Let’s get into it.

Why Changing Your Oil Matters More Than You Think

Motor oil is the lifeblood of your engine. Inside your engine are hundreds of metal parts moving thousands of times per minute — pistons, bearings, camshafts, valves, and more. Without clean oil:

  • Your engine overheats

  • Metal parts grind against each other

  • Engine wear increases dramatically

  • Fuel efficiency drops

  • Your engine can seize (which costs thousands to repair)

Oil breaks down over time due to heat, friction, and contamination. That means even if you barely drive, oil still goes bad.

DIY Oil Changes Save Money — and Time

A typical oil change at a shop costs:

  • $55–$95 (conventional oil)

  • $75–$150+ (synthetic oil)

Doing it yourself typically costs:

  • $25–$45 total, including oil and filter

You’ll save money on every oil change — and on many cars, the job takes only 20–30 minutes once you’ve done it a few times.

How Often Should You Change Your Oil?

This depends on the type of oil your car uses.

✔ Full Synthetic Oil

Change every 5,000–7,500 miles

✔ Synthetic Blend Oil

Change every 4,000–5,000 miles

✔ Conventional Oil

Change every 3,000 miles

Most modern cars take full synthetic, which lasts longer and protects better.

Driving Conditions That Require More Frequent Oil Changes

You should change your oil earlier if you:

  • Drive mostly short trips

  • Sit in heavy traffic daily

  • Drive in extreme heat (like Southern California summers)

  • Tow or haul heavy loads

  • Track or drive aggressively

If unsure, always check your vehicle’s:

  • Owner’s manual

  • Maintenance schedule

  • Dashboard maintenance messages

Tools & Supplies You Need

(Everything below is beginner-friendly and affordable)

✔ 1. Motor Oil (correct type + amount)

Check your:

  • Oil cap

  • Owner’s manual

  • Google “YEAR MAKE MODEL oil capacity”

✔ 2. Oil Filter

Choose a reputable brand:

  • Mobil 1

  • Bosch

  • K&N

  • Fram Ultra

✔ 3. Oil Filter Wrench or Cap Wrench

✔ 4. Socket Wrench Set

To remove the drain plug (usually 13mm, 14mm, 15mm, or 17mm).

Never rely on a jack alone — always use jack stands.

✔ 6. Oil Drain Pan (at least 6–8 quarts)

✔ 7. Funnel

✔ 8. Gloves + Paper Towels

✔ 9. Floor Mat or Cardboard

Keeps your driveway clean.

Choosing the Right Oil for Your Car

❓ How do you know what oil to buy?

Three things matter:

  1. Viscosity (e.g., 5W-30, 0W-20)

  2. Type (full synthetic recommended)

  3. Brand (Mobil 1, Castrol, Pennzoil, Valvoline — all excellent)

Viscosity Explained

  • The first number (“0W” or “5W”) refers to cold-weather thickness

  • The second number (“20” or “30”) refers to operating temperature thickness

Most modern cars take:

  • 0W-20

  • 5W-20

  • 5W-30

Check your oil cap or manual.

How Many Quarts Do You Need?

Most cars need 4–6 quarts.
Trucks and performance cars may require 7–10 quarts.

#️⃣ STEP-BY-STEP: HOW TO CHANGE YOUR OIL AT HOME

(Complete Beginner Guide — Follow These Steps Exactly)

Step 1: Warm Up the Engine (2–3 Minutes)

You want the oil warm, not hot.

Warm oil:

  • Flows out easier

  • Removes more contaminants

  • Speeds up the drain process

Let the car run for 2–3 minutes, then shut it off.

Step 2: Lift the Car Safely

If using a jack:

  1. Place jack under the correct lift point (check your manual).

  2. Lift the car high enough to fit underneath.

  3. Place jack stands under the car.

  4. Slowly lower the car onto the jack stands.

If using ramps:

  1. Place ramps on level ground.

  2. Drive car up slowly.

  3. Place wheel chocks behind rear tires.

👉 Never get under a car supported by a jack only.

Step 3: Remove the Undertray (If Your Car Has One)

Many modern cars have a plastic shield beneath the engine.

Remove using:

  • Phillips screwdriver

  • 10mm socket

  • Clips

Set it aside.

