Synthetic oil has been around for decades, but myths and misconceptions about its use still persist. As an AMSOIL dealer, I’m here to set the record straight and debunk some of the most common myths about synthetic oil. Let’s separate fact from fiction and help you make an informed decision about your vehicle’s lubrication needs.
Myth 1: Synthetic oil causes leaks in older engines
Fact: Synthetic oil does not cause leaks.
This myth likely originated from experiences with early synthetic oils in the 1970s. Modern synthetic oils, like those produced by AMSOIL, are fully compatible with engine seals and gaskets[1]. If an engine starts leaking after switching to synthetic oil, it’s usually because the superior detergents in synthetic oil have cleaned away sludge that was previously sealing worn components. The oil didn’t cause the leak; it simply revealed an existing problem.
Myth 2: You can’t switch back to conventional oil after using synthetic
Fact: You can switch between synthetic and conventional oil without issues.
There’s no truth to the idea that once you use synthetic oil, you’re committed to it forever. You can safely switch back and forth between synthetic and conventional oil as often as you like[3]. However, given the superior performance of synthetic oils, especially AMSOIL products, you may not want to switch back once you’ve experienced the benefits.
Myth 3: Synthetic oil is too expensive
Fact: Synthetic oil offers excellent value for money.
While it’s true that synthetic oil has a higher upfront cost than conventional oil, it’s important to consider the long-term value. AMSOIL synthetic oils offer extended drain intervals, better engine protection, and improved fuel economy[2]. When you factor in these benefits, synthetic oil often proves to be more cost-effective over time.
Myth 4: Synthetic oil is not suitable for new engines
Fact: Synthetic oil is excellent for both new and old engines.
This myth couldn’t be further from the truth. Many new vehicles actually come from the factory filled with synthetic oil. Synthetic oils, particularly those from AMSOIL, are designed to provide superior protection for engines of all ages[1]. They’re especially beneficial for new engines with advanced technologies like turbochargers and direct injection.
Myth 5: You need to break in your engine with conventional oil before switching to synthetic
Fact: Most new engines can use synthetic oil right from the start.
Unless your vehicle manufacturer specifically states otherwise, it’s perfectly fine to use synthetic oil in a new engine. In fact, the superior lubrication properties of synthetic oil can help protect your engine during the critical break-in period[1].
Myth 6: Synthetic oil doesn’t need to be changed as often as conventional oil
Fact: While synthetic oils can last longer, you should still follow manufacturer recommendations.
It’s true that synthetic oils, especially AMSOIL products, can last longer than conventional oils. However, it’s important to follow your vehicle manufacturer’s recommended oil change intervals unless you’re using an extended-drain synthetic oil like AMSOIL Signature Series, which is guaranteed for up to 25,000 miles or one year[2].
