What kind of gasoline should I put in my lawnmower?
Unleaded gasoline with an octane value of at least 87 is the finest fuel for your lawnmower (91 RON). Importantly, the gasoline cannot contain more than 10% ethanol (E10 petrol). Too much ethanol in the fuel can attract water, which sinks to the bottom and encourages the growth of germs that corrodes your lawn mower. Your lawn mower shouldn’t be powered by E15 gasoline.
Because it only contains 5% ethanol, most people use “Super Unleaded 97 or 98 RON gasoline in their lawn mowers. In tiny engines like your lawn mower, using premium fuels (such Shell V-Power) has little advantage.
Can you use E10 petrol in a lawn mower?
E10 petrol will power your lawnmower, but it’s not the ideal fuel to use. In general, you want to use fuel that has as little ethanol as possible since ethanol draws water, which can eventually lead to corrosion and engine damage. You can occasionally use E10 gasoline, although 98 RON Super Unleaded is preferable if it’s available where you live.
In the long term, E5 fuel (which has a 5% ethanol percentage) is healthier for your engine than E10, particularly if you have an older lawn mower. With E10 fuel, your mower will perform poorer the older it is, especially if it was manufactured before 2010 or so.
Additionally, be careful not to keep E10 fuel in your gasoline tank for an extended period of time because it might thicken with time.
Honda Lawn & Garden Equipment
Since 1993 YM (year model), Honda Power Equipment has supplied petrol-powered items for the EU market that are all E10 gasoline compliant. This comprises Honda fully assembled units and stationary engines.
What is E10 fuel?
A new fuel specification for gasoline-powered machinery and automobiles is E10. The current ordinary unleaded 95 gasoline allows for the inclusion of just up to 5% ethanol, but the E10 fuel specification allows for the inclusion of up to 10% ethanol. Both fuels meet the same quality standards.
What’s the difference between E10 and current unleaded petrol?
The quality standards for E10 gasoline are the same as those for unleaded 95, but more renewable fuels may be blended into it.
Why are some petrol powered vehicles and equipment not compatible with E10?
When utilizing E10 gasoline, some petrol engines, especially older ones, may experience material compatibility concerns that could impact the fuel system and/or engine of the car or device. E10 cannot be used in products or vehicles with diesel engines.
Where can I find the serial number of my product and what does it look like?
The standard format for serial numbers is a 4 digit letter code followed by a 7 digit numeric code (eg ABCD 1234467).
Can I use the new E10 gasoline with my lawn mower?
E10 fuel only poses a problem with your Mountfield lawnmower if it is allowed to sit inside the machine or is kept in storage for more than 30 days. You won’t likely have any running problems if you simply add the amount of fuel you need and replenish with new fuel every time you use your mower.
However, we advise blending freshly acquired gasoline with Mountfield universal fuel stabilizer to reduce the need for frequent excursions to the gas station. An additive called fuel stabiliser will prevent your gasoline from turning bad for up to two years! Purchase one from our website.
You can also use gasoline with less ethanol, like super unleaded E5, or fuels with no ethanol at all, like Aspen. Find your local authorized MOUNTFIELD dealer here. Many of them carry gasoline substitutes.
Can I fuel my lawnmower with ordinary unleaded gas?
There are several options available if you want to know what fuel lawn mowers utilize. Yes, in the majority of cases, lawnmowers use ordinary gas. But not all ordinary gas has the same octane level. Regular gas typically has an octane rating of 87, which is suitable for all lawn mowers. In any case, I’ll go into further detail below on the properties of each fuel type that can be used in a lawn mower engine.
Do lawn mower engines get damaged by E10 fuel?
Ethanol can draw water and corrode fuel components. Your carburetor’s capillaries may become blocked by ethanol, which will cause issues with your engine. Its corrosive characteristics can harm engines.
Can E5 and E10 gasoline be mixed?
Consult your handbook or get in touch with the maker of your equipment or vehicle if your brand or model is not listed. Car, van, and motorcycle advice may also be available at vehicle MOT garages or workshops. Continue using E5 (97+ octane) gasoline if unsure.
Classic vehicles
Many classic car manufacturers are not included in the vehicle checker. We are unable to provide detailed information on vehicle compatibility in cases where older brands are no longer in business.
E5 (97+ octane) gasoline, which will still be offered in the “super” grade, should be used by owners of vehicles that aren’t included in the vehicle checker.
We suggest getting in touch with clubs and organizations for owners of historic cars, as well as garages that might be able to offer guidance, for further information.
