Here’s Why Your Vehicle Does Not Need an Oil Change Every 3,000 Miles

By Justin Cupler | August 3rd, 2018

Oil is the lifeblood of your vehicle’s engine. And with such importance, it’s no surprise there is a lot of misinformation and excessive worrying about it. One big misconception is that you must change your oil every three months or 3,000 miles, or your car will leave you stranded on the side of the road.

We’re here to dispel this myth and save you some money.

3,000 Miles Is No Longer the Benchmark

Years ago when engines were not as high-tech and oil was just oil, 3,000 miles was a good standard for an oil change. In modern times, though, every engine is different, so each manufacturer recommends a different oil change interval.

While they all vary, they share one thing: 3,000 miles is rarely ever the recommended interval. These days, most automakers recommend changing your vehicle’s engine oil once every 5,000 to 10,000 miles. You can find out exactly what your vehicle’s manufacturer recommends by looking in the maintenance section in your owner’s manual.

The Real Reasons to Change Oil

Oil doesn’t just wear out. There are chemical and physical things that come into play that force you to change your car’s engine oil or risk permanent damage.

Here are the real reasons to change your car’s engine oil.


Going into the depths of your vehicle’s engine is a filthy job, and your engine oil does it happily. The oil takes on metal shavings from the engine and unburned fuel that creeps past through the combustion chamber. Over time, these contaminants can impede the oil’s ability to lubricate and perform its other duties. The only way to restore it is by changing the oil and filter.


New oil has a thick, sticky consistency known as viscosity. It’s this viscosity that allows it to remove heat from the engine and remain stuck to the moving parts after you turn the engine off to help lubricate during startup. Over time, this viscosity breaks down, and the oil takes on more of a watery consistency. With time, this consistency can cause damage to the engine. The only way to combat this is to change the oil.

Detergent Break Down

Oil cleans the inside of the engine too, and it does this using various additives and detergents. Over time, the heat and friction inside the engine breaks down the additives, making the oil lose its ability to wash way gunk from the moving parts. Changing the oil renews these detergents, so the oil can once again clean as it’s supposed to.
