The differences between oils for custom motorcycles

    Let's try to clarify the ideas by providing you with little information on the characteristics of the oils used for custom and Harley motorbikes.
    Engine oils for custom motorcycles, as well as motor vehicles in general, are available in three main categories: mineral oil, semi-synthetic oil and fully synthetic oil. The best choice for your custom motorcycle depends on various factors, including the type of motorcycle, riding conditions, manufacturer specifications and your personal preferences. Here is an overview of the differences between these oils:

    Mineral oil
    It was the most used oil of the 80s and is the most used on not too recent motorcycles.
    This type of oil is mainly derived from crude oil. It is less processed than synthetic oils, making it generally cheaper. Mineral oils offer basic engine protection and are suitable for older or less performance-demanding engines. They tend to degrade more quickly than synthetic oils, so they require more frequent oil changes. They are not ideal for severe driving conditions or extreme temperatures.
    Advantages: It is generally economical and is suitable for older motorcycles or motorcycles that require low viscosity oils. They tend to have good cleaning ability.
    Disadvantages: Tends to degrade more quickly at elevated temperatures and may not offer the same performance and protection as synthetic oil. Not the best choice for high-performance motorcycles.

    Semi Synthetic Oil
    Semi-synthetic oils are a mixture of mineral and synthetic oils. This combination offers better protection than mineral oils, but at a lower price than fully synthetic oils. They are versatile and suitable for a wide range of motorcycles, including most custom bikes. They can withstand more demanding driving conditions than mineral oils.
    Semi-synthetic is a very versatile oil, with a medium-high lifespan and is highly appreciated by motorcyclists for its value for money!
    Advantages: Offers a compromise between performance and cost. It improves performance compared to mineral oil and can offer good protection for your motorcycle.
    Disadvantages: May not be optimal for high performance motorcycles or extreme uses.

    Synthetic oil

    Fully synthetic oils are formulated from synthetic molecules specifically designed to deliver high performance and superior engine protection, high efficiency (when using the right grade), faster cranking time, lower fuel consumption and more.
    They are particularly suitable for high-performance engines and extreme driving conditions. They offer improved thermal stability and oxidation resistance, reducing engine wear and extending oil change intervals. They tend to be more expensive than mineral and semi-synthetic oils.
    Synthetic oil is a mixture of chemical compounds with the aim of obtaining better lubrication and better specific performance and is certainly among the most expensive on the market.

    For the right choice of engine oil, a whole series of factors must be taken into consideration, including: type of motorbike, your riding style and how much you drive the motorbike.
    When in doubt, it is always better to rely on what is reported in the booklet/manual or rely on the expert advice of your trusted mechanic!

    For your Harley Davidson, the choice between these oils will depend on the year and model of the motorcycle. Harley Davidson motorcycles are often equipped with V-twin engines, and some may require specific company or expert mechanic recommendations for oil. Be sure to consult your motorcycle owner's manual or Harley Davidson dealer for specific recommendations on which oil to use.

    In general, many Harley motorcycle owners prefer synthetic oils for their superior performance and protection. However, it is important to follow the manufacturer's recommendations to ensure the proper functioning of your engine.
