Both of these oils are semi-synthetic in nature, formulated for 4-stroke motorcycle engines, and have Ester technology.
5000 lubricant is enriched with HC-tech base oils to preserve engines and prolong transmission life. Phosphorus and sulfur concentrations have been augmented for better catalyst operating conditions.
5100 is a Semi-Synthetic Technosynthese lubricant with ester base oil for anti-wear protection. It has properties that promote gear protection and longer engine life due to improved oil film resilience at high temperatures. Excellent gear protection is also provided in this oil by an innovative anti-wear additive bundle.

Compatibility with the Catalytic Converters
The ash created during the burning of zinc and phosphorus compounds, which are anti-wear additives in the lubricant, is liable for impeding the catalytic converter. The larger the concentration of these additives the higher will be the impact on the catalysts working.
Therefore, higher quantities of zinc and phosphorus additives to prevent wear will have a detrimental influence on catalyst performance.
5000 with lower levels of these additives is more suited for use with the Catalyst since it produces less ash than its counterpart (5100). As a result, it is the optimum oil to be used with the catalytic converters.
When oxidized oil interacts with moisture, dirt, and other particles, sludge develops. It is semi-solid (gel-like) and can limit or block oil flow in an engine. Detergents are added and mixed to prevent them from accumulating.
5000 with a reduced figure of detergent may not be as successful at cleansing the engine as its counterpart. As a result, this oil ranks worse in respect of sludge removal.
5100’s key additions are calcium and magnesium, in greater quantities than its competition. As a result, this oil specializes in minimizing sludge formation.
The quantity of lighter molecules in oil determines its volatility at high temperatures. The oil that has a huge number of simple molecules vaporizes quicker and has a lower flash point (vapors ignition point). As a result, it will burn to cause it to run out quicker, and vice versa.
5000 has a decent number of lighter molecules available, which reduces volatility, and it hits its flash point at quite a greater temperature. This shows that it performs well in terms of protection against burning oil.
To guard against oil combustion, the somewhat higher flash point energy trailed the 5100. This is due to its decent concentration of lighter molecules, which causes it to evaporate slowly and achieve its flash point at a higher point.
Both these oils have the same chemical composition instigating them to have their flash point nearly identical to each other.

The metal pieces rub against each other, causing friction and wear. Engine oil contains anti-wear chemicals that produce a lubricating coating over the engine’s moving components to avoid this. This coating avoids direct metal-to-metal contact, which reduces friction and wears.
5000 is less effective at reducing wear than its counterpart because it includes lesser quantities of the major anti-wear ingredients zinc and phosphorus. This places it in 2nd position with regards to engine wear protection.
5100 on the other hand, contains a greater concentration of anti-wear compounds, resulting in a thicker, more durable covering surrounding metal components. This coating will minimize friction more efficiently and preserve the oil from wear.
Kinematic viscosity is a measure of the capacity of oil to spread momentum. An increased kinematic viscosity indicates that momentum may be easily conveyed across the oil’s layers and particles. The viscosity index measures the oil’s capacity to resist variations in kinematic viscosity caused by temperature fluctuations. The greater the viscosity index, the lesser the temperature suggests kinematic viscosity changes and vice versa. The pour point temperature is the temperature below which the liquid cannot flow due to gravity.
5000 has an inferior density at 20° C and kinematic viscosities between 40° and 100° C, suggesting that it is a lesser effective oil in these temperatures. Its viscosity index is otherwise higher than that of its rival due to the smaller influence of temperature change on its kinematic viscosity.
5100 has the highest density at 20° Celsius and kinematic viscosity at 40° and 100° Celsius, indicating that it is the finest oil. However, its viscosity index is lower because temperature variations have less of an influence on its kinematic viscosity.
In respect of pour point, these oils are comparable. They both have the same pour point, which means they both froze at the same temperature.

Oil Change Interval
Many factors, including TBN, influence how frequently you should replace your oil. TBN stands for Total Base Number, and it represents the total quantity of base additives in the oil that may be used to neutralize acids generated during combustion. As these bases are utilized, their concentration declines over time. As a result, a larger concentration of these compounds indicates that the oil may be utilized for a longer amount of time.
5100 has a greater TBN, allowing for a change after a long period. The 5000 with such a lower TBN, on the other hand, may only be utilized for a shorter period.

5000 can be used in street & race bikes, trail bikes, and off-road bikes, all with four-stroke engines, integrated gearboxes or not, wet, or dry clutches, and exhaust gas after-treatment systems such as catalytic converters and air injection in the exhaust pipe. Other uses include motorcycles without catalytic converters, ATVs, and mopeds.
Whereas the 5100 is suitable for the road and racing bikes, trail, off-road, enduro, trials, fitted with 4-stroke engines, integrated gearboxes or not, wet, or dry clutch, engines meeting Euro 2, 3, 4, or 5 emission criteria, fitted with emissions control systems such as chemical converter, air injection into the exhaust pipe. Other uses include street motorcycles lacking emissions controls, scooters, ATVs, and UTVs.
JASO has developed its very own JASO T903 4-stroke bike standard, which is available in three grades: MA, MA1, and MA2.
Both these 5000 and 5100 falls under the category of JASO MA2 oil standards.
JASO MA2 provides the most efficient frictional levels for clutch activation in all triple biking mechanisms: launching, accelerating, and constant speed.
5100 is the most expensive oil since it is the higher version of other oil. On the other hand, 5000 is a general oil that comes at a lower price. 5100 is not highly priced due to its added perks of a higher number of detergents, anti-wear additives, base additives, and better viscosities at higher temperatures, although the chemical base for both these oils is the same (ester).