Step 4: Locate the Drain Plug & Oil Filter

Under the car, look for:

✔ Drain Plug

A single bolt on the oil pan.

✔ Oil Filter

Looks like a small metal can (spin-on filter) or a plastic cap (cartridge filter).

If you’re unsure:

  • Look up images for your exact model

  • Search YouTube “YEAR MAKE MODEL oil change”

Step 5: Drain the Old Oil

  1. Place drain pan under drain plug.

  2. Use socket wrench to loosen the plug counterclockwise.

  3. Remove the plug by hand once loose.

  4. Oil will come out quickly — keep hands clear.

Let the oil drain 5–10 minutes until it’s just dripping.

✔ Pro Tip:

Tilt the pan slightly so oil doesn’t splash.

Step 6: Remove the Old Oil Filter

If you have a spin-on filter:

  1. Use an oil filter wrench to loosen it.

  2. Spin it off by hand.

  3. Be prepared — oil will drip.

If you have a cartridge filter:

  1. Use a cap wrench to remove the filter housing.

  2. Replace the internal filter.

  3. Replace the rubber O-rings.

Very Important:

Make sure the old rubber gasket isn’t stuck to the engine.
If it is, remove it.

A double-gasket will cause catastrophic leaks.

Step 7: Install the New Oil Filter

For spin-on filters:

  1. Apply a thin film of fresh oil to the rubber gasket.

  2. Screw filter on by hand only.

  3. Tighten until snug + ¼ turn.

For cartridge filters:

  1. Insert new O-rings

  2. Insert new filter

  3. Tighten housing to spec (usually 18–25 ft-lbs)

Step 8: Reinstall the Drain Plug

  1. Clean the drain plug threads.

  2. Install a new crush washer (if your car uses one).

  3. Tighten drain plug snugly (don’t overtighten).

Most drain plugs torque to:

  • 25–33 ft-lbs for cars

  • 35–45 ft-lbs for trucks/SUVs

Overtightening can crack the oil pan.

Step 9: Add New Oil

  1. Open the hood.

  2. Remove oil cap.

  3. Insert funnel.

  4. Pour in 80–90% of the listed oil capacity.

  5. Wait 10 seconds, then check dipstick.

  6. Add more as needed.

Oil should be:

  • Above minimum mark

  • Below the full mark

Fill slowly toward the end.

Step 10: Start the Car

  1. Start the engine.

  2. Let it run for 10–15 seconds.

  3. Check under the car for leaks.

  4. Turn car off.

  5. Wait 1 minute.

  6. Re-check oil level and top off if necessary.

Step 11: Reset the Oil Light

Every car has a different procedure. Search:

  • “YEAR MAKE MODEL reset oil light”

Or check under:

  • Settings

  • Vehicle maintenance

  • Service interval

Resetting the light keeps your maintenance schedule accurate.

Step 12: Dispose of Old Oil Responsibly

Do not throw oil away or pour it down drains.

Most stores will take it for free:

  • AutoZone

  • O’Reilly Auto Parts

  • Pep Boys

  • Advance Auto Parts

Just bring:

  • Sealed oil container

  • Old filter

Common Mistakes Beginners Make (Avoid These!)

❌ Putting in the wrong oil type

Always check your manual or oil cap.

❌ Overfilling the engine

Too much oil can damage the engine.

❌ Forgetting the filter gasket

A stuck gasket causes MAJOR oil leaks.

❌ Not tightening the drain plug

Results in a slow leak or worse… the plug falling out while driving.

❌ Tightening the filter too much

Can crack the housing or make removal nearly impossible next time.

Advanced Tips for Faster, Cleaner Oil Changes

These will make you look like you’ve been doing this for years.

✔ Use ramps instead of jacks

Safer and faster.

✔ Wear nitrile gloves

Keeps your hands clean and protected.

✔ Use a Fumoto or ValvoMax drain valve

Turns future oil changes into a 2-minute job with zero tools.

✔ Use an oil extractor

Sucks oil out from the dipstick — no mess under the car.

✔ Pre-fill your oil filter (only for vertical filters)

Reduces dry start.

✔ Keep a dedicated oil-change kit box

  • Funnels

  • Wrenches

  • Drip trays

  • Filters

  • Rags
