Did you know that when Honda released the first GN4 back in 1975, it established the benchmarks for motorcycle oils? The best value for money is provided by this motor oil if you own a light-duty Honda motorcycle.
The Pro Honda GN4 is a mineral oil with a petroleum basis that is designed for light-duty use in 4-stroke scooters, ATVs, and motorcycles. This is not the proper oil for you if you like to race in your Honda. You require the Pro Honda HP4S for that.
The initial motorcycle oil created especially for motorcycles is called ThePro Honda GN4. The mixture includes a special additive package that goes above and beyond what is needed for motorcycles with a shared engine and tranny sump configuration.
The GN4 now offers improved shear resistance, more consistent viscosity, and a cleaner burn thanks to further development.
Your motor will shift smoother right away if you previously used synthetic oil in your vehicle and opt to switch to the Pro Honda GN4. Additionally, it will be much quieter. This is especially true if your Honda’s service manual specifically suggests the GN4.
For high-performance motorcycles, there are once more superior oils. However, if you’re a casual rider and your motorcycle advises using a premium mineral-based oil, you can’t go wrong with the Honda Pro GN4.

Who makes the oil for Honda HP4?
The first entirely synthetic 4-stroke motorcycle oil from Honda, the New Pro Honda HP4S, has been under development for years. Regular petroleum oils like GN4 and synthetic mixes like HP4 are both compatible with HP4S. Before upgrading to HP4S, the crankcases don’t need to be flushed.
- Simply told, it is Pro Honda’s finest four-stroke oil.
- Both conventional petroleum products like GN4 and synthetic mixes like HP4 and HP4S are compatible with HP4S. Customers can transition to HP4S without requiring any special crankcase cleansing, in other words.
- offers superior oxidation resistance and lower friction than standard oils for improved high heat performance.
- All motorcycles, ATVs, scooters, and PWC manufactured in 2006 or later are recommended for usage with HP4S.
- doesn’t include moly
- At low temperatures, especially during startup, it also provides stronger film strength and faster flow to crucial engine sections.
- maximum power since there is less frictional drag.
What distinguishes 10W30 oil from 10W40 oil?
Multigrade oils, such as 10W-40 and 10W-30, combine the characteristics of two different classes of oil. They are sometimes referred to as “multi weight oils.”
Low Temperature Viscosity
The oil’s viscosity at a low temperature is indicated by the first number. Anything below 0oC is often regarded as low temperature (32oF).
A “10W rating” (thus the “W” affixed to it) is an SAE grade for winter use for both 10W-30 and 10W-40 oils. At lower temperatures, these oils behave similarly to an SAE 10W single grade oil.
When starting a car while the engine is still cold and needs quick lubrication, this value is especially crucial. The oil is thinner and more viscous the lower the number.
High Temperature Viscosity
The viscosity of the oil at 100 oC is indicated by the second digit (after the “W”) (212oF). This is frequently taken to be the operating temperature of the engine.
More viscous or thicker the oil is at higher temperatures, the higher the number.
Accordingly, 10W30 engine oil has the viscosity of an SAE 30 single grade oil at 100 oC, whereas 10W40 oil has the viscosity of an SAE 40 oil.
Because 10W40 oil has a higher viscosity than 10W30, it retains more thickness as the temperature increases.
In that situation, 10W-40 motor oil would theoretically offer superior defense against contact between engine wear and higher temperatures.
Next, let’s compare the performance and application of these multi-viscosity oils.
What kind of motor oil is best?
We advise Yamalube All Purpose SAE 10W-40 Oil if you’re seeking for an oil with a mineral base. The Red Line 42504 20W-50 Fully Synthetic Motorcycle Oil is a respectable alternative for a fully synthetic motorcycle oil, while the Lucas SAE 10W-40 Semi-Synthetic Motorcycle Oil is a solid semi-synthetic blend.
Is synthetic oil recommended for my motorcycle?
Although synthetic oil rarely causes harm, this does not mean that everyone should use it.
Back then, many erroneously believed that synth oil may be too slick and cause “bearing skate.” This fallacy has already been debunked numerous times. There are now two main issues with utilizing synthetic oil. The first is that because synth oil molecules are smaller, they can more readily travel through gaps in gaskets, seals, and fissures. That could indicate that a leak could develop that wasn’t happening with conventional oil. The leak isn’t caused by the synthetic oil; instead, it just locates an escape route that may already be present but wasn’t previously recognized as a leak. It discovers leaks rather than creating them.
Cost is the second negative aspect. Comparatively speaking to conventional or synthetic blends, synthetic oil is quite pricey. It might not be the right stuff for you if you change your oil depending on time rather than miles. On the other hand, if you are putting down a lot of kilometers, you can burn through oil so quickly that the price could be exorbitant.
But as you’ve probably already realized, synthetics have some advantages that conventional oils don’t always offer. In comparison to engines operating on conventional oils, which may use lower-quality additives, synthetic oils frequently feature premium additive packages, which means they frequently aid an engine withstand wear, oxidation, and maintain superior lubrication. In terms of temperature performance, synthetics definitely excel over conventional oils. They can tolerate heat damage at temperatures higher than what regular oil can. Although all oil molecules eventually shorten and condense forming deposits that resemble varnish, synthetics frequently last longer than conventional oils. Because air-cooled machines experience significantly wider temperature variations than their liquid-cooled counterparts, this can be a factor to take into account.
The term “synthetic blend” refers to a combination of synthetic and conventional oils. The blend is not just a 50/50 combination, and the individual additions vary since some elements of the additive packages for synthetic and conventional oils are incompatible. It’s crucial to keep in mind that the additive package plays a major role in the level of protection an oil provides.
“Crude oil is the source of both synthetic and conventional oil. Simply said, synthetics are improved upon, according to Andy.
Another significant point to be aware of is the fact that some motorcycles only allow the use of synthetic fluid. Use synthetic if your bike is one of those, especially if you want to prevent engine wear and maintain your warranty.
Your clutch may slip if you use synthetic oil.
IDRIS PERFORMS
My Honda VFR750 recently had its oil changed, and now the clutch is beginning to slip. Do you have any idea what this could be considering that the bike only has 10,000 kilometers on it?
OUR GURU CONCLUDES:
Most likely explanation: the bike’s engine has too much oil in it right now. Have you tested the level after running the engine while it was cold? Have you used the recommended approval rating, bike-specific, proper grade of oil? Can inexpensive automobile oil purchased from side streets vendors contain additional additives and be recovered oil? Have you switched to fully synthetic oil from semi- or conventionally synthetic oil? Fully synthetic oil’s superior lubricating properties will induce clutch slip when added to a bike with mileage. Try leaving the bike overnight and riding about 30 easy miles the next day if the level, oil grade, and rating are all satisfactory. This is due to the fact that fresh oil poured into the engine might saturate the clutch plates, which can then be cleared by spinning the plates. What about the clutch adjustment? If none of the aforementioned remedies work, the clutch may need to be repaired or it could just be coincidence.
Can you use synthetic oil with a wet clutch?
Use of a lubricant designed especially for wet clutches, such as AMSOIL synthetic motorcycle and dirt bike lubricants, is essential. They don’t have any additives for severe pressure or friction modifiers.

What would happen if I used 10W40 rather than 10W30?
Although the temperature outside doesn’t contribute to the heat your engine produces while running, it does affect oil viscosity. This is why choosing the right oil for your area is crucial. A 10W-30 motor oil would perform better in colder climates than a 10W-40, and a 10W-40 would be better at reducing engine wear and tear in warmer climates.
