Synthetic oil
Advantages
1. Temperature resilience: Synthetic oils perform exceptionally well in extreme temperatures. They don’t thicken in cold weather nor thin out when it’s hot, providing a stable performance year-round.
2. Longevity: You can clock in more miles between oil changes when using synthetic oils, thanks to their superior formulation.
3. Efficiency: Enhanced lubrication properties reduce friction, thereby increasing fuel efficiency and engine life.
Disadvantages
1. Cost: Synthetic oils are considerably more expensive upfront.
2. Compatibility: Older models might not be well-suited for synthetic oils, which could lead to leaks or other issues.
Mineral Oil
Advantages
1. Affordability: Mineral oils are less expensive, making them an appealing option for those on a budget.
2. Simplicity: They’re straightforward to use and don’t require any special handling or disposal methods.
3. Historical track record: Mineral oils have been around for ages, and their performance is time-tested.
Disadvantages
1. Temperature sensitivity: Unlike synthetics, mineral oils can become thick in cold temperatures and thin in hot conditions.
2. Shorter lifespan: They need to be replaced more frequently, which can negate the cost benefits over time.
So what do the trends say? In the UK it has definitely been towards synthetic oils due to their superior performance, but with many purists still preferring mineral oil, especially for vintage bikes. If you have a new model with a high-performance engine, synthetic is generally the recommended choice, whereas for older models, it’s essential to consult your manufacturer’s guidelines.
