Undoubtedly, every chainsaw owner knows how important good and high-quality oil is. And, probably, there is no need to say that this is a kind of “life force” of this device for producing full-fledged and effective work. Today there is a huge number of oils and, as they say, there is plenty to choose from.
But, unfortunately, not every owner of this type of electrical equipment knows what oil to use for his iron friend so that the operation of the chainsaw is not only easy, but also productive. Therefore, in this article we will consider the issue regarding the correct choice of the manufacturer of the calm. And also, what it should be in order to help the chainsaw during its immediate activity, and not harm. So let's get started.

Oil for chainsaw chains. What oil should I use to lubricate a chainsaw chain?
Chainsaws are a popular tool for those who have to do countless household chores without the help of others. They can be used for various purposes - preparing firewood, cutting dry branches... But in order for the device to last as long as possible, it is necessary to properly care for it, choosing different compositions well. A special role is played by oil for chainsaw chains, which is selected depending on the operating mechanisms of the tool and its features.
What to consider?
Careful attention should be paid to lubricating the saw chain. First of all, you should choose a special oil that will not harm the oil pump. In addition, this will ensure proper operation of the self-lubrication system. What kind of oil to pour into gasoline for a chainsaw? You can, of course, add other types of oils. The chain also requires proper storage, in other words, immersion in oil, and if it wears out, you shouldn’t try to revive an old chain - it’s easier to change it. Which oil to choose for chainsaw chains so that it is non-hazardous and meets all requirements?
Types and composition
You should choose a specific oil depending on where and how the chainsaw . Mineral compositions are suitable for summer and warm seasons. Very often when selling a chainsaw, the question is asked: “What kind of oil should I use to lubricate the chain?” In other cases, it is better to use synthetic or semi-synthetic oils. It is important to consider which chainsaw oil to pour into a special tank. The Ural chainsaw is considered a descendant of the chainsaw, which oil should be poured into the gearbox. For the purpose of lubrication, used machine chains. If it is necessary to lubricate the chain, you should not use used oils, which will lead to clogging of the fuel system, and then to serious damage to the tool.
Chainsaw chain oil must be thoroughly cleaned so that lubrication can be carried out correctly and accurately. What kind of oil should I pour into the oil compartment of a chainsaw? -. If you use low-quality compounds, there will be no contact between the saw elements and the bar, sparks will appear, and subsequently the moving parts of the saw will wear out.
How to choose?
Each chainsaw has a carburetor two-stroke engine and two tanks: one is filled with gasoline, the other with oil. When choosing a lubricant composition, zoning plays an important role - it should be minimal. Another important indicator is resistance to low temperatures: the oil should not solidify at extreme temperatures, which will ensure the quality of operation of the entire tool.
For lubrication, it is advisable to use adhesive oil for chainsaw chains, which contains special substances due to which the composition adheres well to the chain. High-quality oil will remain on the chain as it rotates, and the chain itself will be more reliable in operation.
Another important indicator of lubricant is thickness: if the composition is liquid, it will be consumed in greater quantities. To avoid harming the environment when using a chainsaw, it is important to use oil - its waste will decompose in the natural environment.
Which chainsaw to choose, since modern manufacturers offer a wide range of options? Among the specialized manufacturers, we can note such brands as Divinol, Bio-Kettenol, Ravenol, VegOil, Mobil, Castrol, Shell. Let's take a closer look at the features of their products.
Divinol
This brand offers high-quality chain lubricant, which has good adhesive and lubricating properties, so that lubrication is carried out efficiently, and chain links and hinges are reliably protected from wear. The optimal combination of viscosity and temperature characteristics ensures that this oil can be used in any season and at any temperature.
Divinol offers different oils for chainsaw chains . What kind of oil needs to be poured into the chainsaw? You can select the oil to fill in. Which one should I use? Zweitaktoel FF attracts attention due to its economical consumption, combination with any fuel, prevention of aging of the fuel mixture and excellent corrosion protection. In addition, this oil can be used at any temperature. Divinol Kettenol and Divinol Kettenol Bio can be used to lubricate chainsaw chains and bars. Using these compounds, you can reliably protect chain links and joints from wear while guaranteeing economical oil consumption. The brand's high-quality organic oils provide excellent lubrication and adhesive properties, making their use not only easy but also environmentally friendly.
