THE DIFFERENCE BETWEEN 2-STROKE LUBRICANT OIL AND 4-STROKE LUBRICANT OIL
What is the difference between 2-stroke (2T) and 4-stroke (4T) motorbike lubricants?
Question: What is the difference between 2-stroke (2T) and 4-stroke (4T) motorbike lubricants? Is it harmful to the car if you use the wrong type of oil?
Answer: 2T and 4T engines are different in structure and lubrication type, so they need two completely different types of lubricants. 2T lubricant is mixed with gasoline in an appropriate ratio and enters the combustion chamber to lubricate the cylinder, piston, and piston rings, so it is burned with the fuel. It is an all-consuming type of lubrication, so the oil needs to be constantly replenished. 2T lubricant oil needs to be liquid to easily mix with gasoline (so 2T oil contains solvents). 2T oil must also burn cleanly to create less residue that can dirty pistons, pistons, piston rings and clog pipes. exhaust gas (tailpipe), so the additives used for 2T oil are also different from 4T oil. If you use 2T oil for a 4T vehicle, the engine will heat up, wear more and the oil seals may be damaged because of the solvent. On the contrary, if you use 4T oil for a 2T vehicle, the engine will have a lot of sludge, leading to wear and severe damage to the engine in a short time.

Because lubricants contain detergent and dispersant additives. They are responsible for cleaning the engine and keeping dirt suspended in the oil, preventing them from settling on machine parts. During use, the oil will gradually age and denature, so after a certain period of time it is necessary to change the oil. – If you save money, just adding new oil to the old oil you are using will not ensure the properties of the oil and will not effectively protect machinery and engines. – Must use the correct type of oil and follow the instructions. written on the packaging. – To choose the right type of oil suitable for motorbikes and cars, it is essential that the user must see what type of oil is suitable for that engine and what viscosity it is. Normally, for new vehicles, you should choose thin multi-grade oil (10W40 or 15W40), for engines that have been used for a long time, you should choose multi-grade thick oil (20W50 or 15W50). For cars, usually you should choose multi-grade thin oil (10W40 or 5W40). Source: 24h Business Newspaper

Without lubricant, no engine can operate, regardless of whether it is a car engine or a machine. That is why lubricant oil is considered an indispensable precious material in today’s society. Currently. However, most of us often rely on the information provided by the seller and rarely bother to learn the basic parameters of this material, so it is difficult to avoid using it incorrectly. And to overcome this situation, let’s refer to the following useful information:

*Lubricants and basic parameters.
We all know that there are many factors and criteria to evaluate a good lubricant, but the most important is still viscosity. Regarding viscosity, manufacturers have agreed on the following conventions:
Normally on car oil caps we often see symbols such as 10w40, 15w60,… and their meanings are simply explained as follows:
-Lubricants with the letter W: are called multi-grade lubricants, these are lubricants that can be used in all seasons, including winter, and especially can operate at many different temperatures.
-Other types of lubricants have other symbols such as: c, s, v… v… then they are called single-grade lubricants, only used at a certain temperature, and obviously the lubricants have different grades. The larger the letter, the better.

So what does the number before the letter W represent?
That is the cold temperature at which car oil can still operate in winter. This number is calculated as follows:
For example: 10 W, first we will use the number 30 as the default common number, subtract this front number we have 20, then take its opposite number -20 we have the heat number the temperature at which car oil can operate in winter.
Therefore, the higher the negative level of a certain type of car oil, the better, but that is when used abroad, in countries with snow and in winter with low temperatures. In Vietnam, most of the numbers are limited to a minimum of 15w-20w because the winter in Vietnam is not very cold. On the other hand, these types of lubricants are quite cheap abroad, so importing them to Vietnam brings the best results. , their price is mid-range so they are used quite widely.

What types of engines are single-grade lubricants commonly used for?
With outstanding features and unique properties, this oil is often used in 2-stroke engines or industrial machines.

For many people, the important thing after buying a motorbike is taking care of it. Especially for scooters, changing the vehicle’s oil is an extremely necessary thing. Lubricants greatly affect the performance and longevity of the engine.

In case the user does not have much experience in changing the oil for scooters, they can consult with those who have been riding scooters, go to a motorbike shop and ask  to learn more. Below Here are some questions about changing scooter oil.

1.Why do we need to change the oil for scooters?

