The team at Mercedes-Benz of Eugene is here to help. Learn the advantages and disadvantages of synthetic oil vs. regular oil, and schedule your appointment in Eugene today!

What is Conventional Oil?

Conventional oil is also known as just “regular” motor oil. This type of motor oil has been used in combustion engines for decades, and this petroleum-based formula is distilled from crude oil mined from the ground. Conventional motor oil is used to lubricate the moving parts of your engine, which reduces friction and heat. While not the most sophisticated formulation, it is a tried-and-true formula that is typically the least expensive option for Roseburg drivers.

What is Synthetic Oil?

Synthetic oil is also petroleum-based, but the formula is more refined and stable. This means that synthetic oils oxidize less easily, break down less quickly, and last long between oil service. Though synthetic oil service are a little more expensive than a regular oil service, you can wait longer between appointments – which saves you money in the long run. Synthetic oils are also:

  • Less viscous at lower temperatures
  • Better at cleaning your engine
  • Better at protecting critical turbocharger parts (when equipped)

What About Full Synthetic Oil vs. Synthetic Blend?

Not only can you choose between synthetic oil vs. regular oil, but you can also choose between full synthetic oil vs. synthetic blend. A synthetic blend combines both synthetic and conventional motor oil to create a longer lasting, but less expensive hybrid formulation. However, it is not as durable as a full synthetic. Be sure to check your owner’s manual for recommendations or contact our service department, because some vehicles require full synthetic for the best results on the Corvallis roads.
