If you’re a snowmobiler, chainsaw user, or dirt biker, then you know the importance of using the right type of oil in your engine. 2-stroke engines are popular among these types of riders because they are more powerful and lightweight than 4-stroke engines. However, using the wrong type of oil can lead to performance problems and engine damage. In this article, we will discuss the benefits of using Saber synthetic 2-stroke oil and provide examples of engines that require 2-stroke oil to run properly. We will also provide tips on how to care for 2-stroke engines during the offseason.
Benefits of Using Saber Synthetic 2-Stroke Oil
2-Stroke and 4-Stroke Engines: What's the Difference?
While both 2-stroke and 4-stroke engines rely on the same basic principles of combustion to power the motor, a 4-stroke engine goes through four stages of operation before completing one power stroke while a 2-stroke engine only goes through two. A 4-stroke engine also undergoes two complete revolutions before the power stroke is finished.
So what are the “strokes” that 2-stroke and 4-stroke engines are referring to? A “stroke” is the term for when the piston moves from the top of the engine’s cylinder to the bottom. While it makes this movement, it gathers the oxygen and gas necessary for combustion; when the piston is shot back to the top of the cylinder again, the exhaust valve opens to remove the exhaust from the combustion. There are five phases of the combustion cycle: intake, compression, ignition, combustion, and exhaust.
Essentially, 2-stroke engines combine more phases during each piston movement versus the traditional 4-stroke method. With 2-stroke engines, when the piston moves up, it compresses the air, fuel, and oil in the combustion chamber; while the piston is at the top of the cylinder, a new mixture of air, fuel, and oil is pulled into the airtight crankcase.
4-stroke engines work at a different rate. It takes four events (or movements up or down of the piston within the cylinder) to complete a single power stroke.
What's the Difference Between 2-Stroke and 4-Stroke Oil?
2-stroke engines rely on “mixed” fuel for the combustion process—that is, a mixture of fuel, air, and oil. 4-stroke engines, in contrast, rely on motor oil for lubrication purposes only, and the fuel is kept entirely separate. 4-stroke oils also tend to contain more additives than their simpler 2-stroke counterparts.
What Kinds of Engines Need 2-Stroke Oil?
You might be aware that automobiles are a common example of a 4-stroke engine—but what kinds of motorized equipment or vehicles rely on 2-stroke oil? Some common examples of motors that require mixed 2-stroke fuel include:
· Chainsaws and other outdoor power tools like blowers or trimmers
· Some motorcycles
· Some lawn mowers or weed eaters
· Some outboard motors
Pros and Cons of 2-Stroke Engines
If a 2-stroke engine can accomplish combustion at a faster rate than a 4-stroke engine does that mean that it’s the superior design? Well, it turns out the answer is a little more nuanced than a simple “yes” or “no.” In the following section, we will detail some of the benefits of a 2-stroke engine as well as some of the downsides.
Benefits of 2-Stroke Engines
There are many positive aspects of 2-stroke engines that keep them on the market even with competition like electric or battery-run alternatives. Some of the pros of 2-stroke engines include:
· They tend to be more cost-effective than 4-stroke engines
· They tend to be more compact and lightweight than 4-stroke engines
· Due to the design, there is less friction on the moving parts and therefore better efficiency
· 2-stroke engines can operate in all kinds of weather—hot and cold
· It takes one power stroke for each revolution of the crankshaft which makes for an even turning movement
· The engine has exhaust and inlet ports
· The design is simpler, so there’s less to break or go wrong
Downsides of 2-Stroke Engines
With all the upsides of a 2-stroke engine, there are some areas where a 4-stroke engine has got it beat. Here are some of the cons associated with a 2-stroke engine:
· They consume more fuel than 4-stroke engines
· They produce more emissions because they burn oil, which is not great for the environment
· They typically are loud and prone to heavy vibrations during use
· Because it does what a 4-stroke engine does under a condensed timeline, 2-stroke engines tend to have a shorter life span due to engine wear
· 2-stroke engines may be hard to keep at an idle
· 2-stroke engines have a narrow range of speed in which the engine is at its peak performance (this is called the “power band”)
How to Care for 2-Stroke Engines in the Offseason
While marine and outboard motor winterization might look a little different, for basic 2-stroke engines you might have around the house, such as lawn maintenance equipment, there are several basic steps to follow to ensure your tools are put away in good condition and will be ready for use next time you need them.
1. First, ensure you are working in a well-ventilated area. Wipe debris from the fuel cap with a shop towel to prevent any unwanted material from contaminating the fuel mixture.
2. Then, drain the fuel tank into a gasoline container using a funnel. Make sure the gasoline container is labeled “mixed fuel” or “2-stroke.”
3. After you’ve drained the fuel tank, add a small portion of premixed 2-stroke fuel to the tank, cap off the motor, and remove any closed gasoline tanks from the area. Then, start the engine and run it at an idle until it is completely out of fuel.
4. Allow the engine to cool before storing it in a dry area.
And there you have it! Winterizing your 2-stroke engines can even be a little bit fun and ensures that you are taking the best possible care of your tools so that they start back up for you again without hesitation come springtime.
Benefits of Using Saber Synthetic 2-Stroke Oil
There are many different kinds of 2-stroke oil on the market—so which one should you choose?
Well, there are many benefits of using Saber Synthetic 2-Stroke Oil over other types of lubricants out there. In fact, Saber Synthetic 2-Stroke Oil offers users fewer emissions at fuel-to-oil ratios of 80:1 and 100:1. Also, it takes less oil to mix with a gallon of gas than some of the 2-stroke oil competitors, as you can get one gallon of 100:1 fuel out of 1.5 oz of oil. Saber also offers superior lubrication and helps to prevent premature wear, so you can increase the lifespan of your 2-stroke motor while helping it reach peak efficiency. Additionally, there is no need for fuel stabilizers when using Saber Synthetic 2-Stroke Oil, so please use ethanol-free gas when mixing your 2-stroke fuel at home.
