Low temperatures of 40 degrees Fahrenheit or less require Harley-Davidson SAE 10W40 H-D Motorcycle Oil.
Motorcycle manufacturers typically require higher viscosity oils than passenger cars. Motorcycles often ask for grades like 5W-40, 10W-40, 10W-50 and 20W-50. As with cars, always check your vehicle’s owner’s manual to ensure you are using the correct type of oil for your bike. Fully synthetic Castrol POWER1 4T.
Harley Davidson says you can use 20W-50 Synthetic Oil in almost all weather conditions. It is best used in regions where the ambient temperature varies between 60 and 80 degrees Fahrenheit.
The short answer is yes. Since both oils are formulated to perform the same, it is safe for you to use either oil. Some differences between the two oils are viscosity and base oil.
Our Answer: You can safely dump the synthetic oil and go back to regular oil (but read all the way down first). There won’t be any problems. Synthetic and conventional oil can be interchanged without any compatibility problems or mechanical risks.
Yes, you can use. In 10w50, 10 is the viscosity of the oil at low temperature and 50 is the viscosity of the oil at operating temperature. (when the engine is running). 10w50 is thinner than 20w50 at low temperatures.
If you’re looking for a mineral-based oil, we recommend Yamalube All Purpose SAE 10W-40 Oil. Lucas SAE 10W-40 semi-synthetic motorcycle oil is a good semi-synthetic blend, while Red Line 42504 20W-50 fully synthetic motorcycle oil is a good choice for a fully synthetic option.
Answer: For any Harley Twin Cam engine, we strongly recommend using AMSOIL Synthetic 20W-50 in “all three holes” (as they put it) for two main reasons. Update: AMSOIL now offers specific oil for Harley Davidson primary chaincases and transmissions.
A particularly nice feature of AMSOIL 20W-50 synthetic motorcycle oil is that it can be used in the engine, transmission and primary chain case of Harley-Davidson motorcycles.

Between a 10W-30 and a 10W-40, a 10W30 motor oil would run smoother in colder climates, while a 10W40 would be more effective at preventing engine wear in warmer temperatures.
So, if you drive in a warm climate – especially above 32°C (90°F) – or have an engine that runs hotter than others, an oil viscosity of 10W- 40 good way. This higher viscosity oil is rated for hotter temperatures and can handle the extra heat load from the environment.
Higher viscosity oil such as 10W-40 may be useful for older engines that burn or leak oil. We offer Mobil™ 10W-40 high viscosity motor oils for use in vehicles in excess of 75,000 miles and a synthetic blend oil if cost is an issue.
Car oil and motorcycle oil are not interchangeable
Oil in a car is mainly used to lubricate moving parts in the engine. There are different types of products for the other lubrication needs of your vehicle. Motorcycle oil not only lubricates the engine, it also cools the clutch and protects the gearbox.
In short – You should definitely use motorcycle specific oil if your bike recommends it, but in a pinch automotive oil might be fine. Just make sure the weight is correct.
Not all oils are created equal. To avoid damaging your motorcycle’s engine, we advise you to use motorcycle oil for your motorcycle and car oil for your car. As always, please consult your user manual for correct use.
10w40 oil is a popular general purpose oil that has been developed in many different engines. 20w50 (aka 10w30) is another popular general purpose oil used in engines. The differences between 10w40 and 20w50 are small, but they have one thing in common: They are thicker than regular 20w50 oil.
Designed for high mileage vehicles
Mobil 1 High Mileage 10W-40 Motor Oil is recommended by ExxonMobil for use in high mileage vehicles (including those that use conventional oils with less quality †), including: cars. trucks.
10w-40 has an average cold weather viscosity of 10 and a hot weather viscosity of 40. Similar to Viscosity 20 when cold and Viscosity 40 when hot. 10w-40 can perform better than 20w-40 oil.
