Gasoline for lawn trimmers. what to choose and how to dilute?
You’ll need gasoline grass trimmers to cut the grass in the garden or in the field. They work on gasoline, unlike their electric counterparts. How to dilute gasoline with oil for trimmers, petrol and brush cutters, not many masters know. Step-by-step instructions on how to prepare the fuel mixture in the trimmer for grass will be useful not only for beginners, but also for specialists, who may refuel gasoline saws incorrectly.
Requirements to the oil
The mixture of gasoline and oil, selected for brushcutter, must meet the necessary requirements specified in the instructions. It is important to note that domestic manufacturers often label their products slightly differently from the American or Japanese classification. Russian lubricant manufacturers, as a rule, put marking 2T on all oils intended for two-stroke engines. It is not rare to find oil cans marked “self mix” or “pre mix” on the shelves. In the first case, this means that the oil does not require any additional manipulation; simply pour the gasoline and oil into the same container, and mixing will occur without human intervention. In the second case, respectively, you will have to shake or shake the mixture to bring it to the right consistency.
As you can see, the existence of different classifications of lubricants suggests that the use of oils in two-stroke engines is necessary. This is due to the fact that the fuel mixture without lubricant pretty quickly put out of operation the ICE, which will not be lubricated properly. Gasoline and oil form the necessary medium that reduces detonation, removes excess debris (waste produced from the combustion of gasoline products) and protects the inside of the engine from wear.
It is important to remember that using the wrong oil can cause damage or clog the engine. Of course, it can be repaired, but in order to prevent possible breakdowns, and to reduce their probability to a minimum, it will be better to study the instruction manual, learn the volume of the two-stroke engine installed on the brushcutter, and use only gasoline and oil, which will fit all the parameters of this model.
It is not uncommon for a manufacturer to give a recommendation (or sometimes even a sticker) indicating a partner company whose gasoline and oil they recommend for their models. Most often the fuel and lubricant recommended by the manufacturer will suit the grass trimmer best.
First of all, you should immediately exclude from the list of actively used lubricants all oils of unknown (garage, basement) origin. Usually it is not easy to dilute such oils because of the unclear basis, composition. Generally, the labels of non-branded manufacturers are not very informative and only provide general information. It is highly discouraged to dilute and dilute oils like AC-10 and ACZp-10. The origin of these lubricants is usually quite obscure, it is better to give preference to trusted brands that are used every day by thousands of people across the country.
A distinctive feature of all oils for two-stroke engines is the fact that manufacturers paint them in a color contrasting with gasoline. The fluid turns out translucent, viscous in consistency, slightly yellowish, but not thick. as a rule, we are talking about three colors. red, green and blue.
Do not forget that the color scheme does not affect the classification in any way (as it is often the case with antifreeze).
Under no circumstances should you use oils from a line not designed for the grass trimmer. It can have an extremely adverse effect on the power unit operation, cause increased fuel consumption, fouling of spark plugs and a number of other problems that will have to be detected and eliminated. It should be noted that if the fact of using oil that is not in the tolerance is established, the seller has every right to remove the unit from the warranty. This means that you will have to replace the failed parts at your own expense, and no exceptions will not help here.
If the fluid you have purchased does not have the declared qualities (for example, it is too thin), you should never mix it with gasoline. The best thing to do is to return such oil back to the store, explaining to the seller the reason for the return.
What kind of gasoline to use
Gasoline for grass trimmer should be chosen unleaded with a tact number of 92 or 95. Practice shows that gasoline AI-80 can cause damage to the device, which is a questionable economy.
The fuel must be fresh, i.e. it must not be stored for more than 60 days after purchase.
Other factors influence the quality of fuel, e.g. the use of special lawnmower lubricant and its dilution in a separate container. It is also recommended to use special canisters designed for storing gasoline.
Two-stroke engines function differently from four-stroke engines: the lubrication of friction surfaces in the crankshaft and other parts of the unit is performed not from the crankcase, but through oil, which has been previously diluted with gasoline. The same general rule applies to two-stroke engines. gasoline is diluted with a certain volume of oil intended for this purpose.
The fuel must be mixed in specific proportions.