Chain oil
In other cases, it is quite possible to replace the chain lubrication oil with any other oil other than working oil. However, there is one more nuance... Users often have a question: “Why is the oil consumption for chain lubrication greater than the fuel mixture? After all, their consumption is related to each other? Here it is worth considering that chainsaw manufacturers calculate the oil consumption for lubricating the chain when filling in their branded oil. And the consumption of any other may differ either less or more.
On many chainsaws, starting from semi-professional ones, it is possible to adjust the oil flow rate for chain lubrication. This is done by adjusting the performance of the oil pump.
If such adjustment is not provided, then the settings come initially from the manufacturer. How to check whether the oil consumption for lubricating the chain on your chainsaw is normal? It is necessary to start the saw, give it gas and bring it to a board, log or other surface that is horizontal. A running chain should scatter oil particles to lubricate the chain and leave a thin, even oil trail.
When to use special chain oil
The use of special oils for chain lubrication will be justified in the following cases:
- You have a new chainsaw under warranty and to preserve it you must use oils recommended by the chainsaw manufacturer. Otherwise, if, for example, the oil pump fails, the repair will not be carried out under warranty. This is especially true for expensive professional chainsaws.
- You respect the environment and prefer not to pollute it again. In this case, oils with the prefix “bio” are suitable.
- When working at critical temperatures.
Which Stihl oil to choose for a chainsaw
Any two-stroke chainsaw engine runs on a mixture of gasoline and oil; accordingly, how long it will last depends on the quality and correct mixture of these components. Also in chainsaws it is necessary to lubricate the bar and chain, and the quality of the lubrication is not the last factor influencing the duration of use of these parts of the chainsaw. In this article we will talk about the oils that Shtil produces and recommends for use not only on chainsaws of its own production.
What lubricant should I use for the trimmer gearbox?
During operation, the mechanical part of the trimmer is loaded by contact forces on the teeth, resistance reactions from adhering grass (sometimes with dirt), dynamic, shock loads due to constantly changing torque. The trimmer gearbox lubricant must fully take these features into account, so the selection of the brand must be strictly individual.
The following factors are taken into account:
- Manufacturer's brand. It is not without reason that each brand focuses on its own made lubricants (we can talk about cheap Chinese products later). This applies to manufacturers such as Husqvarna, Stihl, Huter, Makita, etc. The exception is domestically produced trimmers: for example, Caliber in the user manual does not indicate the brand of lubricant at all...
- Lubricant viscosity. As is known, all lubricating compounds are divided into three groups - high-viscosity (colloidal systems containing various additives), plastic compounds for universal use and solid lubricants that soften during operation.
- Good adhesion to the surface of gearbox parts, as a result of which the lubricant is not squeezed into the gaps or out of the assembly.
- The intensity of lubricant consumption by the gearbox. Here you have to rely on your own experience and recommendations of specialists, since some trimmer manufacturers, relying on the availability of their own service centers, do not give clear recommendations at all regarding the period of operation of the gearbox between two lubrications.
The consumption of a lubricant also depends on the temperature at which it retains its lubricity. When the gearbox is heated to 40°C, it is considered that its operating conditions are satisfactory and there is enough lubrication.
It is believed that there is no universal lubricant for the trimmer gearbox, but this is not entirely true. In fact, a suitable lubricant composition will be one that contains the following components:
- Anti-wear additives that do not contain toxic lead;
- Solid lubricants with the presence of graphite or molybdenum disulfide (the latter is preferable, since the lubricity is completely preserved over a wide range of shaft speeds);
- Only mineral (inorganic!) oils, highly purified.
The mentioned requirements are fully met by lithium greases Gear Grease OREGON or Champion EP-0, domestic compositions Oleo-Mas, Litol -24, or Azmol 158, as well as those recommended by the manufacturer of a specific trimmer model.
