Subaru Synthetic Oil Vs. Conventional Oil – Which One Is Better?

Subaru synthetic oil is better than conventional oil as it offers a variety of benefits. The major drawback with Subaru conventional oil is that you will have to change the oil after every 3000 miles. On the other hand, with the Subaru synthetic oil you can travel at least 5000 miles before you will need to change the oil.

With that said, Subaru synthetic oils are more expensive than conventional oils. But as you’ll need fewer oil changes with synthetic oils, they may be more cost-effective.

Other benefits of Subaru synthetic oil over conventional oil include:

1)   Better Lubrication

Subaru synthetic oil offers better lubrication compared to conventional oil. This is because it is specially manufactured in the lab with various ingredients rather than refined from natural materials only. This leads to reduced friction on your engines.

2)   Cleaner Engine

As oil rotates on your engines, it may leave deposits. This reduces the lifespan of engines and makes them less efficient. However, Subaru synthetic oils are purer compared to Subaru conventional oils. Hence, they leave fewer deposits and help to remove sludge.

3)   Works Better In Extreme Temperatures

Extreme temperatures can negatively affect conventional oils, while synthetic oils function better at higher temperatures.

4)   Long-lasting

As discussed, synthetic oils last longer, while with conventional oils you will need to change oils more frequently during your travel.
