There are three main types of 10W-30 engine oil: conventional, synthetic, and blended. Conventional oil is what I started with; it’s affordable and meets basic needs. Synthetic oil, on the other hand, offers superior performance and protection, especially in extreme conditions. I’ve recently switched to synthetic for added peace of mind. Blended oil combines both types and can be a cost-effective choice for some.
