Various Types of Bike Engine Oils
Mineral Oil
Mineral oil does not include complex chemical products like the ones we’ll discuss below. If you are someone that does not ride their bike a lot, then we suggest using this type of oil. However, if you are in extreme conditions or ride a lot, this type of oil is not the best option for protecting your engine..
Semi-Synthetic Bike Engine Oil
This oil is a mix of chemical and natural products – hence the name. It increases the lifespan of your motorcycle engine and protects it against heat. If you are a rider who loves going on drives every once in a while, this type of oil will suit your needs the most.
Synthetic Bike Engine Oil
Synthetic engine oils usually provide heat resistance and have great lubrication properties. This type of engine oil is recommended if you like to ride your bike a lot or are in an are with extreme temperatures. Riders that do not use their bikes regularly will not see too many additional benefits from this type of oil.
What to Look into a Bike Engine Oil?
Oil Grades
You have to use certain oil grades depending on your bike. These grades can look something like 5W20, 10W40, and more. The number before “W” indicates the consistency of the oil when the engine is cold. However, these numbers do not represent temperature.
The number after “W” shows how well it will settle at a higher temperature. If the number is higher, it means that the oil won’t break down easily. Finally, the “W” itself stands for winter.
Engine Oil Duration
The longevity and amount of engine oil depends on your motorcycle’s model and requirements. Naturally, the price will increase as the liters go up. Keeping extra engine oil with you is always recommended in case you run out.
It’s also important to make sure that you always get the oil changed regularly to keep your engine in good shape. We also recommend that you clean out the oil filter and air filter as part of your bike’s routine maintenance. Doing so will increase its overall life and give you a smoother experience.
Oil Specification
Getting the correct oil for your engine is an absolute must. Some engine oil works better in hot weather, while others perform well in the cold. There are two main oil specifications – American Petroleum Institute (API) and the Japanese Engine Oil Standards Implementation Panel (JASO).
Additives
Good engine oil will have additives in it to make sure that your engine is performing well. These additives help the oil clean the bike’s engine and prevent corrosion. Even though this isn’t essential, having additives can make a huge difference.
FAQs
Is gn4 good for both the engine and transmission side?
It will work on both engine and transmission sides, but we prefer using the Honda HP Trans 80/85W for your transmission for better results.
How often should I change my oil?
While there is no definitive answer to this, the best time to change the oil is around every six months or after every 2,000 miles.
Is 20W40 good for bikes?
20W40 is thicker than the usual oil for bikes, so it won’t flow as well and can even cause clogs in some rare cases. It won’t properly lubricate your engine.
