A car is a necessity in most places, but it's also a sizeable investment. You want to keep your car functioning optimally for as long as possible. One way to do this is to switch from conventional oils to synthetic oils for your engine. But why make the switch? Here's how synthetic oil helps your car's engine last longer in comparison to conventional engine oil products.


Fully Synthetic Oils Are Better at Lubricating


The most important trait of your chosen motor oil is that it lubricates your engine and prevents it from wearing down faster. Synthetic oil is a great choice because it's designed specifically to lubricate your engine better, which reduces friction and prevents your engine from reaching the end of its lifespan far before its time.


While it's not a feature that enhances your engine's performance, it's also worth mentioning that you don't have to change your synthetic oil as often as you would conventional motor oil. This helps you save time and money, all while keeping your engine moving smoothly.


They're Impacted Less by Fluctuations in Temperature and Other Common Threats


The biggest issue with conventional oils is that they're more easily impacted by a wide range of external conditions that they'll naturally encounter in daily use. Take, for example, temperature fluctuations. Synthetic oils are often a better choice than conventional oils because they're able to maintain their viscosity in the face of temperature fluctuations. This prevents them from experiencing difficulty flowing when the temperatures are much colder out, as well as thinning out when they're faced with significantly higher temperatures than they're used to.


Another example is when oxidation occurs or similar foreign contaminants start to reach the oil. Normally, conventional oil that oxidizes or is introduced to contaminants will break down faster. If you're not quick enough to address this, your engine could face unnecessary wear and tear if you don't change your oil as needed. Synthetic oil, on the other hand, is less prone to breaking down when faced with oxidation and foreign contaminants, ensuring that your engine receives enhanced protection and lasts longer.


Put simply, if you want to protect your engine and keep it running for longer despite common issues the engine is known to face, you want to use synthetic oil rather than conventional oil for your vehicle's engine.


They Serve to Keep Your Engine Cleaner


It's great that synthetic oils are able to resist the effects of various contaminants, but car owners might still be worried about the introduction of contaminants altogether. Changes in their motor oil's composition could lead to clogs and friction that wear down their engine. Fortunately, this is something you don't have to worry about as much with synthetic oil. Synthetic oil is stellar at preventing deposits and keeping the oil in good shape. Sludge and contaminants then become less of an issue for your engine over the long term.


Choosing the right oil for your engine is important for keeping your car in the best possible shape over the next decade or so. Consider using synthetic oil next time for the benefits outlined in this guide.
