However, unfortunately, this product is generally used in the Harley Davidson motors that require 20W-50 or 15W-50 oils. So, if your bike is not compatible with it, then you would have to look for other options. Install a tuner for Harley 103 and you can watch the oil condition of your HD on your smartphone.

Buying Guide For The Best Oil To Use In Harley Davidson Motorcycles

oil for harley davidson

When researching on the perfect oil for the Harley Davidson models, you will find a plethora of options in the market. Hence, if you sit down somewhere and try to select one among them, then you would feel like you are banging your head against a wall. Remember, find the right one will improve the smooth performance of your HD just like the high-quality rear shock for HD does.

I know this because I, too, have been there in your position. Hence, to help you with it, I have provided some essential pointers, which can help you to purchase the best product in the market.

So, let’s do some digging about these factors together.

  1. Type of Oils

If you have been riding a bike, namely a Harley Davidson, for a prolonged period, then you probably know about the oil types. However, if you don’t, then let me tell you something. Almost all the types of Harley Davidson models typically support three different types of oils. Here is what you need to know about them.

  • Full Synthetic: When talking about the most popular premium oils for Harley Davidson, the full-synthetic products come at the top of any list. Because of being made with various chemical compounds, they are compatible with almost any type of motorbike.

However, due to their overall efficiency, these oils generally come with a high price range. Therefore, if you are running on a low budget, then the full-synthetic oils might not be a good option for you.

  • Mineral Oils: As you probably already know, the mineral oils are one of the oldest types of motorbike oils. Unlike full-synthetic products, they are a lot cheaper and easy-to-get.

Nevertheless, most people generally use them on vintage bikes. Hence, if your bike currently has an age of 15 years or more, then it would be better for you to opt for this engine oil.

  • Semi-Synthetic: Unlike the other two, which I have mentioned above, the semi-synthetic oils exhibit an amalgamation of distilled crude oil and chemical compounds. So, what’s the catch? Because of having both the features of mineral and synthetic oil, semi-synthetic products are a lot more useful than them.

Furthermore, they can also boost the abilities of your bike’s engine by quite a mile. Apart from that, they are quite cheap too. Sounds impressive, right?

  1. Viscosity

Besides knowing about the types of oil, you would also need to have proper information on its viscosity to proceed any further. The term ‘viscosity’ generally implements the idea of the flowing speed of an oil product. If it has a low amount of viscosity, then it would flow a lot faster than usual.

On the other hand, if it is a high viscosity product, then it will, like molasses, not flow that fast at all. So, how would we check the viscosity of an oil product? There is a way to do it.

Most oil products do come with a number rating, like 5W-20. Here, the number 5 denotes the viscosity grade of the oil in a cold engine. Number 20, on the other hand, indicates the oil flow level when the engine is hot and running.

  1. Additives

Does the oil product come with additives? Yes, this is yet another question that you should ask yourself if you want to purchase the best Harley Davidson motor oil in the market. The additives are a type of engine-refreshing component, which keeps your bike’s engine clean by eliminating acid and debris from it.  

Furthermore, they also help to keep the motor clean and fresh by lubricating it properly. Therefore, it’s a no brainer that you should always go for a product that has a high amount of additives in it.

  1. Age

Unlike alcohol, the more an oil product ages, the lesser its overall efficiency would become. Furthermore, if you use the old oil products repetitively on your bike, then it might also damage its engine severely.

Therefore, besides checking out all the factors mentioned above, you should also keep its age in mind. You can determine the age of an engine oil item by checking its manufacturing date. Make sure not to use a product, which has the age of two years or more.  

So, these are a few factors that can help you to purchase the best oil for Harley Davidson in the market.

Final Verdict

Hence, with this list, I hope I have successfully eliminated the question ‘what type of oil for Harley Softail should perfect for my bike?’ from your mind. If you have a higher budget, then you can try out all of these products to find the one that suits your requirements perfectly.

However, if you are running low on cash, then I would suggest you go for the Valvoline product. It is both quite less expensive and highly efficient. Therefore, I think it should be an excellent option for you.
