A 4 cycle engine takes gasoline as its fuel. The gasoline is mixed with oil, which lubricates the engine’s moving parts. When the engine is running, the mixture of gas and air ignites in the cylinders, creating power that turns the crankshaft.
A four cycle engine is an internal combustion engine that uses four strokes of the pistons to complete one operating cycle. The crankshaft turns twice for every one stroke of the piston, making a ‘four stroke’ sound when running. The four cycle engine is more efficient than the two cycle engine, and produces less pollution.
It runs on gasoline, and requires no oil mixing.

4-Cycle Fuel Vs Gasoline
As you may know, there are two types of fuel commonly used in small engines: 4-cycle fuel and gasoline. Gasoline is the most common type of fuel used in small engines, but 4-cycle fuel is gaining popularity because it is more efficient and produces fewer emissions.
4-cycle fuel is a type of diesel fuel that can be used in any engine that normally uses gasoline.
It is made from a blend of petroleum products and alcohols, and it contains no oxygenates or additives. Gasoline, on the other hand, is a mixture of hydrocarbons that contain oxygenates such as ethanol or methanol.
4-cycle fuel burns cleaner than gasoline because it contains no oxygenates.
This means that there are fewer emissions created when using 4-cycle fuel. In addition, 4-cycle engines are more efficient than gasoline engines because they use all four strokes of the piston to create power. This makes them more powerful and increases their efficiency by up to 30%.
If you’re looking for an environmentally friendly and efficient way to power your small engine, consider using 4-cycle fuel instead of gasoline. You’ll be doing your part to reduce emissions while also saving money at the pump!

What Kind of Gas Does a 4 Cycle Engine Take?
A four-cycle engine requires gasoline with a octane rating of 87. The higher the octane number, the greater the fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In general, unleaded gasoline with an octane rating of 87 is suitable for most four-cycle engines.
Detonation knock is more likely to occur when operating under high loads and/or high temperatures. If you hear knocking, it’s important to reduce the load on the engine and/or increase the speed of the engine to help cool it down. Running too low of an octane gas in your engine will result in increased knocking and potentially serious damage.
Does a 4-Cycle Motor Take Regular Gas?
Most four-cycle engines can run on either regular unleaded gasoline or a less expensive mixture of unleaded gas and oil. The owner’s manual will specify what type of fuel to use. Many newer four-cycle engines are designed to run on only unleaded gasoline.
Do 4-Stroke Engines Take Straight Gas?
There’s a lot of misinformation out there about what kind of gas to use in a 4-stroke engine. So let’s set the record straight: yes, you can use straight gas in a 4-stroke engine. In fact, it’s the recommended fuel for most 4-stroke engines.
Now, there are some exceptions to this rule. If your 4-stroke engine is designed for racing purposes, then you may need to use a higher octane fuel. But for the vast majority of 4-stroke engines, regular unleaded gas will do just fine.
So why is straight gas the best choice for most 4-strokes? It all has to do with the way that these engines are designed. Most 4-strokes have what’s called an “overhead valve” design.
This means that the valves are located above the pistons, as opposed to being located in the cylinder head (like they are in most 2-stroke engines).
Of course, there are other factors that can affect how well your 4-stroke engine runs on straight gas. If your engine is older or hasn’t been tuned properly, it may run better on premium gas. But if your engine is newer and in good condition, regular unleaded should be just fine.
Can You Use Mixed Gas in a 4 Cycle Engine?
Yes, you can use mixed gas in a 4 cycle engine. You’ll just need to make sure that the ratio of gas to oil is correct. For example, if your engine uses a 50:1 mixture, you’ll need to add 2.6 ounces of oil for every gallon of gas.

Conclusion
Most 4 cycle engines require either regular unleaded gasoline, or a mix of regular unleaded gasoline and oil. The gas to oil ratio for these engines is typically 50:1, meaning that for every 1 gallon of gas, you would add 2.6 ounces of oil.
