What gasoline and oil to fill a lawn mower
A self-propelled gasoline-powered lawn mower is a sophisticated piece of equipment that can mow grass, as well as perform other functions. Because it is equipped with a motor, it can also be used by physically weak people. This technique requires regular maintenance. One of the necessary procedures is to change the oil. Everyone who has such a device, should know what gasoline to pour into the lawnmower. It is necessary to know how to choose the right fuel for your model, it can be AL-KO (AL-KO), DAEWOO, Honda (Honda), Husqvarna (Husqvarna), Patriot (Patriot), Stiga, Champion, etc.Д.
4-stroke engines have a more complex design than 2-stroke engines. Four-stroke mowers are more powerful, so they are more efficient. These engines are more economical. Run cleaner because they have fairly good control of the air intake and exhaust cycle.
With the two-stroke cycle, because fuel goes out during feeding and compression, some of it is wasted. This does not happen with the other engine, but there is petrol injection in a closed system. 2-stroke engines can be filled with petroleum mixtures. Which reduces the combustion efficiency, increases emissions in the form of burnt harmful oil. Fuel and oil mix in them, it has a negative effect on the service life. Because of general circulation these lawnmowers can be operated in all conditions.
4-stroke engine has a specialized lubrication system. In this engine, the engine oil is injected from a separate container. The oil is separate from the fuel. So the motor is better lubricated. Automotive engines tend to operate on the four-stroke cycle.
The simple design and fewer moving parts in a 2-stroke brushcutter makes maintenance and repair easier. They are much lighter.
Cleaner operation of four-stroke engines and a special lubrication system results in less wear and tear and longer life of such equipment.
Due to the dirty combustion product after fuel and oil combustion in two-cycle engines, there is more wear and tear on the engine system. As a result, it fails sooner. The cost of a lawn mower with this engine is less, but it increases per hour due to the extra cost of oil and the low fuel economy.

Choosing lawnmower oil
Every summer starts the season of intensive use of gasoline equipment. Even in our country in recent years have become actively used lawn mowers, we previously known only from TV movies.
Of course, that the users of such a tool has a lot of problems, because not everyone has experience in its proper use. In particular, a particular headache is the oil for lawn mowers, the choice of which is not so simple. By the way, it would not be out of place to say that many customers set themselves radically wrong criteria for selecting lubricants, because they have little idea of the basic performance characteristics of the equipment they use.
They often forget that even lawnmower oil should be chosen according to ambient temperature parameters.
It is known that any lubricant for four-stroke engines must meet certain viscosity indexes SAE. Of course, lawn grass grows very poorly at sub-zero temperatures, so when buying, you should focus on those products, whose indicator in this parameter corresponds to the summer operation.
Most manufacturers say that the optimal oil for lawn mowers will be SAE 30. The use of less viscous varieties for cold climates and thicker greases for hot regions is also not welcome. Why?
It is the construction of these devices. To make them cheaper and easier to produce, the designers have excluded the oil pump from their composition. As a result, all moving parts of the engine are lubricated thanks to the crankshaft which during its movement “scoops it up” from the crankcase, distributing lubricant evenly by friction over all parts. That’s why you shouldn’t buy lawn mower oil at the first place you see, because you might end up with a bill for its repair.
So if the lubricant is too thin, it will simply flow from the crankshaft back into the crankcase. If it is too thick, then over time, such a substance can turn into an amonous solid mass, which also will not lead to anything good.
Automobiles are much better protected from such troubles, because a special oil pump is responsible for the evenness of engine lubrication. Theoretically, all lawnmower oil can be used in cars, but standard products for cars will not always suit other equipment.
Luckily, nowadays almost all specialized retail chains sell specialized SAE 30 class grease. Except that not all cities have such outlets, not to mention smaller towns. So what oil to pour into the lawnmower in the absence of specialized options?
Specialists say that SAE 15W-40 and SAE 20W-50 class greases are best suited for this purpose. It does not matter much whether you buy synthetic or mineral oil since lawn mowers are not used in as tough conditions as race cars have to go through.

Which mower to choose?
To summarize, choose which machine is best to buy for your own yard. Self-propelled devices are suitable if:
When buying take into account that the maintenance of drives will also cost a lot of money, while in non-self-powered units are easy to change on their own, if you have at least a minimal understanding of the device.
If budget is the first choice criteria, give preference to the non-self-propelled model.

Suitable for small and flat areas, as well as for those who like to take walks in the fresh air and are physically strong enough to cope with a heavy appliance.
