Changing Your Engine Oil and Filter – A Critical DIY Task
One of the most essential maintenance tasks for prolonging your engine’s life is changing the engine oil and oil filter at regular intervals. Your vehicle’s owner’s manual specifies the required oil change frequency, typically every 5,000-10,000 miles depending on driving conditions and engine design.
Neglecting regular oil changes causes excess friction and contamination buildup inside the engine, accelerating wear on critical components like bearings and piston rings. This can lead to reduced fuel economy, higher operating temperatures, oil leaks, and ultimately catastrophic engine failure down the road.
Changing the oil yourself only takes about 30-45 minutes for most vehicles. It saves paying shop labor rates that can run $50-100 or more for this basic service. Doing it yourself also ensures you use high quality oil of the proper viscosity and amount for your particular engine.
Here are some tips and a detailed overview of the entire oil change process:
Supplies Needed
Gather the following tools and supplies before raising your car to complete an oil change:
- Oil filter wrench – Required for loosening the old oil filter for removal. Models that grip from the top or bottom are available. Ensure you have the correct size for your filter.
- Floor jack and jack stands – Safely raise the front of the car on secure jack stands to gain access underneath and properly drain the old oil out. Never get under a vehicle supported only by a jack-use stands.
- Drain pan – A pan with at least a 5-quart capacity is recommended to catch the old oil without spilling. The wider the pan the better.
- Funnel – Used after the new filter is installed to carefully pour new oil into the engine’s fill hole. A small funnel directs oil and minimizes spills.
- Replacement oil filter – Double-check your owner’s manual or filter label to ensure you get the specific oil filter recommended for your engine. Avoid universal fit filters.
- New engine oil – Refer to your owner’s manual for the factory-recommended oil viscosity and the amount required by your engine after draining the old oil. Most take 4-6 quarts of standard 5W-30 or similar viscosity oil.
Step-by-Step Oil Change Procedure
Here is an overview of the complete process for safely changing your own engine oil:
- Park your car or truck on a flat, level surface like a driveway or garage floor. Set the parking brake. Jack up the front end and support it securely on jack stands for maximum drainage capability. The engine oil pan itself may be graded toward the rear.
- Locate the oil drain plug underneath towards the rear of the oil pan. It may be obvious or you may need to trace oil lines from the filter housing. Place your drain pan directly underneath. Loosen the plug carefully using your wrench or ratchet until oil begins to drain out.
- Allow the dirty oil to drain fully until the flow slows to an intermittent drip. Avoid reinstalling the plug too soon. The more used oil you drain out, the better. Depending on the oil level and pan design, this can take 5-10 minutes. Be patient.
- Once drained, wipe the drain plug threads with a clean rag to remove the oil. Then tighten it back into the oil pan snugly by hand until secure. Avoid over-tightening.
- Next, locate the oil filter housing on the engine. Using your specialized filter wrench or filter cup-type wrench, turn the filter counterclockwise to loosen and unscrew it fully. Allow any residual oil still inside the housing to drip into your drain pan.
- Before installing the new replacement filter, lubricate the filter’s rubber gasket with a thin coat of fresh, clean oil. This ensures a proper seal and allows tightening it by hand properly later. Don’t apply too much oil.
- Screw on the new oil filter by hand turning it clockwise until the gasket contacts the housing surface. Tighten it another 3/4 to 1 full turn further to seat it. Do not overtighten filters since that can damage the gasket.
- Lower the vehicle back to the ground once the filter is tightened. Be sure to remove jack stands and tools from under the car. Open the hood and locate the engine oil fill cap. Unscrew the cap and insert your funnel into the fill hole.
- Add the recommended quantity of new oil (consult your owner’s manual) slowly in stages, allowing it to drain down into the engine between pours. Avoid spilling oil in the fill hole. Check the dipstick periodically to monitor when full level is achieved.
- Once the dipstick reads at the “Full” line, wipe any spillage around the oil fill hole using rags. Properly screw on the oil fill cap until it clicks. Close the hood when finished.
- Check under the engine for any leaks at the drain plug or oil filter areas. Small seepage may occur initially at the new filter but should stop within 30 seconds once pressure is established.
- Responsibly dispose of the drained old oil in the used oil recycling tank at auto parts stores or hazardous waste collection facilities. Never dump down a household drain. Reset your car’s oil change reminder light or sticker before driving.
And that concludes the oil change process! While intimidating initially, with the right tools and patience this is very achievable for any car owner. You’ve just saved $40-75 that a shop would charge for basic labor on an oil change service.
Oil Change Frequency Intervals
Most modern engines have an oil change interval of 5,000-10,000 miles recommended in the owner’s manual. Shorter intervals apply to engines routinely operating under heavy loads or extreme conditions.
For many drivers, sticking with a 5,000-mile interval provides an extra margin of safety and peace of mind to account for any unknown variables. The cost of the additional oil changes is cheap engine insurance.
Synthetic oils tout the capability to operate for up to 15,000 miles between changes. But consider dropping back to a lower 10,000 mile interval for severe service schedules. A $25 oil change is cheap insurance against premature engine wear.
Disposing of Used Motor Oil
Be sure to responsibly dispose of old drained motor oil – never dump down household drains, directly into the ground soil, or into neighborhood trash bins. Used oil can contaminate groundwater and contains heavy metals harmful to the environment.
