You’ve seen the reminder sticker in the corner of your windshield. Maybe you’ve even glanced at it a few times, thinking, I’ll get to it next week. And then next week turns into next month—and before you know it, you’re overdue for an oil change.

We get it. Life gets busy. But when it comes to car maintenance, few things are as simple or as critical as a regular oil change. If you want to keep your car running smoothly here in Denver—where elevation, temperature swings, and stop-and-go traffic all work your engine a little harder than usual—routine oil changes aren’t optional. They’re essential.

So, why do oil changes matter? What makes them especially important for Denver drivers.

What Does Engine Oil Actually Do?

An engine can’t survive without motor oil. It lubricates all the moving parts, helping everything glide rather than grind. Without clean oil, friction builds, heat increases, and your engine starts to wear down—fast.

Engine oil serves a few essential functions:

• It reduces metal-on-metal contact, preventing premature wear.
• It helps dissipate heat generated by your engine.
• It picks up dirt, debris, and combustion byproducts to keep things clean.
• It forms a seal between pistons, rings, and cylinder walls to maintain compression.
• It adds a layer of protection against rust and corrosion.

Over time, oil breaks down and collects contaminants, which is why it needs to be replaced regularly.

How Denver Conditions Affect Your Engine Oil

Here in Denver, we like to say you can experience all four seasons in a single day. That might make for interesting weather—but it also puts unique stress on your engine and its oil.

High Altitude

At higher elevations, the air is thinner. Your engine has to work harder to maintain power, especially on steep inclines or during mountain driving. This extra workload means higher internal temperatures, which can cause oil to break down more quickly.

Big Temperature Swings

Denver’s climate changes rapidly—from freezing mornings to hot afternoons. These temperature swings can affect oil viscosity (how thick or thin it is), especially if you’re not using the right oil for the season or your vehicle.

Stop-and-Go Traffic

Whether you’re stuck on I-25 during rush hour or inching your way through downtown on a Saturday night, stop-and-go traffic puts added strain on your engine. Every time you idle or accelerate, you’re asking your oil to do a little more work.

Dust and Debris

With dry conditions and plenty of roadside construction, Colorado roads often come with extra dust. These particles can work their way into your engine and oil, leading to faster contamination.

How Often Should You Get an Oil Change?

This is one of the most common questions we get—and the answer depends on a few factors, including your vehicle’s make, model, age, and the type of oil you use.

Here’s a general rule of thumb:

• Conventional oil: Every 3,000 to 5,000 miles
• Synthetic oil: Every 7,500 to 10,000 miles

That said, Denver’s driving conditions may mean you need to be a little more proactive—especially if you:

• Frequently drive in heavy traffic
• Make short trips where the engine doesn’t fully warm up
• Regularly drive into the mountains
• Tow trailers or carry heavy loads

Not sure what’s best for your car? Check your owner’s manual—or better yet, ask one of our mechanics. We’re always happy to make recommendations based on how you drive.

What Happens If You Skip an Oil Change?

We hear this one a lot: What’s the worst that could happen if I go a little longer between oil changes?

The truth is, the effects of overdue oil changes might not be obvious right away. But over time, they can take a serious toll on your engine.

Here’s what you’re risking:

• Engine sludge buildup – Old oil thickens and turns into sludge, which clogs your engine and restricts oil flow.
• Overheating – Dirty or low oil can’t cool your engine properly, which can lead to overheating and warped components.
• Increased wear and tear – Without proper lubrication, your engine’s moving parts wear out faster.
• Reduced fuel efficiency – An engine that’s working harder burns more fuel.
• Costly repairs – Ignoring oil changes can lead to serious engine damage, and in some cases, complete engine failure.

In other words, skipping an oil change to save time or money usually ends up costing more of both.

Signs You Might Be Overdue for an Oil Change

Even if you lose track of mileage, your car might be sending you signals. Keep an eye (and ear) out for these signs:

• Dark, dirty oil on the dipstick
• Knocking or ticking noises from the engine
• Oil warning light on your dashboard
• Exhaust smoke that looks darker than usual
• Burning oil smell inside the car
• Poor performance or reduced gas mileage

If you’re experiencing any of these symptoms, it’s time to schedule an oil change as soon as possible.