What to do if your vehicle is not compatible with E10 petrol
Use E5 gasoline in the “super” grade (97+ octane), which will continue to be offered at many larger gas stations. Before you fill up, make sure you read the label.
What to do if you put E10 petrol in a non-compatible vehicle
It shouldn’t be a big deal to use one tank of E10 gasoline in an incompatible car. Next time, just be sure to fill it with E5 (’97+ octane) gasoline.
You shouldn’t need to empty the tank, unlike when you add gasoline into a diesel engine. Your vehicle won’t get engine damage as a result once. However, continued use of E10 gasoline in a non-compliant vehicle could be harmful and is not advised.
Mixing E10 and E5 petrol
There is no reason why you can’t blend the two grades of gasoline (E5 97+ and E10 95+) if your car is E10 compliant. If E10 is not available, you can mix the two in the same tank or fill with E5.
Boats, aircraft and other petrol-powered equipment
Other gasoline-powered devices, such as the following, might not work with E10 fuel:
- boats
- petrol-powered lawn and garden tools like lawnmowers and chainsaws
Before operating E10, owners and operators should consult their manual or contact the manufacturer or dealer.
Owners of light aircraft who are currently using E5 gasoline, also known as MOGAS, should keep using E5 gasoline until specifically instructed otherwise by their manufacturer or governing body.
Is E5 fuel suitable for lawn mowers?
You may have come across articles on the new E10 gasoline, which will soon be the norm in UK gasoline forecourts. If you’re wondering what can be used, be assured that most petrol garden machinery goods can run on regular unleaded 98, 95, 95 E5 or E10 gasoline. However, never use gasoline that contains more than 10% ethanol. Fuel system components will suffer corrosion damage as a result of this.
Can I use E10 in my UK Honda lawn mower?
The typical 95 octane unleaded gasoline sold at the pumps now contains 10% ethanol instead of the 5% that it did previously. This modification was made during the summer of 2021 by the government and the fuel companies. They will continue to sell fuel with a lower ethanol concentration of 5%, but only in the more expensive super unleaded variety. These will have E10 or E5 labeling on the pump handle to help you identify them (as shown on the top image).
However, the 10% increase in ethanol content in unleaded pump fuel could exacerbate the effects of unleaded fuel going stale and increase damage to fuel lines and carburettor components like rubber gaskets and diaphragms, as well as cause ethanol deposits to clog the jets inside the carburettor. Ethanol effects in garden machinery are nothing new, and even the 5% ethanol content has been causing problems in recent years as the ethanol in the fuel goes A metal style carburettor’s aluminum casting will likewise deteriorate when exposed to ethanol.
Other small gasoline-powered machinery, such as outboard boat engines, gasoline generators, gasoline-powered construction equipment, classic cars, vintage motorcycles and scooters, and other gasoline-powered vehicles from before the year 2000 will also be impacted by this fuel change. Manufacturers advise against storing or leaving the new standard E10 fuel in an engine’s fuel system for longer than 30 days without a fuel stabilizer and against leaving the E5 super unleaded fuel in an engine’s fuel system for longer than 90 days without a fuel stabilizer. The majority of new small engines built after the year 2000 fitted to garden equipment, generators, and construction equipment will run on the E10 fuel.
The manufacturers still advise using a suitable fuel stabilizer or oils containing fuel stabilisers (two stroke machinery oils) to keep your equipment running at its peak efficiency and to minimize machinery downtime, even if you use your garden equipment or other machinery for daily use and long running periods (contractor, forestry, and grounds maintenance use).
How long will E5 gasoline remain in supply?
E5 will still be available in five years, but only as the protection grade in “super,” according to the Petrol Retailers Association. In five years, it will be evaluated.
Can Briggs and Stratton engines run on E10 gasoline?
For side-valve engines, always use clean, fresh, unleaded gas with an octane value of at least 77, and for overhead-valve engines, at least 85. To keep fuel clean and fresh, we advise using Briggs & Stratton Fuel Fit petrol stabilizer.
Purchase fuel in amounts that you can consume in the next 30 days. By doing this, you can be sure that the gasoline is constantly fresh and that its volatility corresponds to the season. Never combine gasoline with oil.
We highly warn against using gasoline that contains methanol or an E10 blend that has more than 10% ethanol.
How much gasoline do I put in a four-stroke lawn mower?
Mowers with four stroke engines only use unleaded gasoline. Mowers with two strokes use a combination of regular unleaded fuel and a specialized oil. You must combine them in the proper proportion. Mowers with a 2 or 4 stroke engine cost nearly same to purchase.
