Regular Vs Premium Gas For Lawn Mower
The differences in quality between gasoline and ethanol fuel have been a concern for lawn mower manufacturers, operators, and repair technicians since the early 1990s. One-quart companies have been confronted with service questions from owners of small engines about dealing with problems caused by using gasohol or regular unleaded gasoline in their equipment. The service problems include engine surging and hard starting in cold weather.
The most common question we get is whether using premium unleaded gasoline will improve performance. The answer to this question is yes, premium gas will make your small engines run better because it usually has a higher octane rating than regular-grade fuel. However, premium fuel does not contain any more energy per gallon than regular-grade gas, so the cost is not justified for most people.
Unlike small engines, high-performance cars are designed to run on premium unleaded gasoline because they have higher compression ratios that require a higher octane rating to prevent detonation or knocking. The octane rating of gasoline is an index of its resistance to an uncontrolled ignition. An octane number greater than 100 indicates that fuel can withstand more compression without detonating.
Can You Use E10 Petrol In A Lawn Mower
Your lawn mower will run on E10 petrol, but its not the best type of fuel to use. Ideally, you want to use fuel with as little ethanol as possible, because ethanol attracts water, causing corrosion and possible engine damage over time. You can use E10 petrol occasionally, but 98 RON Super Unleaded is a better choice if you can get it where you live.
E5 fuel is better than E10 for your engine over the long run, especially if you have an older lawn mower. The older your mower, the worse it will perform with E10 fuel, especially for lawn mowers made before 2010 or so.
Also, ensure not to leave E10 fuel in your petrol tank for extended periods, as it can begin to go thick over time.
Fresh Gasoline Is Compulsory
Other than the mixing ratio I have mentioned above, mixing fuel stabilizer with fresh gasoline is very important. If you mix it with gasoline more than one month old, the gasoline may already be broken. If this happens, the stabilizer will not come into much use. So, try to mix the stabilizer with freshly bought gasoline to make the best use of the fuel stabilizer.

Measure The Stabilizer And Add It To The Tank
Now that the fuel tank is empty, its time to measure out the correct amount of stabilizer. For 2 gallons of fresh gasoline, most brands recommend adding one ounce of fuel stabilizer.
If there is no measurement on the bottle, you can use a measuring spoon. Before adding fresh fuel, make sure the tank is stabilized.
Is It Okay To Use Premium Gas In A Lawn Mower
You can certainly use premium high octane gasoline in your lawn mower. However, it is recommended that you check your mowers manual before using premium gas.
Most engines are designed to use minimum octane-rated gasoline, therefore anything higher than that can easily damage the fuel system of the mower. Additionally, in most cases, there are no benefits yet premium gas costs 5 to 20 cents per gallon more than regular gas. You need a higher compression ratio to get any advantage out of higher octane numbers.
That being said, there is no harm in using premium gas in your lawn mower but dont expect that it will improve your mowers performance.

Regular Or Premium Gas For Lawn Mower
Premium gas has a higher octane rating, indicating less filler in the gas, making it considerably purer. Lawn mowers can usually run on lower-grade fuel thus, premium gasoline isnt always required. Furthermore, higher-grade gasoline has fewer additives, resulting in less build-up in your lawn mowers engines.
Like any other item, your lawn mower may be valuable to your toolkit. In addition to cleaning and undercarriage maintenance, your lawn mower may require frequent oil changes and gas refills. All of this, on the other hand, is rather ordinary. Is my lawn mower compatible with Premium gas? Its a good question to consider. There are opposing viewpoints on the premium gas utility in mowers on both sides of the aisle. We will look at the difference in this post.
To Help Prevent Water Contamination Problems When Using A Gasoline/ethanol Mix:
- Keep your fuel tank and fuel storage tank filled with fresh fuel and out of direct sunlight.
- Don’t purchase more fuel than will be used in a 3-month period.
- Use a fuel stabilizer along with fresh fuel when your engine is stored . Note that a fuel stabilizer will not reconstitute stale fuel.
- Use a gas station with a reputation for quality fuel.
- Know the specific fuel laws for your state as laws and fuel composition may change often.