Dilute gasoline with a lubricating component should be first in a suitable container: do it immediately in the fuel tank is forbidden. If you ignore this rule, the operation of the motor can be inconsistent, as a result of which the tool will quickly fail. To dilute the fuel mixture, do not use plastic canisters or bottles, because gasoline can dissolve this synthetic material. Order of mixing fuel:
- Pour one liter of gasoline into a container (ideally a metal canister).
- Add half of the required proportion of oil.
- Mix liquids thoroughly, away from open flames.
- Pour the rest of the lubricant into the container and stir the mixture again.
- Pour fuel into the trimmer’s fuel tank.
Wear a respirator and rubber gloves to do the job. You can use a watering can for easy pouring. Do not keep the fuel mix for more than 3 months, it is better to dilute exactly as much fuel as you need for the work you plan to do in the near future. Always choose a quality oil for mixing with petrol; get it from the best quality petrol stations.
Oils to fuel ratios
Calculation of the ratio of ingredients for preparing dressing for grass trimmer should take into account the recommendations on the oil package. The standard ratio is 1:50. Any quality oil for two-stroke motors is allowed to use.
What oil to choose to fill a grass trimmer or types of lubricants
Grass trimmers and lawnmowers are powered by two-stroke engines, which have a simplified design. Rarely, but there are trimmer models with 4-stroke motors that run on pure gasoline. Power units of two-stroke type do not have a compartment for filling the engine oil (oil sump), due to which the weight of the tool and its cost are reduced. If the rotating parts of the engine are not lubricated, they will eventually fail quickly. To prevent this, do not fill the grass trimmer with pure petrol, but with a mixture of petrol and oil. What oil to dilute with gasoline for grass trimmer?
To begin with, let’s remember or find out what types of oils by chemical composition are available:
- Mineral. suitable for low power, air-cooled machines. This is the cheapest type of lubricant for motors
- Semi-synthetics. they are used for equipment that has air and water cooling
- Synthetic. suitable for all types of engines with different types of cooling. They do not require frequent changes, and this type of lubricant is several times more expensive than mineral and semi-synthetic
From the above, it follows that for grass trimmer oil with any composition is suitable. mineral, synthetic and semi-synthetic. Oils with different chemical composition differs in price, so rely on the recommendations of the manufacturer of the tool when buying. The instructions include a recommendation about which types of oil are best to use. If it is a TC-W3 standard, then it is not so important what composition the substance should have. In this case, you can dilute mineral, semi-synthetic and synthetic with gasoline.
This is interesting!The main thing when choosing oil is not to get caught on a fake, since today you can very often meet different types of lubricating compositions for two-stroke engines, which consist mainly of low-quality petroleum products.
Oil for brushcuts how to choose, in what proportions to dilute
Many of you have in the household petrol tools, for example, in a private home can not do without a chainsaw. You know, to prepare wood for the winter, comes in handy at construction and repair, and in general, it is a very necessary tool. If the country house also has a decent-sized plot, then the grass trimmer or lawn mower, which also run on gasoline, is simply necessary to deal with the grass.
Of course, you can also buy electric ones, but not everyone likes to pull a 30-meter extension cord to mow a place overgrown with grass up to his knees. That’s why most people prefer to work with gasoline-powered tools. As you know, you need to add to the gasoline special oil for two-stroke engines. That’s what we’ll talk about, because it’s a very important aspect if you do not add oil and add in the wrong proportions, then your engine will fail very quickly and your way will lie in the service center. To avoid all these troubles, you need to add only quality oil in the right proportions.
RYOBI: How to mix and store 2 stroke fuel
The most popular for chain saws, brush cutters and trimmers are products of famous company STIHL. It comes in two packs of 1 liter and 100ml. For those who work a lot, a liter bottle is enough, and a small bottle is enough for a single sawing. A 1 liter container costs 250 and a 10 ml container costs 60. If you take the larger one, the savings are obvious.
The oil is added to petrol in the ratio of 1 to 50, that is, for example, for 5 liters of petrol you add 100 ml. As you can see, a small bottle is perfect for getting 5 liters of gasoline mixture for your gasoline chainsaw or grass trimmer. On the big bottle on the side there are special marks, by which you can determine how much oil you have poured out of the bottle. If you buy a large 1 liter bottle, buy a 20 ml syringe at the drugstore as well. Very convenient 1 syringe of oil per 1 liter of gasoline.
