The Myth of the 3,000-Mile Oil Change

By Justin Cupler | July 18th, 2018

Vehicle maintenance is a key to ensuring your vehicle runs in top shape for years to come, and an oil change is one of the most important maintenance items. Sadly, there are many misconceptions about oil changes, including how often you should do one. Some people and repair facilities are still in the old school of thought that you need to change your oil every 3,000 miles.

This is not the truth in most cases, and here is way.

Don’t Change Your Oil at 3,000 Miles

Today’s engine and oil are more advanced than ever before, so there is no need to change your oil at 3,000 miles. Engines have tighter tolerances and oil now has more additives to help it last longer, so manufacturers recommend up to 10,000 miles between oil changes.

How can you find out how often your car needs an oil change? Check out the maintenance section of you owner’s manual.

Why Oil Needs Changed

Oil doesn’t simply stop working. Over time, the constant heating and cooling it goes through and the debris it picks up makes it lose its effectiveness. The only way to restore its ability to lubricate, cool, and clean is to replace it with new oil.

Here’s what happens to cause your oil to break down.

Contaminants

Oil flows through the dirtiest parts of your vehicle’s engine, picking up dirt, debris, and gunk along the way. These contaminants can overwhelm the oil over time, causing it to lose its ability to lubricate, clean, and cool. The only way to restore these properties is to change the oil and filter.

Viscosity

The oil’s viscosity is its thick, sticky consistency when new. As oil ages, though, the constant heating it goes through can break this down, as can the raw fuel it takes on. This results in a watery viscosity that doesn’t allow it to lubricate properly. The only way to restore this viscosity is to change the oil.

Detergent Break Down

The oil’s detergents are responsible cleaning the engine’s internal components. With age and heat, these detergents break down, losing their ability to clean. Replacing the oil restores these detergents, renewing the oil’s ability to clean the moving parts inside the engine.