Is 95 Petrol The Same As E10
Petrol types in Australia. Standard petrol is given a 91 rating, while premium unleaded is both 95 and 98. There are also two ethanol-based fuels E10 and E85 which are potentially more environmentally friendly options. as they use a corn or sugarcane based ethanol blend, instead of 100% refined oil.
Do Lawn Mowers Need Premium Gas
Should you buy regular or premium gas? Most lawn mowers, and most four-stroke engines, do not need premium gas, or high octane rating like premium 93 octane fuel. Most mowers will run fine with a regular 87-90 octane rating. However, you should always check your manufacturers manual for your models exact engine specifications as it may require higher octane numbers. Using a higher octane rating fuel in your regular lawnmower will not make it run smoother or give it more power. It can get costly especially if you run a lawn mower with increased fuel consumption and power like a ride-on tractor.

What Do I Do If I Left The Gas In My Lawn Mower
If the amount of gas in the tank is small and its not broken down into a thick gum, you could add some fresh gas. It is possible to get the old gas out of the system if the mixture is more fresh. You can do this by opening the fuel filler cap and looking at the bottom of it. This is a good sign that the mix is fresh and not stale.
The Best Fuel Type And Octane Rating For Small Engines
I’m a man who likes quality, but spending more money for something doesn’t always mean it’s better.
When you fill up your car at the gas station, there are usually three different types, or grades of gasoline to choose from. Often, youll see Unleaded, Midgrade, and Premium. Each will have a number, typically ranging from 87-92.
If youre unfamiliar with what these octane ratings mean, you might pay extra for premium gas, thinking it sounds better. The same goes for filling up your lawn mower, snow blower, or other gasoline-powered equipment. Maybe you think youll get better efficiency, but thats largely a myth unless your manual specifically calls for it.
In this article, we’ll talk about everything you need to know about gas and your small engine.

Regular Or Premium Gas For Lawn Mower Which Is Better
To get the best performance out of your lawn mower engine, you must use fresh, clean fuel that contains a gas stabilizer. Remember that most fuels made from ethanol will degrade over time and can cause a lawnmower engine to start and operate poorly. So which gas is best for lawn mowers, regular or premium? Regular unleaded gas with a minimum octane rating of 87 and less than 10% ethanol is used in lawn mowers with both 2-stroke and 4-stroke engines. Lawn mowers with 4 stroke engines used sae30 and 10w30 gas and it is recommended by manufacturers too. Its also possible to utilize premium gas with a higher octane rating, such as 91 or 93.
Regular or premium gas coupled with appropriate two-cycle engine oil can be used in two-cycle mowers. Ethanol concentration is also important. Ethanol can absorb moisture, which can cause problems with your carburetor then you have to locate the carburetor of a mower and fix it. Your fuel mixture is recommended to contain no more than 10% ethanol. Otherwise, you may have problems while trying to start your lawnmower. In general, ethanol can be dangerous but is not a concern if you use the fuel frequently and do not use it for a long time. I like this non-ethanol fuel for four-stroke engines. It is pre-mixed and can be used in outdoor electrical equipment.
Verdict: Type Of Gas To Use In Your Lawn Mower
Most mowers take regular gas, but there are superior options. Plus, some mowers have very specific fuel requirements. If you use the wrong type of gas in your lawn mower, you can ruin it and end up needing to purchase a new one sooner than youd planned.
Fortunately, there are several fantastic options available. Generally, the best type of gas to use in your lawn mower is high-octane, unleaded, non-oxygenated gas with no ethanol. However, regular unlead gasoline usually works fine, and its always best to check your users manual before making your gas choice.

Can I Just Use Premium Gas In My Lawn Mower
In general, theres no reason you shouldnt use premium high octane gasoline in your OPE, but make sure to check in your owners manual just to make sure.
Using a higher grade fuel will not harm your engine, but dont expect to see much in the way of performance boost with premium gas.
Its certainly not worth the extra 5 to 20 cents per gallon you will probably pay over regular gas so unless your machine needs it, then its probably not worth it.
Most mowers are set up to run on regular gas rather than premium grade fuel but check with the manufacturer to make sure as some engines may have a higher compression ratio that requires the higher octane ratings found in premium gas for optimal performance.
How Do You Know If Gas Has Ethanol In It
Ethanol-free gas is usually labeled as E10, E15, or E85. Ethanol-free gas is typically labeled with an ethanol-free sticker or a label that says zero percent ethanol.
If youre not sure of the content of your lawn mowers fuel tank and youd like to use ethanol-free gasoline, ask the gas station employee before filling up your lawn mowers fuel tank.