Experts advise to use brand oil for their equipment, it is ideal because it is designed and tested specifically for STIHL tools. Note that Stihl has its own brands, such as VIKING (popular models of gasoline trimmers). Use Stihl oil for them as well and you won’t have any problems at all.
If you have more gasoline mixture than you can use, it’s best to keep the rest in a metal canister or glass container. Never store the mix in a plastic bottle. Of course, if you use up the leftovers in a couple or three days, you can pour the rest of the mixture into a plastic can, but if the mixture will be stored for a long time, then either a can or a glass container. The thing is that the gasoline mixture corrodes the plastic bottle, microscopic deposits of plastic appear in the mixture and this is very bad for the engine. Keep this in mind if you want your tool to run long and trouble-free.
The second most popular brand of oil is the well-known Hooksvarna. Of course, if I think about it that way, more people use STIHL chain saws, at least all my friends and their friends use them only in their work.
However there are those who cherish Husqvarna tools and I understand them, because I personally do not see much difference between Husqvarna and Stihl, both tools are of very high quality. But I have seen the happy owners of chainsaws Husqvarna say that the saws are super. I have not sawed myself, but I always listen to what people have to say. So, if you have a gasoline tool Husqvarna, then it will be better to use a special brand oil for it. Although, nothing bad will happen if you dilute the gasoline with Stihl. But since the manufacturer recommends you to use only his products, that’s what we do.
You can find liter containers on sale. A black, stylish bottle with the same markings on the side as the Stihl (to know how much oil has been poured out of the bottle). Looks absolutely identical to me. This bottle costs 270, a little more.
Both are quality oils, cost about the same, each is diluted 1:50. So feel free to buy any oil, of course, better to take the oil of the brand that you have the tool then everything will be perfect, just as the manufacturer advises. Have a good time mowing and let your lawn mower work for a long time without failures.
The first start-up and running-in of the lawnmower
The correct first start and the running-in of the mower are very important steps when starting a new lawn mower. On the one hand, they allow you to save a gasoline engine life, which is embodied in the manufacturer, since at this stage there is a lapping of the moving parts and components. On the other hand. the first necessary skills of working with the trimmer are acquired, if we are talking about the first tool in life.
Most drivers know that two-stroke engines run on gasoline and oil. It is therefore recommended to observe the proportions that are specified in the product data sheet.
Of course, some experienced vehicle owners create the proportion by eye. However, each time such a mass will have a different ratio. This will adversely affect the performance of the engine. That’s why you have to read the instructions on the package.
Recommended requirements for the operation of the mixture:
- Do not reduce the amount of oil component when mixing with fuel. stick to the ratio of 1 to 50. This is how much oil? It is necessary to know the exact amount before pouring the mixture into the crankcase. Oil is not a cheap component, so it’s not uncommon to try to save money on it. But it may cause the system to heat up too much. That is why the oil proportions should be observed. Besides, scuffing may occur due to insufficient quantity of this component, which will considerably reduce engine durability.
- Nor should you use copious amounts of oil. If you use too much oil, it is bad for the engine’s performance. It leads to fast engine wear and tear, increased soot deposits.
- The fuel mixture should not be stored for more than 30 days. Otherwise, it loses the necessary properties, and its use will significantly reduce the life of the engine.
- It is required to ensure that there is no dust, dirt in the composition, because it will also have a negative impact on the operation of the motor.
Choice of gasoline brand for trimmers
The longer the journey, the looser the better. If they are not, it won’t be long before the engine is broken. Often unleaded fuel with an octane rating of 92 or 95 is used to fill the gas tank of the grass trimmer.
Gasoline for the fuel mix
Filling the grass trimmer with gasoline AI-80 can cause damage to the device due to its low technical characteristics. Note that the fuel after purchase can be stored for no more than 60 days, and it is better to reduce this period.
Do not use polyethylene canisters for storage, t. к. Static electricity will build up when in contact with the inner walls. Accidental sparking will cause an explosion. Although, there are special plastic canisters marked “flame”.