Stihl lubricant for two-stroke engines
Stihl engineers develop oils that are optimally suited for all two-stroke engines installed on Stihl chainsaws and trimmers and more. The Stihl line of lubricants for two-stroke engines includes several product options:
- Stihl HP;
- Stihl HP Ultra;
- Stihl HP S
Stihl HP review
Shtil HP is a chainsaw lubricant designed to meet high quality requirements and is intended to lubricate the internal parts of the engine during operation. It is made on a mineral basis and has good combustion performance (has a low level of emissions of harmful substances during combustion).
The original Stihl HP is red and comes in original Stihl packaging.
It comes in several packaging options, the most popular of which is a one-liter bottle with a built-in dispenser. You can also find Stihl HP in canisters of five, ten and fifty-five liters.
The smallest packaging of Stihl HP, which is convenient to use in cases where you need to prepare only one liter of fuel mixture, is a twenty-gram plastic bottle.
The company also produces one hundred gram Stihl HP bottles, which can be used to prepare five liters of fuel mixture.
According to the manufacturer's recommendations, Stihl HP can be used to prepare a mixture for any two-stroke engines.
The shelf life, if stored in a closed container, is 4 years.
Stihl HP Ultra review
Unlike regular Shtil HP oil, HP Ultra is designed for high engine loads during operation and is recommended for use on professional chainsaws. This oil is synthetic. To ensure that consumers do not confuse diluted fuel, it has a green color; accordingly, a ready-made mixture of gasoline with Stihl HP Ultra also has a greenish tint.
There are only two packages of this oil. This is Stihl HP Ultra 100 ml and 1 liter with dispenser.
The cost of Stihl HP Ultra is almost twice the price of Stihl HP and for this reason it is less popular in our country.
The Stihl HP Ultra has a shelf life of four years.
HP Super
Designed for high-performance and four-stroke engines made using 2-MIX technology. The characteristics are slightly worse than those of the HP Ultra, so at the moment the HP Super is not available on the shelves of official Shtil dealers.
Signs of common problems
Knowing the internal structure of the lawn mower and the principle of its operation, you can easily troubleshoot problems with your own hands. Some breakdowns occur most often and are identified as the main ones.
Engine malfunctions should be looked for if the brush cutter does not work or does not even start
It is also worth paying attention to this part of the scythe if you hear unusual noises or feel strong vibration during operation. A clogged air filter can also lead to engine problems. If fuel does not enter the combustion chamber, then the cause should be a clogged fuel filter.
It is also worth looking at it if the tool does not work at low speeds
If fuel does not enter the combustion chamber, then the cause should be a clogged fuel filter. It is also worth looking at it if the tool does not work at low speeds.
No spark. This often happens if fuel floods the spark plug.
The brush bar of the brush cutter vibrates a lot, which makes working with it more difficult.
The gearbox heats up excessively in a short time, which is felt during operation of the scythe.
At low speeds, the line spins weakly, which affects performance.
The starter grid is clogged - the reason for the engine to overheat and stop working. The starter can also fail when the cord breaks when started too hard.
A clogged carburetor may be due to the use of low-quality fuel.
It is also important to pay attention to the carburetor in time if the mixture is leaking
The lawn mower stalls after turning off if the carburetor is not configured correctly.
Malfunction - The knife and reel do not rotate.
Cause - Wear of transmission elements.
The transmission of these lawn mowers consists of a lower gearbox, a shaft and an upper gearbox (cup). Let's take a closer look at them.
Lower gearbox.
The gearbox consists of a housing and a gear pair, which are subject to wear.
This happens due to the lack of lubrication in the gearbox.
Do not neglect this procedure while using the lawn mower.
Lubrication control will extend the life of the gearbox.
There are sets of gears for these gearboxes on sale, but their cost exceeds 60-70% of the cost of the gearbox, and the process of replacing them is labor-intensive; a simple solution would be to replace the gearbox with a new one.
Drive shaft and rod
The transmission of traction from the engine to the gearbox is ensured by a rigid shaft, at the end of which there are splines. Due to lack of lubrication in the gearbox, the splines may wear out. In this situation, only replacing the shaft with a new one will help.
