Most modern vehicles need an oil and filter change every 5,000-7,500 miles with synthetic oil, or 3,000-5,000 miles with conventional oil — always defer to your owner's manual over generic rules. A DIY change costs $25-$50 in parts (oil + filter) and takes 30-45 minutes; a shop or quick-lube visit runs $50-$100 for conventional and $70-$120 for full synthetic once labor is included.

What you'll need
- Correct oil (viscosity grade and quantity from the owner's manual)
- A matching new oil filter
- Oil filter wrench, socket for the drain plug, new drain plug washer if required
- A drain pan, jack and jack stands (or ramps), funnel, gloves
- A way to recycle the used oil — most auto parts stores accept it free
DIY oil change steps
- Warm the engine briefly (a few minutes of idling) so oil flows more freely, then park on level ground and engage the parking brake.
- Raise and safely support the vehicle with jack stands or ramps — never work under a car held only by a jack.
- Locate the drain plug, place the pan underneath, and remove the plug to drain the old oil fully (5-10 minutes).
- Remove the old oil filter (expect some spillage) and wipe the mounting surface clean; lightly oil the new filter's gasket before installing it hand-tight.
- Reinstall the drain plug (with a new washer if the manufacturer specifies one) to the correct torque — don't overtighten.
- Lower the vehicle, add the correct amount and grade of new oil through the funnel, then check the level with the dipstick.
- Start the engine, let it run 30-60 seconds, check for leaks around the filter and drain plug, then shut off and recheck the level once settled.
How to reset the oil life monitor
Most vehicles need a manual reset after a DIY change or the dash will keep counting down from before. The steps vary by manufacturer — commonly cycling the ignition and holding a trip-reset button, or navigating an infotainment menu. Check your manual; an incorrect reset just means the light comes on early, which isn't harmful, only inconvenient.
| Oil type | DIY parts cost | Shop cost (parts+labor) |
|---|---|---|
| Conventional | $20-$35 | $50-$70 |
| Synthetic blend | $30-$45 | $60-$90 |
| Full synthetic | $40-$60 | $70-$120 |
Overtightening the oil filter or drain plug is one of the most common DIY mistakes — it can strip threads or crush a gasket, leading to a leak. Hand-tight plus a small fraction of a turn with a wrench is usually enough; check the torque spec if unsure.
Common mistakes
- Using the wrong viscosity grade because 'oil is oil'
- Forgetting to reset the oil life monitor, causing confusion about when the next change is really due
- Disposing of used oil improperly instead of recycling it at a parts store or service station
- Skipping the post-change leak check, missing a loose filter or plug before driving off