Types and principle of operation of lawnmowers
The principle of lawnmowers is the rapid rotation of metal blades with two directional blades. The movement of the blades of grass creates an airflow that lifts the stalks vertically. The cutting side of the blade, like an airplane propeller, trims the grass to a predetermined size, creating an even and high-quality coverage.
Mowers can be either self-propelled or non-propelled.
Non-self-propelled mower requires certain efforts from the owner and is designed to work only on perfectly flat areas. A non-self-propelled lawn mower can be a great trainer for the owner, in other situations it is better to choose another option, as a non-self-propelled mower will not work on a sloped or bumpy area.
Self-propelled petrol lawn mowers travel autonomously and are ideal for inclined and uneven areas. On top of that, the weight of the tool is so impressive that it can mow quickly and easily and cover a large area.
Self-propelled lawn mowers differ in the type of drive:
Front-drive tools are more maneuverable, rear-drive ones work well on bumpy terrain.
Selection parameters. Blades
Two blades come standard: one for mowing and one for mulching. When choosing mowers pay attention to the quality of the blades that should be well sharpened and have a high rotation speed. The blades of the mower should be cutting the stem, not ripping it, otherwise it will produce the disease of the lawn and alopecia.
Strong vibratory impacts of blades can upset the natural balancing of the tool that will inevitably lead to the failure of the bearings and bushings of the wheels and engine.
Gasoline self-propelled mower must have a blade for mulching, which not only cuts but also shreds the grass, and then distributes it evenly over the lawn, creating an excellent seasonal fertilizer.
Selection parameters. Engine power
The choice of motor power is also an important parameter, because low speeds can handle a flowing lawn, but mowing tall or dense grass will be problematic. At high loads, the engine may stall at all and you will have to clean the sharp blades of blades from the grass stuck there.
To determine the correct power, the store consultant will need to specify the approximate area to be treated and the degree of density of the lawn. If the area of the site is large and mowing needs to be frequent, then it is best to choose garden tractors or riders.
Selection options. Height adjustment, band width
The width of the bevel bar depends on the number of passes, working time and fuel consumption. The standard self-propelled petrol lawnmower has a cutting height of 33-43 cm, the professional equipment has a cutting height of 43-55 cm.
The height adjustment of the bevel can be as follows:
- The easiest and most reliable variant is the regulation installed in the body itself with a vertical row of holes.
- Central lever height adjustment.
- Independent adjustment of each wheel.
For frequent work it is best to choose a central or independent adjustment system.
Selection parameters. Wheels and housing
The most inexpensive and popular material for the housing is impact-resistant plastic, which, even with deep scratches, does not affect the operation of the mower.
Reliable and powerful is the steel body, which should be protected by a special anti-corrosion coating.
Aluminum housing is also popular and used for self-propelled tools.
Gasoline self-propelled lawnmower must have a large diameter of wheels, so that the device can easily move over bumpy terrain. Wheels with bearings or wheels with bushings are more practical.
What petrol to fill up
Gasoline for the lawnmower is the second element of the fuel mixture. Its brand should be chosen according to the manufacturer’s recommendations described in the machine’s data sheet. On the duration of fuel combustion and resistance to detonation indicates the octane number: the higher the number, the longer the fuel burns. Thus, at gas stations you can buy such grades of petroleum products:
AI-92 is more prone to detonation.
The mixture is prepared before use in the proportions indicated on the petrol tank lid:
This means that 20 ml of oil fluid is needed per 1 liter of fuel.
Manufacturers of two-stroke petrol mowers (e.G., Patriot PT 555 or Champion T336) give the correct fuel mix ratio in the instruction manual. The ratio is 32:1 for the first model and 50:1 for the second model.
Lawn mower with 4-stroke engine does not require any pre-treatment. There are 2 tanks in the device. Gasoline must be filled into the tank and lubricant into the drain in the crankcase.

Lawnmowers and lawn mowers. Fuel mixture preparation. Changing the oil in the lawnmower engine | Do-It-Yourself.Ru
When choosing a means to care for the grass in the garden or dacha site, the owner faces the choice. What to buy. A lawnmower (electric mower) or a wheel mower.
The abundance of information on the Internet and advice from sellers makes a perfect mess in the mind of a potential buyer, based not only on experience (including negative), but also on prejudice and outright ignorance.
The lawnmower is only for strong men! (like schwarzenegger).
Lawn mower is a two-stroke gasoline motor with a capacity of 1-2 liters.С., located on one end of the tube. And at the other end. A cutting element, a disc or a spool with a fishing line. The total weight of this device is several kilograms. The suspension point is designed so that even a fragile girl can handle a chain saw. The grasshopper is very well balanced.