Please note that there are 3 types of shafts (7 splines, 9 splines and “square”). The shaft length, as a rule, on such models is 152mm. Replacement is very simple - dismantle the old shaft and install a new one
Replacement is very simple - dismantle the old shaft and install a new one.
Upper gearbox
The upper gearbox has a clutch cup, which has splines for the shaft.
If they wear out, they will need to be replaced.
The cup can be replaced either separately or the entire upper gearbox.
To remove the cup, you need to remove the locking ring (item 49), catching its “ears” in the holes of the cup (item 48).
Please note that the cup also has shaft options (7 splines, 9 splines and “square”)
Gasoline trimmer clutch
The blade or reel rotates at idle (provided that the carburetor settings are correct)
If such a malfunction occurs, you will need to replace the clutch spring or the clutch assembly.
Clutch replacement:
To replace the clutch, you need to unscrew the upper transmission gearbox. Next, unscrew the spark plug and stop the piston movement with a special stopper. We unscrew the 2 screws securing the clutch (item 57) with washers (item 56), remove the clutch assembly and the washers under it (item 53). We change the spring on the clutch, or install a new one. Don’t forget to install the washers (item 53), then the clutch, and tighten the bolts (item 57) with special engraving washers (item 56).
Proportions for preparing the fuel mixture
Very often people ask the question how much oil per liter of gasoline is considered normal. It is easy to answer, because the instructions for any Shtil chainsaw, as well as on the packaging of the additive, indicate that when using original Shtil products, the proportions of oil and gasoline should be 1:50. This means that for one liter of fuel, you need to add 20 ml of additive.
During the break-in period of a new chainsaw, it is allowed to slightly increase the amount of oil per liter of gasoline. For example, you can dilute one liter, 25 ml of oil, this will reduce the load on the rubbing parts and extend the life of the chainsaw.
Which oil to choose
If you are a regular chainsaw user and do not use it every day for 6-8 hours, and only work in the summer, then you can use a regular Stihl HP to prepare the fuel mixture for your chainsaw. The optimal ratio of price and quality of lubricant has made it popular among millions of users of power tools.
Stihl HP can be used to mix any two-stroke engine, including moped and boat engines.
How to distinguish fake Shtil oil
Criminals do not miss the opportunity to make money by selling counterfeit products from a well-known brand. Stihl oil is no exception. Most often you can find fake Shtil HP, because its sales volumes are the highest of the entire line of Shtil lubricants.
In order to distinguish a fake from the original, the Shtil company released a special brochure, which recorded all the main differences between the original and the fake.
We also invite you to watch a video that shows, using a specific example, what a package of high-quality Shtil oil should look like and how to distinguish a fake.
Types of Lubricants
To care for the components of the mechanism, fats of different consistencies are used:
- Stiff. Such formulations contain various additives and additives.
- Plastic. They are the most versatile option. Most commonly used for gears and helical gears.
- Solid substance. The suspension plate is in original condition.
The special gearbox is a semi-fluid system.
Trimmer oil is popular. “Style”, Thanks to the special composition and components, wear is significantly reduced and corrosion resistance is increased. The main properties of this brand of lubricant are:
- oxidation resistance;
- high penetrating ability;
- resistance to high temperatures;
- high adhesion
“Style” lubricant Suitable for brush cutters and trimmers, as well as for any housing.
Conclusion
We reviewed all the oils in the Stihl line, and found that the most popular lubricant for 2-stroke engines is Stihl HP. It is this that should be used under normal conditions, because in this case you will not have to overpay, and the engine will be reliably protected.
The saw chain, for ordinary users, must be lubricated with BioPlus, since the other options are intended for harsh conditions or work in winter. Also, we figured out that the correct ratio of gasoline to oil is 1:50, but during the break-in period it can be slightly changed and the mixture can be made in a ratio of 1:40, i.e. 25 ml per 1 liter of gasoline. We learned how to distinguish a fake Shtil BioPlus from the original.