During the process of using the vehicle, the lubricant will be contaminated with road dust, sand, and additives, and the vehicle engine will no longer operate smoothly. Therefore, we must change the scooter’s oil after a certain period of time. These periods of time are called oil change intervals.

2. When to change the oil?

The time to change the vehicle’s oil depends on many factors, the most important of which are distance traveled and time, in addition it also depends on external conditions: weather, climate… Usually manufacturers Motorbike will give advice to its customers based on the technical specifications and characteristics of each vehicle model. Manufacturers advise that you should change the oil for old scooters and motorbikes after traveling about 1,000-1,500km, but actually, the oil change cycle for each type of vehicle is different and you should refer to added right in the vehicle owner’s manual. You can refer to motorcycle forums to understand the pros and cons of each type of vehicle and from there have appropriate options to change the oil for your vehicle.

3. Oil change process

Before changing the scooter’s oil, you need to remove all the old oil, then tilt the scooter to let the old oil drain out and then use a steam hose to blow the remaining oil out.

A scooter engine is hotter than a manual vehicle engine because it is covered. In addition, the continuously variable belt drive system makes the engine always have to operate at full capacity, so lubricants for scooters not only satisfy not only meets the need for engine lubrication but also must have higher heat resistance than manual cars. In particular, you need to pay attention to the amount of oil when changing because if you change too much it will make the engine hot and the car will be heavy, if too little it will not be enough to lubricate the engine.

When buying oil, you must carefully read the information on the bottle to ensure it is suitable for your vehicle. In addition, you need to carefully check the packaging and labels. The new lubricant bottle will have a seal membrane to seal the bottle mouth and the plastic layer above. This is an important point to ensure the quality of the lubricant bottle.

After changing the oil, you need to tilt the car to both sides to ensure the oil flows evenly in the car, then step on the starter lever to send the oil to the engines, followed by starting the car engine for a few minutes before driving.

4. Choose the right oil for your car?

Lubricants for scooters have two important parameters: API performance level and SAE viscosity level. When buying lubricant, you need to pay attention to these two parameters to check whether it is suitable for the type of vehicle you are using or not?

On the ViteX scooter lubricant market, you can currently buy it at authorized distributors and stores to ensure the best performance of your scooter engine.

When should you change car oil? And what type of car oil to choose, what is the price and effectiveness? Let’s learn more with VITEX through the article below.

In addition to car parts, lubricants are one of the important factors. In the current Vietnamese lubricant market for cars, there are many types sold with many different brands and lubricant standards. Depending on usage status, longevity and engine type, buyers need to have basic knowledge to choose the appropriate type of car lubricant. Here are some issues to keep in mind when changing the oil for your “box truck”:

1. Lubricant index

Automobile oil indexes are one of the important information about lubricant standards that buyers need to pay attention to. These indices can be found on the product label, including the viscosity index according to the Society of Automotive Engineers (SAE) and the performance index according to the Petroleum Institute. American Petroleum Institute (API – American Petroleum Institute).

The SAE index is often denoted as SAE 0W-40 or SAE 20W-50… In which ‘W’ stands for multi-grade oil, with satisfactory viscosity at many different temperature conditions, used in all applications. seasons of the year, unlike single-grade oils that only respond to a certain temperature. The number before ‘W’ indicates the temperature at which the oil helps the engine start well (calculated from negative temperatures by subtracting that number from 30) and the number after ‘W’ indicates the viscosity of the oil at 100 degrees Celsius (the higher the value, the greater the viscosity), usually from 30 to 50. Depending on the conditions and route the vehicle is traveling, choose an oil with appropriate parameters. For example, if a car travels a lot on the road, it should choose a large oil viscosity parameter, but if it travels a lot in the inner city, an oil with a small oil parameter will be more suitable. Single-grade oils will be denoted as SAE 30, SAE 40… suitable for use in agricultural and industrial machines.

The API index is often denoted starting with the letter ‘S’ or ‘C’, in which ‘S’ is the oil used for gasoline engines and ‘C’ is for diesel engines, for example SA, SB , SC, CA, CB, CC… The newest levels currently according to API are SN and CI. The letters after ‘S’ or ‘C’ are used to distinguish levels and are ranked alphabetically, in which the larger the alphabet, the better. To know which type of oil is suitable for the characteristics of the car engine you are using, it is best to listen to recommendations from experts, ask the company’s technicians for advice as well as choose reputable lubricant brands. Or find out more information from car parts trading sites…

2. Conventional lubricants and synthetic lubricants

Although current automotive lubricants all meet API and SAE standards, conventional oils will have fewer additives so the price is much cheaper than synthetic oils, suitable for those who need them. Frequent oil changes and low mileage.