Instead, recycle it for free using these methods:
- Most auto parts stores allow depositing used oil in special on-site recycling tanks
- Local government hazardous waste collection days often accept used motor oil
- Some repair shops will take small amounts of waste oil to recycle if you ask politely
- Larger volumes can be recycled through special waste handlers for a small fee
Proper oil disposal prevents pollution and protects the environment. Avoid fines by keeping documentation like receipts for recycling drop-offs.
Replacing Your Air Filter – A Quick 5 Minute Fix
Replacing the engine air filter at least annually ensures maximum airflow to your engine for good performance and mileage. A restricted, dirty air filter causes easily avoidable problems.
This is one of the absolute easiest and most essential DIY car repairs you can do. Locating the air filter housing and swapping in a new filter takes only about 5-10 minutes on most vehicles with simple hand tools. Yet shops would charge $20+ just for labor on this basic service.
Here are tips for properly replacing air filters to keep your engine breathing freely:
Air Filter Locations
Engine air filters are positioned along the intake piping leading to the throttle body:
- On many older vehicles, a large round filter housing can be found affixed to the fender well for easy access. Just unlatch the clips and open the lid.
- On more modern cars, the airbox is commonly located centrally behind the grille and front bumper cover. Removable access panels or twisting clamps allow opening the housing.
- Some air filters insert into the front passenger compartment kick panel area under the glove box. Consult your owner’s manual if location isn’t obvious.
Selecting Replacement Filters
Avoid universal fit filters that do not properly seal the housing. Instead, use genuine factory filters or trusted aftermarket brands engineered specifically for your vehicle like K&N, Wix, or Fram. These cost little more but fit precisely right.
Double check markings on your factory air filter or specifications in the owner’s manual to get the right replacement filter. Note direction of airflow arrows printed on most filters when installing.
Air Filter Change Steps
Changing an air filter involves three simple steps:
- Release the clips or retainers securing the airbox lid or access panel and open the housing. Carefully remove the old dirty filter for disposal, taking care not to knock any leaves/debris into the intake tract.
- Before inserting the new filter, inspect the interior housing walls for any leaves, seeds, or dirt accumulation. Clean these areas by wiping with a dry rag to prevent contaminants entering the engine. Avoid spraying any liquids near the filter port.
- Insert the new air filter into the housing cavity by gently sliding it into place. Confirm it is fully seated within the gasket. Close and fasten the airbox lid or access panel once the new filter is installed. Avoid running the engine without the filter installed.
Perform air filter inspection whenever you change the engine oil. Replace when you notice darkened, bent pleats or obvious dirt buildup on the old filter. This simple 5 minute fix extends to 30,000 miles or beyond when done regularly.
Cabin Air Filter Replacement
Don’t neglect the cabin air filter when replacing the engine air filter. The cabin filter cleans airflow entering your vehicle’s interior and HVAC system. It uses a similar pleated paper filter that requires periodic replacement, typically every 15,000-30,000 miles.
Consult the owner’s manual for cabin filter access behind the glovebox or under the cowl. Swap it when changing the engine air filter. A clean cabin filter improves comfort and reduces lingering odors.
Installing New Windshield Wiper Blades
Over time sitting parked in the elements, windshield wiper blades deteriorate, crack, lose tension, and streak rather than clear water effectively. Annual wiper blade replacement restores streak-free visibility for safe driving in rain and snow.
Upgrading to winter blades with protective rubber shells can further combat icy buildup in cold climates. The benefit is keeping your field of vision crystal clear. Here are the simple steps for swapping wiper blades yourself:
When to Replace Wiper Blades
Inspect wiper blades occasionally for signs they need replacement:
- Hardened or cracked rubber from UV exposure and age
- Streaks or chatter marks left on the windshield
- Areas that don’t fully contact the glass
- Permanent blade curvature when not activated
Wiper inserts are inexpensive – replace in pairs yearly before winter as preventative maintenance.
Removing the Old Wiper Blades
- Lift the wiper arm away from the windshield until it locks into a vertical position. This gives access to the wiper blade underneath.
- Locate the small locking tab that connects the wiper blade to the arm. You may need to slide down a sleeve. Press the tab to release the connector and slide the old blade downward out of the arm channel.
- Slide the new replacement wiper blade up into the arm opening. You may need to initially angle it diagonally from the side before straightening.
- Push upward until the connector clips back into the arm and locks in place. Tug testing ensures proper securement.
- Carefully lower the wiper arm back onto the windshield and check for proper contact across the length of the blade. The process takes only 2-3 minutes per wiper!
DIY Wiper Blade Cost Savings
Shop labor rates typically run $40-50 just to have a technician perform this very simple wiper blade swap. DIY replacement using comparable-quality brands saves tremendously.
You also control using advanced blade materials like graphite-coated, low-friction rubber for smoother wiping. Explore hybrid and winter blades for added value.
Final Takeaways on DIY Car Repairs
With very little specialized skill, basic maintenance like oil changes, air filter and wiper blade replacement is doable right in your own garage or driveway with substantial savings. Investing in quality tools like jacks and jack stands pays for itself after just a few repairs.
But know your limits – more complex repairs like transmission servicing, timing belts, flushes, brake hydraulic system bleeding, and wheel alignments still require leaving it to professional technicians with proper equipment. Use good judgement on when DIY is appropriate.
Follow instructions carefully, work safely with jack stands, and dispose of fluids properly. A little time investment saves you money while giving you intimate knowledge of your car’s maintenance needs.
Soon you’ll confidently handle basic upkeep yourself and know exactly what’s going on under the hood. Understanding warning signs of problems and how components operate builds valuable mechanical skills as well. It just takes some patience and the willingness to get hands dirty!
