E5 gasoline consists of 95% unleaded gasoline and 5% ethanol (hence the name “E5”).

Moreover, E10 is the modified version of E5 petrol. It is much more environmentally friendly, containing 10 percent ethanol and 90 percent regular unleaded gasoline.

This modification results in the reduction of our vehicle’s CO2 emissions. E10 gasoline can even cut vehicle CO2 emissions by 750,000 tons per year. It’s similar to taking 350,000 vehicles off the US roads.

Replacing E5 gasoline with E10 is confusing for many motorists. However, the Government raised E10 gasoline to reduce exhaust emissions. So, using E5 and E10 petrol for the lawnmower is better.

Benefits of Using E5 Petrol In Lawnmower:

E5 petrol has different benefits from the environmental and economic point of view. Let’s have a look at them!

●      Ensure Energy Security

The development of biofuels helps a country to be active in fuel imports, especially in countries that do not have a source of oil and coal.

Also, it limits the rise in oil prices and energy resilience worldwide. The biofuels produced from massive biomass from renewable materials will become a priority option for ensuring countries’ energy security.

●      Economic Development in Rural Areas

Biogas comes from ethanol and gasoline used for internal combustion engines like cars and motorcycles.

Bioethanol is blended with biofuel to replace oxygenated compounds added to gasoline. You will get it through the fermentation of molasses, starch, and other farming waste.

Ethanol plants using cassava as raw material will support cassava producers’ stable production. It is estimated that each plant can be put into production when about 15,000 cassava-planted houses in Vietnam’s west, north, and southeast highlands have been stabilized.

Expanding biofuel use protects the environment. Also, it contributes to positive changes in people’s lives in remote areas.

●      Protection of The Environment

CO exhaust is very toxic, and its emissions in motorcycle engines are incredibly high. Moreover, the E5 biogas engine produces very low HC and CO emissions, around 20% less than A95 and A92 gasoline. So, the E5 biogasoline is highly ecological.

In addition to significantly reducing HC and CO gas components, vehicle acceleration is better for E5 biogasoline.

The combustion process for E5 petrol is improved for a more uniform mixing of fuel and air for the potentially good E5 bio evaporation.

What Fuel Should I Use in My Lawn Mower?

The choice of gasoline for your lawn mower mainly depends on your engine type. Maximum 4-stroke engines utilize fresh unleaded petrol with 87% octane or higher. You can use gasoline with up to 10% ethanol content.

Two-stroke mowers use reenergized unleaded petrol with 87% octane or higher. Also, you have to add high-quality two-stroke engine oil. Thus, they may run on regular or superior gasoline.

As a rule, lawn mowers should use clean and fresh gasoline. Also, it should contain no more than 10% ethanol and 87% octane.

While you may purchase regular lawnmower gasoline at the local gasoline station, it is recommended that you only use fuel containing up to 10% ethanol. Don’t use 85% ethanol as it is unsuitable for small engines like gas lawn mowers.

Is E10 as Good as E5 in Lawn Mower use?

Overall, switching to the E10 won’t impact much and may even save them money. Moreover, E10 is more affordable than E5 because E5 petrol has become premium gasoline, and E10 is priced the same as typical unleaded gasoline.

The UK governance sets fuel economy at 1% with E10 over E5. Therefore, most drivers will not notice the change, which should only significantly impact more innovative car drivers.

There are different issues with the E10 to watch out for. E10 is less stable than E5, which can cause starting problems in some cars. Also, you may have to deal with large fluctuations in gasoline prices, and E10 is affected by both the oil’s wholesale price and the crop’s wholesale cost.

So most drivers will use E10 petrol without even knowing it. In our opinion, now is the right time to use E10 fuel to keep your lawnmower engine running and get the most out of every fuel drop into your tank.

Is the new E10 Fuel Reducing Fuel Efficiency?

E10 produces 96.7% of gasoline energy, less than 0.6% of the E5 petrol. As I mentioned above, E10 has been introduced to reduce CO2 emissions. Its CO2 emission rate is 18.94%.

On the other hand, both gasoline and E5 petrol have a higher CO2 emission rate than E10 petrol. In terms of pricing, the cost of pure gasoline and E10 petrol is higher.

But you will get better performance from the E10 petrol at a lower price. On this occasion, E10 petrol reduces fuel efficiency.
