What to Know About Oil Changes

Oil is one of the most important fluids in your car and, in the interest of your engine’s health, changing it is vital. Oil works to lubricate the parts of the engine so they don’t damage one another, helps keep the engine cool, and prevents carbon from building up. As a result, your car should have its oil changed at the manufacturer-suggested mileage or every six months.
If you’re new to cars, the basics of oil changes are relatively simple. First, there are two types of oil: synthetic and conventional.
More often than not, synthetic-blend is used in trucks and SUVs, while premium conventional oil is commonly found in new cars. Common viscosities include 5W-20, 5W-30, and 10W-30, which covers nearly every light-duty vehicle on the road.
Knowing what kind of oil your vehicle takes can be found in your owner’s manual.
While you can change the oil yourself, it may not be the best idea if you’re new to working on vehicles. The process is relatively simple; however you could end up making a mess. On top of that, disposing of the old oil can be difficult.
Dealership service departments have both the equipment and skill to change your car’s oil quickly and correctly. Most service departments will also check your other fluids, fill your tires with air, and inspect your vehicle for problems. As a result, it’s​ incredibly beneficial to have your car serviced at a dealership rather than take on a new do-it-yourself job at home.

Oil Change Basics in San Diego

What is Synthetic Oil?

Full-synthetic oil, synthetic-blend oil, and high-mileage oil all fall under the synthetic category. Synthetic oil is refined, distilled, purified, and broken down into basic molecules. Through those processes, the impurities are removed and the oil can be customized to modern engines. This includes high-tech and high-mileage engines. Synthetic-blend oil is a combination of conventional and synthetic oils and helps to protect engines under heavy loads.

What is Conventional Oil?

Conventional oil is usually the cheapest at local auto stores. Primarily used in engines that see frequent oil changes and have low mileage, it offers little more than the standard three jobs: lubricate, cool, and prevent.
