Changing Car Oil at Home: A DIY Guide

Changing your car oil regularly is one of the most important things you can do to maintain your vehicle and keep it running smoothly for years to come. Not only does an oil change help extend the life of your engine, it also enhances performance and fuel efficiency.

While you can always take your car to a mechanic for an oil change, doing it yourself at home can save you money and it’s very rewarding. With some basic tools and supplies, changing your oil is an easy DIY project for both novice and experienced car owners.

This comprehensive guide will walk you through everything you need to know to change your car oil safely and properly in your own garage.

Understanding Why Oil Changes Are Necessary

Before learning how to change your oil, it helps to understand why oil changes are so critical in the first place.

What Exactly Does Motor Oil Do?

Engine oil serves several important functions:

• Lubrication – Oil coats all the moving components in the engine, preventing metal-on-metal contact friction and wear. This allows parts like pistons, valves, and bearings to move smoothly.
• Cooling – Oil carries damaging heat away from the combustion chamber and other hot spots to be cooled. This heat protection preserves the engine.
• Cleansing – Oil circulates through the engine, collecting debris and contaminants. The oil filter then removes these harmful particles from the oil.

If you don’t change your oil regularly over time, it becomes dirty and less effective at these jobs. This puts your engine at risk.

What Happens If You Don’t Change The Oil Enough?

Infrequent oil changes can lead to:

• Build up of sludge that clogs small passageways
• Increased friction and engine wear
• Overheating
• Higher emissions and reduced fuel economy

All of these negatively impact engine operation and can lead to serious repairs or even complete engine failure down the road. That’s why changing car oil at regular intervals is so critical.

How Often Should You Change Your Car’s Oil?

Here are some general oil change frequency guidelines:

• Conventional oil – Change every 3,000-5,000 miles or 3-6 months
• Synthetic blend oil – Change every 7,500-10,000 miles or 6-12 months
• Full synthetic oil – Change every 10,000-15,000 miles or 12+ months

Check your owner’s manual for the interval recommended for your vehicle based on your normal driving habits and climate. Changing it more often than needed is wasteful, while changing it less often puts your engine at risk.

Preparing for an Oil Change

Before you get your hands dirty, take a few minutes to set up your workspace and get all the necessary materials together. Rushing into an oil change unprepared can cause mistakes, so walk through this prep work carefully.

Choose Your Workspace

Pick a workspace that will allow you to safely get under your vehicle. Avoid steeply inclined driveways or uneven ground. Your vehicle should be as level as possible during the oil change process.

Ideally, use car ramps to gain access underneath your vehicle. Ramps provide an affordable, low-profile way to lift your vehicle. Place the ramps at the manufacturer’s recommended points underneath the front wheels.

If you don’t have ramps, use a floor jack with jack stands instead. Place the jack at the vehicle’s recommended lift points to raise it. Secure it on jack stands for safety.

Gather Tools and Materials

An oil change requires a few basic tools and materials. Here’s what you’ll need:

Essential Tools

• Adjustable wrench
• Oil filter wrench
• Funnel
• Rags
• Work gloves
• Eye protection
• Optional – floor jack and jack stands

Necessary Materials

• Motor oil (check your manual for the right viscosity)
• New oil filter
• Drain pan to collect used oil
• Shop towels or rags

Ensure you have all these items on hand before raising the vehicle or beginning any work. Place the drain pan underneath the oil drain plug location to containing dripping oil when you first unscrew the plug.

Step-By-Step Oil Change Process

With your workspace set up and materials gathered, you’re ready to tackle the oil change process itself. Follow these steps in order:

Drain the Old Motor Oil

Draining the old oil is the first step of any oil change:

1. Raise your vehicle using ramps or a floor jack until there is enough clearance to access the oil drain plug underneath the engine. Make sure you raise the vehicle according to manufacturer guidance.
   WARNING: Always lift your vehicle on level ground and secure it properly on jack stands for safety if needed before going underneath.
2. Position your oil drain pan underneath the vehicle’s oil drain plug. Typically near the back of the oil pan or lowest point on the engine.
   TIP: Place a funnel in the drain pan to help guide the stream of old oil neatly into the container without splashing.
3. Put on gloves and eye protection to protect yourself from oil splatter, burns or debris.
4. Use your adjustable wrench or the correct size socket wrench to slowly loosen the oil drain plug, turning it counter-clockwise. Applying penetrating oil first can help loosen a stuck plug.
   WARNING: Very hot oil will begin to drain immediately once the plug is loosened. Avoid burns by keeping skin clear while initially unscrewing the plug.
5. Once the plug is completely off, allow all the old oil to fully drain out. This may take 10-30 minutes depending on temperature. Inspect the color and quality of the oil as it drains too – this can indicate engine wear or issues.
6. After the oil has fully drained, carefully reinstall the drain plug. Make sure its sealing washer is in place then tighten it securely.
   CAUTION: Don’t over tighten or you may damage the threads in the oil pan.

With the drain complete, it’s time to tackle the next critical step – replacing the oil filter.

