Types of Motorcycle Engine Oil
Choosing the type of motorcycle oil that you require for your motorcycle is probably your first priority. You must figure out which motorcycle oil will be suitable for your bike. If you have no idea, then you can contact the dealer, who can help you in selecting the right type. But, I think you won’t need to talk to anyone when we are here to help you.
There are 3 basic types of motorcycle engine oil – conventional oil, synthetic oil, and semi-synthetic oil.
Conventional oil consists of refined crude oil that includes other additives, such as detergents that are added to neutralize the acids. Another additive that is frequently used in conventional oil is a friction modifier, which improves lubrication for better fuel economy.
Conventional oils are also known as Mineral oils. My professional opinion is that Mineral or Conventional oil is quite a bit cheaper and is used a lot for old motorcycles. However, these are natural oils coming from the ground that also contain some contaminants. But, don’t worry! The process of refining oil is very thorough.
Synthetic oil is a man-made oil, which contains pure crude as an essential additive. Synthetic oils have improved a lot in recent years with modern technologies. Synthetic oils have a lower viscosity, which makes it smooth for engine parts and reduces internal friction.
Synthetic oils provide better efficiency and performance than mineral oils. It’s just that synthetic oils are quite expensive.
You may think we vouched for both oils and since mineral oils are cheaper, then there is no reason for choosing synthetic oil over mineral oil, right?
Well, that’s not true.
I’ll tell you why. As I said, synthetic oils provide better efficiency and performance than mineral oils but are quite expensive. So, mineral oils may not be a better option when synthetic oils provide better fuel economy and have properties that contribute to a longer-lasting engine and longer periods between oil changes.
My professional opinion is, synthetic oils can be expensive but it is a small price to pay for enhanced engine protection and extended engine life.
It is exactly as the name implies. A mixture of mineral and synthetic oil.
Things to Consider Before Buying a Motorcycle Oil
There are certain things that we all must consider before choosing any motorcycle oil:
If you have no idea or any general knowledge of motorcycle engine oils, then it would be better to rely on the opinion of others, specifically professionals or best motorcycle oil reviews. But, you can’t just march into a store with no idea what motorcycle oil to choose and ask someone else to choose it for you.
Let me remind you, you are the owner of your motorcycle. No one knows which motorcycle oil will be perfect for your motorcycle better than you will. So, the only option left is reading an online review, which I believe is a lot better idea than walking into a store. Online reviews will help you understand the advantages and disadvantages of different motorcycle oils. Moreover, since you are exploring the options, there will be no pressure on you to buy any particular one on the spot.
So, overall, I can say buying motorcycle oil from online sites is probably the best option these days, as you can get the best motorcycle oil for your motorcycle at a better value.
You must figure out which motorcycle oil will be suitable for your motorcycle – synthetic, mineral, or semi-synthetic oil?
To check the compatibility, you must examine your motorcycle requirements and decide which one will be the right choice. Remember, if you choose the wrong one, money will not be the only thing you will waste but you will also reduce the life of your motorcycle.
Levels of Viscosity
Viscosity is an important factor to consider while considering a motorcycle oil. According to professionals, viscosity plays a major role in the performance of a motorcycle engine, especially when subjected to high temperatures.
Types of Additives
Checking the additives is a very common and important factor to consider when choosing a motorcycle oil. As we discussed earlier, mineral oil comes with detergent as an additive. And detergent has a property to remove debris and acids from the engine to make sure it is kept clean and works without any trouble. Not just that. It also improves lubrication and cooling.
Price & Efficiency Ratio
Most people see efficiency and cost differently. According to some, cheaper products have less efficiency than expensive ones. But, that’s just an old myth.
While buying motorcycle oil, you must always give priority to efficiency over cost because efficient motorcycle oil will provide the best performance with a lot less cost. And when it starts giving more at a lesser cost, you will discover that the product is providing excellent value for the money.
You have already seen the best examples of engine oil mentioned above. These are the finest engine oils of 2021. They will improve the performance and efficiency of your motorcycle and provide maximum acceleration at the touch of the throttle. All these motorcycle oils have shear viscosity to perform at extreme circumstances and additives that will remove contaminants and acids from the internal engine area and enhance the ability of the engine to work smoothly.
If you are waiting for picking one of these then I won’t do this mistake. It is because all these engine oils are unique and their performance varies with circumstances and type of your motorcycle. So, it should be you to decide which one of these will be suitable for your motorcycle engine. And since you have already learned about motorcycle engine oils, I am sure you won’t have any problem choosing the right one.