Fueling two-stroke engines and preparing the fuel mixture are wonders of alchemy, inaccessible to mere mortals
Two stroke engines don’t just require gasoline for their power, but a fuel mixture of gasoline and oil (special, for two stroke engines). This is not a deficit at all, oil for two-stroke motors is sold in any auto parts store and any place where these very lawn mowers are sold Ask the salesman and he will take you to the shelf with these oils. Your eyes will be dazzled by the choice.
To make a “gasoline-oil” mix is no more complicated than dressing a salad with mayonnaise. As a rule, the oil to gasoline ratio (1:32 to 1:35) is indicated on the scythe (or chainsaw). That’s the ratio for mineral oils.
You can’t find those oils for two-stroke engines, except for motorcycle engine oils. For small packaged oils for gardening equipment. Practically only synthetic oils. And they have a 1:50 ratio (which is usually written on the package).
You have to follow the recommendations on the oil packet!
To make fuel mixture, you take a fuel can, for example, of 5 liters of petrol and fill it with 100 ml of oil. That’s the whole secret. You’ll have enough oil for the whole season. If it is not enough. Repeat the procedure Pour this mixture into petrol tank and no more problems.
You have to buy only “Husqvarna” oil for your Husqvarna lawnmower
Husqvarna does not have its own refineries. It’s a different business.
So she buys oil for two-stroke engines at the refinery in tanks, packs it in small cans and glues a tag “Husqvarna” And she beats the ignorant extra 2-3 for this tag.
Another company, like STIHL, buys the same oil from the same factory and puts a “STIHL” label on the bottlesand they charge 2-3 bucks for the fools too Any two-stroke oil is good for any two-stroke engine!
Wheel mowers are only for perfectly flat lawns.
Not at all I thought so, too, on my completely unplanned area. Turns out that a wheeled gasoline mower is great at rounding the terrain. The only obstacle is anthills that can be removed with a shovel.
But a wheeled mower handles rough terrain perfectly. Especially if it has a mowing height adjustment. You set the maximum. And “test” the area.
Where the blade grips the ground, you may also work with a shovel.
The lawn mower has several times the cutting performance of a hand lawn mower. And to drive it is not more difficult than to roll a baby carriage. You just walk over and guide it. Especially if the mower is self-propelled. Even children can manage it.
Wheeled lawnmowers have a 4-stroke engine and their maintenance is as complicated as a car.
Wheel mowers usually have four-stroke engines. The principal difference between a four-stroke and a two-stroke engine is the presence of a crankcase with oil for engine lubrication. That’s why you don’t need to make a fuel mixture of oil and gasoline for a 4-stroke engine to work properly, you only need to fill the gas tank with gasoline.
This circumstance is presented by some dishonest sellers as an advantage. “they say that it is not necessary to bother with preparation of fuel mixture”. In doing so, they “nicely” overlooked such a detail as the need for at least an annual oil change in the crankcase of the wheel mower.
The procedure is not complicated, much easier than changing oil in a car, but more complicated than preparing the fuel mix. Generally speaking, the oil in the crankcase of a wheeled lawnmower needs to be changed about every 50 hours of operation. The lawnmower has no oil filter and therefore the oil is not cleaned there. That is why the oil is changed more often.
On the other hand, 50 hours of mower operation in a season is a very long working hours.
The process of changing the oil in a ride-on lawnmower is not complicated. Before changing the oil it is advisable to let the mower run for about 10-15 minutes to let the oil warm up and become more fluid.
Each lawnmower has a special screw that covers the drain hole from the engine crankcase. It is usually located under the oil filler neck and measuring cup of the housing. (marked with an arrow in the photo).
Mower is installed with a slope towards the drainage hole, placing a block of wood or a brick under the housing on the opposite side. After that the screw. Plug is unscrewed. In order not to spill oil on the lawnmower housing, a chute is cut out of a plastic bottle, along which the oil will flow into the container placed underneath. Before changing the oil it is desirable to exhaust the gasoline from the gas tank.
After that they unscrew the plug and let the oil drain out by tilting the lawnmower. When the oil has drained out, the screw is screwed in place. Fill in fresh oil via the measuring cup. Generally recommended oils for lawnmowers are 10W40, mineral or semi-synthetic.
The inexperienced owner of a garden motor, of course, tends to almost idolize the new purchased equipment, up to the point of fetishism. He wants to fill it with better gas and more expensive oil. This is a typical mistake that leads to a very rapid failure of the technique!
