Oil Change Guide: When, Why, and How to Book

Everything you need to know about oil changes—from timing intervals to synthetic vs. conventional, and how to book your next service online.

Regular oil changes are the simplest thing you can do to extend your engine's life. Yet many drivers are confused about timing, oil types, and pricing. This guide cuts through the noise.

How Often Should You Change Your Oil?

The old "3,000 mile" rule is outdated for most modern vehicles. Here's what really matters:

Oil Type Interval Best For
Conventional 3,000 - 5,000 miles Older vehicles, budget-conscious
Synthetic Blend 5,000 - 7,500 miles Moderate driving, good value
Full Synthetic 7,500 - 15,000 miles Most modern cars, performance
High-Mileage 5,000 - 7,500 miles Vehicles with 75k+ miles

📋 Check Your Manual

Your vehicle's owner's manual has the manufacturer's recommendation. Modern cars often specify synthetic oil and longer intervals (7,500-10,000 miles). Following these guidelines won't void your warranty.

Oil Change Prices

What you'll pay depends on oil type and location:

Mobile oil change services typically charge $10-30 more for the convenience of coming to you.

Synthetic vs. Conventional Oil

Conventional Oil

Refined from crude oil. Works fine for many vehicles, especially older ones. Requires more frequent changes. More affordable upfront.

Synthetic Oil

Engineered in labs for optimal performance. Better flow in cold weather, more stable in heat, and longer-lasting. Required by many modern engines. Higher upfront cost, but fewer changes needed.

The Verdict

If your car was built in the last 10 years, it probably calls for synthetic. Stick with what the manual says. Switching from conventional to synthetic is fine (and often beneficial), but never switch from synthetic to conventional.

⚠️ Warning Signs You Need an Oil Change

What's Included in an Oil Change?

A standard oil change service typically includes:

  1. Oil drain and replacement – Old oil out, new oil in (4-8 quarts depending on engine)
  2. New oil filter – Critical for filtering contaminants
  3. Fluid check – Brake, transmission, coolant, power steering, windshield washer
  4. Tire pressure check – Often included
  5. Visual inspection – Belts, hoses, air filter

Good shops will show you the old oil and filter, and explain any additional recommendations without pressure.
