For every motorcycle, oiling the engine is very important for the proper functioning of the engine. We are well aware that when it comes to the performance of the bike, compromising on the quality of engine oil is like decreasing the performance and life of your bike. Engine oil keeps the engine running smoothly by keeping the pipes clean and well lubricated.
Although motorcycle manufacturers recommend a specific type of engine oils, it becomes a bit of challenging task to select the best engine oil for your bike if you are looking for other available brands in the market. Remember, choosing the engine oil well suited for your motorcycle based on its displacement/cc make a significant effect on its performance. In this blog, we have compiled the list of best engine oil for 125 cc, 150 cc, 200 cc and 250 cc bikes.
Before going further, let’s have a quick reading of what are the actual benefits of engine oil for your motorcycle, types of available engine oils and their difference and, bike engine oil grades meaning.
Benefits of engine oil
The basic need of engine oil is to increase the longevity of your motorcycle engine. To prevent wear and tear of engine parts, it is very important to reduce the friction and heating levels between various components. Engine oil maintains lubrication as it flows to all engine parts, which in turn ensures the smooth running of the engine parts.
When the motorcycle engine parts have been working for a long period of time, deposits of carbon are formed. Engine oil basically has two components, one is the base oil that keeps the engine parts well lubricated and the other is additive than cleans any such carbon deposits.
Timely filling and replacing the engine oil reduces your motorcycle’s vibrations, keeps the engine cool and overall, increases the efficiency and performance of your bike by keeping the engine working properly.
Motorcycle engine oils types
Mineral or conventional engine oil
This oil is best suited for commuter motorcycles which operate at lower speeds and normal conditions as it does not have any complex chemical compounds additives. Use of mineral engine oil is not recommended for high-performance bikes. Extracted as crude oil from the ground, mineral oil is further refined and well blended with certain chemical additives.
Full synthetic engine oil
This oil is best recommended for high-performance bikes as it has excellent heat resistance properties and high level of lubrication. 100% or fully synthetic oils do not have any mineral or crude oil, instead, these are made synthetically from scratch and have fully synthetic additives. These oils are known to have higher oxidation resistance, lubrication and pressure resistance. The performance of a bike is further increased as fully synthetic oils reduce the engine drag and prevent building up of sludge. They also have high viscosity and work well in an extremely cold or hot climate. 100% synthetic oils are pretty much costly.
Semi-synthetic or synthetic blend engine oil
Semi-synthetic oils are a blend of mineral oils and synthetic oil with some other additives. This oil delivers the best of both composition and is well recommended for those who ride in low-temperature conditions and want an added level of protection against oxidation. The level of synthetic oil in the semi-synthetic oil can vary, be it 90% synthetic or even 10% synthetic, which decides the cost of the oil. This oil is most popular for the riders who want to extract good performance from their bike without having to pay more for 100% synthetic oil. Before buying semi-synthetic engine oil, remember to check the composition of synthetic oil in the composition.
Motorcycle engine oil grades
You may have often seen engine oil grade labelled as 10W 30 oil or 20W 40 oil. What is the actual meaning of these engine oil grades? It becomes very important to know the engine oil grade or motor oil viscosity rating when it comes to buying the best engine oil for your bike.
Engine oil grade is denoted as XW-XX, where X represents a number and W means weight. The X preceding W represents the viscosity or rate of oil flow at 0-degree Fahrenheit or -17.8 degree celsius. This means the lower the value of X, the higher the resistance to thinning of oil at a lower temperature. For example, 5W-20 engine oil will less thicken than 10W-20 at cold weather.
The digits after W denote the viscosity of engine oil at 100-degree celsius or 212-degree Fahrenheit. This means 5W-20 will thin out more fastly than 10W-20 grade engine oil.
Now, we will discuss about the best engine oil for 125 cc, 150 cc, 200 cc and 250 cc bike.
