Nope, the 3,000-Mile Oil Change Is No More

By Justin Cupler | August 1st, 2018

Maintaining your vehicle is key to keeping it running for years to come, but there is a lot of misinformation surrounding this key part of vehicle ownership. Oil changes are included in this misinformation as there is an old claim that you must change your oil every 3,000 miles. This is no longer the case for many reasons. Let’s look at a few of the reasons the 3,000-mile oil change is no more.

The 3,000-Mile Oil Change is Gone

Years ago when engines and oil were simpler, just about every engine required an oil change every 3,000 miles. Today, with all the advancements in oil and engines, there is a lot of variation in maintenance schedules between vehicles, including changing the engine oil.

What Makes Us Change Engine Oil?

Oil does more than just lubricate the engine’s moving parts. Sure, that is a main part of its job, but it also cleans and keeps things cool. With age, the oil breaks down and can no longer perform these key tasks, and leaving oil in this condition can cause long-term damage to the engine.

Here’s what actually happens to your engine oil when it breaks down.


The engine is one of the dirtiest areas of your car, so imagine what it’s like inside. The oil flushes away gunk and metal shavings to help keep this dirty area as clean as possible. With time, the contaminants can overtake the oil, causing it to lose its ability to clean and lubricate. Left alone, this can cause engine damage. Changing your car’s oil gets rid of this contaminated oil.


Have you ever noticed how thick and sticky new oil is? This is viscosity, and it absorbs heat and keeping the oil stuck to moving parts after the engine is off, limiting dry startups. With age, this viscosity breaks down, and the oil takes on a watery consistency. This prevents the oil from effectively performing these key functions. Changing the oil renews this viscosity.

Detergent Break Down

Detergents and other additives in engine oil help keep things clean. Over time, these detergents break down and lose the ability to do their jobs. The only way to restore this is to change the oil.
