What Kind of Oil Do I Need?

Conventional? Synthetic? High-Mileage?

Your engine needs oil for proper lubrication. There are so many different weights, types and brands of motor oil that it can be difficult to find the right option for your next oil change. Learn more about the basic types of engine oil and how you can enjoy an affordable, full-service oil change and inspection in El Cajon, California.

Common Motor Oil Types

While all types of oil work to lubricate your engine and avoid buildup and excessive friction, there are four basic types of oil that have distinct pros and cons. Learn more about each of these types and how to find the best one for your vehicle:

  • Conventional
  • Full synthetic
  • Synthetic blend
  • High mileage

Conventional oil is the most common option, particularly for older vehicles. It’s affordable and dependable, but may be more prone to contamination and breakdown than synthetic. Full synthetic is a pure alternative that reduces the amount of sludge and other buildups in your engine. It’s an incredibly efficient lubrication option but is more of an investment than conventional.

Synthetic blend is a great balance between the two, some of the advantages of each. Blended motor oil is more affordable than full synthetic but still performs better than conventional. Finally, high mileage oil is designed for engines with over 75,000 miles.


Most motor oils come with a few additives. Depending on the oil you choose, these can make up between 5% and 30% of the total volume of your oil. Friction modifiers, foam inhibitors, anti-wear agents, antioxidants and other additives are designed to improve the performance of your engine, reduce wear and clean your engine of oil sludge.
