Subaru Oil Change Guide: Types of Oil

The variety of types of available motor oil can be overwhelming, but they break down into three major categories: conventional, synthetic, and high-mileage. The next time you come in to Dalton Subaru National City for a Subaru oil change, talk to our team to find out what’s best for your powertrain.

Conventional Oil

Distilling crude oil to make conventional motor oil was, for a long time, the only method of producing oil. This makes it great for lubricating older engine designs, as they were designed with conventional oil in mind. However, the refining process leaves impurities behind that can clog up modern engines.

Synthetic Oil

Distillation can remove impurities, but it leaves behind oil molecules that are uneven and irregular. Synthetic oil, on the other hand, is produced using chemical processes which break crude oil down to its molecules and filter out irregularities, giving you more consistency and better performance at very high and low temperatures.

Synthetic blend oil is another subcategory to keep in mind. It combines synthetic oil and conventional oil, giving more resistance to oxidation.

High-Mileage Oil

When your car crosses around 75,000 miles, it’s a good idea to switch to a high-mileage oil to keep it healthy. These oils feature additives that cause your gaskets and seals to swell, giving you more protection against leaks. Consult our oil change team before using a high-mileage synthetic oil, as they may not seal as well as other options.
