The former mixes well with fuel and burns it in the engine’s combustion chamber. The latter protects the valve train against wear and tear while keeping it clean. 

Some top companies selling these products are Amsoil, Repsol, Mobil 1, Briggs & Stratton, Pennzoil, and Husqvarna. 

What Happens If You Put 2 Stroke Oil In A 4 Stroke Engine

There will not be any significant damage to your engine if you use 2-stroke grease in a 4-stroke engine. However, some common side effects users encounter are a rise in pipe exhaustion and engine overheating. 

In a recent study, there were no metal contaminations, no real damage to the engine, no compression loss, and no lubrication loss.

HOWTO: How do you mix a 40:1 chainsaw fuel?

A chainsaw typically needs a 40:1 ratio. For safety, we recommend you check the product manual for the specifications. For starters, you need to perform this in a well-ventilated area.

  1. Gather all the materials you need.
    1. UL or FM-approved container
    2. One gallon of gasoline
    3. Three ounces of 2-cycle grease
    4. Chainsaw
  2. Open the UL or FM-approved container and pour 1/2 gallon of the gasoline.
  3. Pour all the grease and close the approved container. Shake it for ten to fifteen seconds. 
  4. Open the container and pour in the other half of the gasoline. Close it again and shake it for another ten to fifteen seconds. 
  5. Uncap the chainsaw’s tank and pour the mixture up to 80% of the tank capacity.
  6. Tighten the cap and wipe off any spills. 

FAQ

2-cycle engine oil

Below are some frequently asked questions. 

What is a 40 to 1 gas mixture?

This mixture contains 128 ounces of gasoline and 3.2 ounces of oil. 

Does 32/1 or 40/1 have more oil? 

A 32/1 contains more oil than a 40/1. 

What happens if the 2-stroke mix is wrong?

A two-stroke mix of gasoline has a short shelf life and will eventually go bad. You do not want to use an incorrect mixture in the two-stroke engine of your chainsaw. Doing so may cause severe, irreversible damage. 

What is the best 2-stroke mix ratio?

Most manufacturers recommend the 50:1 ratio over the 40:1 and 32:1. 

Is 2-cycle the same as 2-stroke?

Yes, they mean the same thing. One cycle equals one stroke, effectively making these two the same. 

How often should you change the oil on a 2-stroke dirt bike?

Changing the grease is absolutely important because it keeps your dirt bike in top shape and performance. We recommend changing it every 5 to 10 hours. If that is not possible, the most are at 15 hours. Anything beyond it makes the engine inefficient.