Change the Oil Filter

The oil filter pulls contaminants and particles out of the circulating oil. Like car oil, filters need regular changing. Here’s how:

1. Locate the sealed metal oil filter housing attached to the engine. Ensure your drain pan is still underneath since some oil will spill out when you open the housing.
2. Use your oil filter wrench to grip and turn the filter counter clockwise. Applying light force, unscrew it completely using caution as pressurized hot oil may initially blow out.
   TIP: Stuck filters can often be loosened by pounding the handle of a screwdriver through the top to break the seal.
3. Pull out the old oil filter and discard it properly in your oil recycling container. Avoid spilling residual oil as you handle the filter.
4. Use a clean lint-free rag to wipe any remaining oil, gasket seal material or debris from the filter mounting base.
5. Apply a thin coat of clean motor oil to the gasket seal of your new replacement filter. This helps it form a tight seal.
6. Screw on the new filter by hand until the gasket lightly contacts the base, then tighten it an additional 3/4 to 1 full turn.
   CAUTION: Don’t over-tighten the filter, as that can damage the gasket. Tighten just enough to seal properly.

The hardest parts are done! Now just top off your engine oil and check for any leaks.

Adding New Motor Oil

With fresh oil drained and a new filter installed, refill your engine with clean oil:

1. Check your owner’s manual for the correct oil viscosity grade (thickness) and quantity needed for your vehicle’s engine. This varies by make and model.
2. Unscrew your vehicle’s oil filler cap then insert the end of your funnel into the exposed filler hole.
3. Slowly add the necessary quantity of new oil through the funnel, pouring carefully to avoid spillage. Avoid overfilling.
   TIP: Use a spout bottle when topping off to hit the exact fill mark. Stop pouring once the oil level reads full on your vehicle’s dipstick.
4. Replace the filler cap once the oil is topped off, twisting it on by hand until you feel it click securely into place.

You’re now ready to lower your vehicle, start the engine and check for any leaks before cleaning up!

Completing and Cleaning Up After an Oil Change

With fresh oil circulating, take a few final steps to ensure safety and proper cleanup after a DIY oil change:

Inspect for Leaks

1. Raise your vehicle, remove jack stands and carefully lower it to normal level ground.
2. Start your engine and let it idle for 1 minute. This will circulate the new oil.
3. Turn off your vehicle and wait 5 minutes to allow oil to drain down fully.
4. Check underneath your vehicle for any fresh oil dripping or leaks at the drain plug or oil filter areas. Tighten fittings further if you notice minor seeping.

Check Oil Level

1. Pull out and wipe your vehicle’s dipstick then reinsert it fully to measure the new oil level. The level should read between the marks indicating a full, proper fill is present.

Cleaning Up Properly

1. Make sure any used rags, the drain pan and tools are not leaking residual oil. Clean carefully with degreaser if needed.
2. Pour the drained used motor oil into approved recycling/disposal containers do not mix with other fluids or dispose of improperly.
3. Replace any tools or equipment in their proper storage locations so they are easily found next oil change.

And that’s it! When performed properly at regular intervals, changing your own car oil is an easy, cost-effective way to maintain your vehicle. Just be sure to dispose of waste properly and keep accurate maintenance logs.

Helpful Oil Change Tips and Tricks

Changing your own car oil for the first time can be intimidating, but gets much easier with practice. Here are some handy tips to make your oil changes smooth and hassle free:

• Use quality ramps for easy access underneath your vehicle rather than jacking up and supporting just one corner with jack stands which is prone to rocking.
• Apply penetrating oil to stubborn plugs/filters a day prior to soften them up for easy removal.
• Slide a section of garden hose over the oil drain plug to direct flow neatly into your drain pan without splatter.
• Set your container on a wheel dolly to conveniently roll it around rather than carrying heavy loads of fluid.
• Write the mileage and date of the oil change on a shop towel and stick it to the windshield as a handy service record.
• Take note of any metal debris on the magnetic drain plug indicating internal engine wear over time.
• Capture oil in labeled sanitized milk jugs for proper disposal rather than dumping down a household drain illegally.

Follow these DIY suggestions and your own oil changes will be streamlined and mess-free. Take pride handling this essential maintenance yourself at home.

Oil Change Safety Tips

While perfectly safe when done properly, an oil change involves working with hot fluids, heavy equipment and hazardous materials. Keep these safety guidelines in mind:

General Oil Change Safety

• Allow adequate time – Rushing leads to mistakes and injuries.
• Work when engine is cold – Avoid burns from hot oil and parts.
• Use jack stands – Securely support vehicle off the ground.
• Wear protective gear – Gloves, eyewear, clothes that cover skin.
• Carefully handle hot parts – Use rags when grasping components like the oil drain plug after draining.
• Make sure oil drain pan is properly secured underneath – Avoid spills.
• Have fire extinguisher nearby – As a precaution since you’ll be working around flammable liquids.
• Dispose of used oil responsibly – Don’t illegally dump it on the ground or down drains which harms the environment.

Avoiding Burns

• Wear gloves when unscrewing the oil drain plug – The initial blast of pressurized hot oil can cause instant 2nd degree burns if on bare skin. Even splatter can be painful.
• Allow oil to initially drain from a safe distance after removing plug – Stand clear those first 5 seconds when hot pressurized oil begins rapidly flowing out.
• Don’t overfill oil – Oil can blow out the fill hole when initially started if over the full line, spraying dangerously.

Preventing Vehicle Movement Injuries

• Use quality ramps on level ground – Rather than a lone hydraulic jack which can fail and collapse suddenly.
• Chock wheels with blocks – As an added precaution to avoid any rolling.
• Keep feet clear when lowering vehicle – Stay outside the wheel wells/bumper zone when bringing it down off ramps/jack stands in case it unexpectedly tips or drops.

Stay smart, take it slow and put safety first during every oil change. Avoid injuries by controlling your work environment and using caution when handling hot containers and fluids.