The General Assumption About Premium Gas For Lawn Mowers
The word premium tends to imply that something is better. Especially compared to something labeled as regular. The general assumption is that a premium is of higher quality and will lead to increased engine lifetime, decreased emissions and better performance.
In reality, you wont get any of these benefits from using premium fuel in your mower. You certainly wont get more power from using premium gas!
In the context of fuel, how well a particular type functions depends on the type of engine its being used in. If you tried to run a high-performance engine on too low of an octane fuel, the engine will not as well as it possibly could. Luckily for you, your lawn mowers engine is not a high-performance engine. An engine thats designed to run on regular fuel isnt going to see any benefit from using a higher-octane option.
The overwhelming majority of car engines in the US need regular gas. The only reason to purchase fuel with a higher-octane rating is to prevent knocking on high performance engines.

Do Lawn Mowers Use Regular Gasoline Or Do They Utilize Something Else
There are several options available if you want to know what fuel lawn mowers utilize. Yes, Mowers often take regular gas. But not all ordinary gas has the same octane level.
Regular gas usually has an octane rating of 87, which is suitable for all lawn mowers.
Anyhow, Ill go into further detail below on the properties of each fuel type that can be used in a lawn mower engine.

What Is Ethanol Free Gas And Why Is Ethanol Bad For Your Small Engine Outdoor Power Equipment
Ethanol fuel, a gas additive, is everywhere! Nowadays, the gas you pump from almost every gas station contains a blend of gasoline and ethanol. The percentage of ethanol blend is indicated by the E number. For example E10 means the gas mixture contains 90% gas and 10% ethanol. In automobiles, ethanol fuel wont do much harm to your car’s engine. However, when you’re using gas with ethanol mixture in your outdoor power equipment, like lawn mowers, chainsaws, trimmers and leaf blowers, you run the risk of engine damage and incurring costly repairs. You should be using ethanol free gas in your small engine outdoor power equipment.
Drain All Old Fuel From The Fuel Tank
Before adding fresh fuel to your lawn mower, drain all of the old fuel from the tank. If you dont, the new fuel will mix with the old and cause problems. To drain the fuel:
- First, disconnect the spark plug wire so the engine cant start accidentally.
- Next, tilt the mower to raise the carburetor rather than the fuel tank. This will allow any remaining fuel in the carburetor to drain back into the tank.
- Finally, remove the fuel cap and let the tank empty into a container for disposal.
Once the tank is empty, you can add fresh fuel and be confident that your lawn mower will run all season smoothly.

The Dangers Of Stale Petrol
To keep your mower running smoothly, the lawn mower fuel you use must be fresh. Old petrol can become stale in as little as a few weeks if left in contact with the air. Using stale petrol in your lawn mower can result in poor performance, will make the engine run rough, and may make the lawn mower difficult to start with the starter cord.
Petrol can also become stale inside the lawn mower engine. After your finish mowing your lawn, its a good idea to clear any petrol out of the engine and fuel system if the fuel is stored in the fuel tank, it wont become stale as easily as it does inside the engine itself.
To clear fuel out of the engine when you finish mowing, switch the fuel valve to the off position and start up the motor. Leave it running for a few minutes until it cuts out when it stops, this means that all the fuel has been purged from the carburettor and fuel system.

What Fuels Should You Avoid Using In Your Lawn Mower And Why Should You Avoid Them
Although many different fuels can be used in lawn mowers, some do not work well with lawn mower engines. The following two fuels ought to be avoided.
High Ethanol Content Gasoline Blends
Nearly all gasoline in the United States includes up to 10% ethanol, however, many people are unaware of this.
Regular, mid-range, and premium unleaded gasoline all fall under this category.
Any fuel that contains more than 10% ethanol is labeled differently, such as E15 for 15% ethanol or E85 for 85% ethanol.
Even though these fuels have their applications, it is not a good idea to use these fuels in your lawn mower. Since fuels with a high ethanol percentage can cause corrosion, small engines and high ethanol fuels dont get along.
Diesel
This might go without saying, but diesel fuel should never be used in a gasoline engine .
If you put diesel in your lawnmower, youre going to get into a lot of trouble, and you might not be forgiven by your small engine mechanic.
When youre at the gas station, make sure to double verify the fuel youre pumping.