On the contrary, although the price of synthetic lubricants and oils is three times more expensive than conventional car oils, this type of oil brings many benefits to the engine because it helps lubricate machine parts with small openings. This helps extend the usage time many times compared to conventional oils and ensures the best dynamic protection for the engine. Instead of saving money to buy synthetic lubricants, think about the amount of money you have to spend on repairs, which will be many times higher once the engine breaks down because of using the wrong type of lubricant.

3. Change car oil periodically

Automobile lubricants during use will degrade due to the impact of heat, impurities and oil additives will be consumed, gradually losing the ability to lubricate and protect the engine. Therefore, it is necessary to change the oil after a certain period of use recommended by the vehicle manufacturer or according to the number of kilometers the vehicle has run. Most often change car oil every 3 months or 5,000 – 10,000 km or combined with general car maintenance. However, current car lubricant standards have been greatly improved in quality, so they can help cars travel nearly 12,000 km after each new change unless the engine operates in harsh conditions.

Choosing the right type of lubricant will help protect the engine more effectively, enhancing corrosion resistance for metal and alloy surfaces. In addition, lubricants also have the effect of cooling and cleaning the internal parts of the engine, retaining harmful residues on the machine, contributing to improving the longevity and operating efficiency of the car.

Hopefully the above information will help you gain basic knowledge to choose the most suitable lubricant for your car. In addition, you can also find more information about lubricant standards of different brands on forums or recommendations from manufacturers, garages or maintenance companies…

As one of the most popular means of transportation in our country today, scooters may no longer be unfamiliar to many people. However, like other vehicles, users often make the same mistake: they rarely pay attention to choosing lubricants for their vehicles. Because of this, our car “disintegrates” faster than ever after being driven for a while. Only by choosing and changing car oil regularly can we maintain the engines inside our car, not only making them wear less but also moving more smoothly as desired.

*Lubricant – Increases the life of our car engine.

If we want the engine to function well, our car must be equipped with good lubricants. Without this valuable material, our car would not be able to operate well. The engine’s metal surface rubs hard and quickly, generating a large amount of heat and soot. Without lubricating oil to act as a barrier and heat sink, our cars will quickly catch fire and be damaged.

Keeping your car’s engine smooth, as well as the time you should change the oil, helps your car maintain its desired lifespan.

So when should we change the car’s oil?

*The car oil change stage includes the following basic stages

– Change the car’s oil after traveling 300 km.

– Change the car’s oil after traveling 700 km.

– Change the car’s oil after traveling 1500 km.

And after the first three stages, every 2000km-3000km we should change the car’s oil once to help the car operate better.

*Should I choose genuine car oil or foreign car oil?

Normally, during the first two oil changes, we can choose the car’s genuine oil, but in the following times we should choose external oil because they are much better than genuine car oil.

*What are some of the most popular types of lubricants today?

– Topping the voting are: Vitex, Motul, Castrol, Shell, Mobi.

In terms of appearance, motorbikes are completely different from cars. This difference is not simply in appearance, four wheels or two wheels, but is a difference in operating mode, operating structure…

And so manufacturers of motorbike lubricants are completely different from car lubricants. It’s not necessarily true that high-quality lubricants for cars have better performance than motorbikes.

Differences in operating mode

A 1-cylinder motorbike or motorbike engine with a capacity of 150cc can produce 15 horsepower and a rotation speed of up to 7500 rpm. Meanwhile, a 1500cc family car engine has a capacity of about 100 horsepower and reaches 5000 rpm. Thus, the car cylinder capacity is 10 times higher but the generated power is only 6.66 times higher. This shows that motorbike engines work harder than cars. Therefore, the quality of motorbike oil is completely different, and the sliding durability is higher than that of car oil.

Differences in engine protection

For four-stroke motorcycles, the gearbox and clutch are mounted in the same box as the engine. Therefore, motorcycle lubricants are used to protect and lubricate the engine, gearbox and clutch. This is the three-in-one function of motorcycle lubricants. Therefore, they must ensure features to lubricate the engine well, protect the gearbox against pressure and wear, and have enough friction to avoid clutch slipping. Meanwhile, car oil only needs to lubricate and protect the engine.

For engine and transmission protection, when choosing lubricants, we can look at the data listed on the product packaging of lubricant manufacturing companies.
