My Buying Guide on ’10W40 Fully Synthetic Motorcycle Oil’

As a motorcycle enthusiast, I have learned the importance of using the right oil for my bike. After trying out different types of oils, I have found that 10W40 fully synthetic motorcycle oil is the best choice for my bike’s engine. In this buying guide, I will share with you my personal experience and knowledge about this type of oil.

What is 10W40 fully synthetic motorcycle oil?

Before we dive into the details, let’s first understand what 10W40 fully synthetic motorcycle oil is. This type of oil is specifically designed for motorcycles and is made from man-made chemical compounds instead of natural ingredients like mineral oils. The numbers “10W40” represent the viscosity or thickness of the oil at different temperatures. The “10W” means that the oil has a low viscosity when cold, making it easier to start your bike in colder weather. The “40” indicates that it has a higher viscosity when hot, providing better protection for your engine.

Why choose fully synthetic over conventional or semi-synthetic oils?

Fully synthetic oils are made up of highly refined base oils and additives that provide superior protection and performance for your motorcycle’s engine. They have a more consistent molecular structure compared to conventional or semi-synthetic oils, which means they can withstand extreme temperatures and pressures better. This results in reduced engine wear, longer intervals between oil changes, and improved fuel efficiency.

Benefits of using 10W40 fully synthetic motorcycle oil

1. Better engine protection: Fully synthetic oils have superior lubricity compared to conventional or semi-synthetic oils, which means they provide better protection for your engine’s moving parts. This helps prolong the life of your engine and reduces wear and tear.

2. Improved performance: Due to their consistent molecular structure, fully synthetic oils provide better heat resistance and can flow more smoothly through your engine even at high temperatures. This results in improved performance and smoother operation of your bike.

3. Longer intervals between oil changes: Fully synthetic oils can last longer than conventional or semi-synthetic oils before needing to be changed. This not only saves you time but also money in the long run.

4. Cold weather starting: As mentioned earlier, 10W40 fully synthetic motorcycle oil has a low viscosity when cold, making it easier to start your bike in colder weather conditions.

5. Resistant to oxidation: Fully synthetic oils are less prone to breaking down due to oxidation compared to conventional or semi-synthetic oils. This means they can maintain their effectiveness for longer periods.

Things to consider when buying 10W40 fully synthetic motorcycle oil

1. Brand reputation: It is essential to choose a reputable brand when buying any type of motor oil as quality can vary significantly among brands.

2. Motorcycle specifications: Make sure to check your bike’s manual for its recommended type and grade of motor oil before purchasing.

3. Price: Fully synthetic oils tend to be more expensive than conventional or semi-synthetic ones due to their superior quality. However, consider it as an investment in your bike’s longevity and performance.

4 .Viscosity rating: As mentioned earlier, 10W40 represents the viscosity rating of the oil at different temperatures. Make sure it matches with your bike’s requirements.

5 .Additives: Look for fully synthetic oils with added additives such as detergents, dispersants, antioxidants, etc., as they provide additional benefits like cleaning deposits and preventing corrosion.

In conclusion

After years of using different types of motor oils on my bikes, I have found 10W40 fully synthetic motorcycle oil to be the best option for me in terms of performance and longevity. It may be slightly more expensive than other types of motor oil but considering its benefits; I believe it is worth every penny spent on it.
