What's the Difference Between Conventional & Synthetic Engine Oil?

Get answers about Subaru conventional and synthetic oil changes

Conventional oil is similar to what the automotive industry has been using since the first internal combustion engines. It's refined primarily from crude oil extracted from the ground and additives are included in the process. Synthetic oil, on the other hand, is engineered right down to the molecular level for superior performance across the range of engine operating temperatures and other variables.

Which is Better for Your Engine - Synthetic or Conventional Oil?

The simple answer is that synthetic oil is better for your engine. Not only does it last longer between oil changes, it flows more easily in cold start up conditions while coating internal engine components better at hot operating temperatures. That means better protection for your engine to help with a longer and more reliable life. Some engines require synthetic oil, so you should check and see if yours is one of them.

Since around 2007, more and more manufactures have begun to engineer their engines to operate with synthetic oil. It may cost a bit more when the time comes to change it, but you can go 5,000 miles or longer between oil changes. Check your owner's manual to see what your specific vehicle requires.

If the owner's manual does say to use synthetic oil, it's important to do so. Not only can the type of oil affect the factory warranty, but you can run into mechanical issues when using the wrong oil. Even if an engine doesn't require synthetic, it's easy to make the change if you wish. There's no cleaning necessary, and upgrading to synthetic oil will take better care of your engine for the long road ahead.
