Changing your engine oil at home saves money and keeps your car running smoothly for years. For the ninth-generation model, a 2015 honda civic oil change is a straightforward weekend job that takes about thirty minutes. You don't need a professional lift or an expensive pneumatic tool kit. Basic hand tools and a clean workspace are enough to get the job done right.
The standard 1.8-liter four-cylinder engine requires exactly 3.9 US quarts of oil when you swap out the filter. Gathering your supplies beforehand prevents frustrating mid-job trips to the auto parts store. You'll need a 17mm socket and ratchet, an oil filter wrench, a fresh crush washer, a drain pan, a funnel, and a clean shop towel.
Required Supplies and Specifications
Preparation determines whether your garage floor stays clean or turns into a messy cleanup zone. Let's look at the exact fluids and parts required for this specific vehicle architecture.
Viscosity and Fluid Capacity
Honda engineered this engine to run exclusively on thin synthetic lubricants. You must use 0W-20 full synthetic motor oil to protect internal components and maintain proper fuel economy. Conventional oils will shear down too quickly under modern operating temperatures.
- Standard 1.8L Engine Capacity: 3.9 US quarts (3.7 liters) with filter replacement.
- Si 2.4L Engine Capacity: 4.4 US quarts if your trim features the higher-performance powertrain.
- Approved Specifications: Look for API certification seals on the bottle to ensure compliance with factory standards.
Oil Filter Choices
Choosing a reliable filter protects your bearings from trapped contaminants. Factory replacements carry part number 15400-PLM-A02, but several aftermarket alternatives match exact thread pitch and bypass pressure.

- Wix 57356
- Mobil 1 M1-110
Preparation and Vehicle Elevation
Safety comes first whenever you slide underneath a passenger vehicle. Never rely solely on a hydraulic floor jack to support the car while your hands or face are underneath.
Park your car on flat, level concrete and engage the emergency brake firmly. Place wheel chocks behind the rear tires to prevent any rolling movement. Raise the front end using a sturdy hydraulic jack at the designated central front jacking point.
Slide heavy-duty jack stands under the factory pinch weld support points located directly behind the front wheels. Lower the car slowly until the weight rests securely on the stands. Give the vehicle a firm rock from side to side to verify absolute stability before crawling underneath.
Draining the Old Engine Oil
Warm oil flows faster and carries suspended particles out of the oil pan more effectively than cold oil. Run the engine for three minutes to warm the fluid, then shut it off. Pop the hood and unscrew the oil filler cap on top of the valve cover to vent the crankcase and speed up drainage.
Slide your drain pan underneath the oil pan plug located toward the back of the engine block. Grab your 17mm socket and turn the drain bolt counterclockwise to break it loose. Finish unscrewing it by hand while pushing inward slightly to keep oil from leaking past your fingers prematurely.
As the bolt clears the final threads, pull it away quickly so the hot stream lands directly in the center of your catch basin. Let the dark, used fluid drain completely for at least ten minutes until it drops to a slow, intermittent drip.
Inspect the old metal crush washer stuck to the drain plug or left on the pan surface. Peel it off and discard it. Thread a fresh crush washer onto the clean drain plug. Screw the bolt back into the oil pan by hand to prevent cross-threading, then tighten it with your ratchet to 29 lb-ft (39 Nm). Wipe away any stray drips around the drain area with a shop towel.
Replacing the Oil Filter
The factory filter sits near the front side of the engine block, making it relatively accessible compared to tightly packed European imports. Position your drain pan directly underneath the filter housing to catch any residual spills.
Turn the old filter counterclockwise using your filter wrench to break the initial seal. Spin it off by hand, keeping the open end tilted upward slightly to minimize spills as you slide it out of the engine bay.
Check the mounting base to ensure the old rubber O-ring gasket came off with the filter. Leaving the old gasket behind causes double-gasketing, which blows out immediately upon startup and dumps your entire oil supply onto the road.
Dip a clean finger into a bottle of fresh oil and smear a thin film around the rubber gasket of your new filter. This lubrication ensures a proper seal and makes future removal much easier. Screw the new filter onto the threaded stud by hand until you feel the rubber gasket contact the mounting base. From that exact point, turn it an additional three-quarters of a turn by hand. Never use a wrench to tighten a new filter, as over-tightening crushes the gasket and ruins the seal.
Pouring Fresh Oil and Checking Levels
Move to the top of the engine bay and insert your clean funnel into the valve cover opening. Pour in 3.5 quarts of your 0W-20 synthetic oil first. Remove the funnel and check the dipstick to establish a baseline reading.
Slowly add the remaining portion of the 3.9-quart total while monitoring the dipstick level frequently. Pull the dipstick out, wipe it clean with a shop towel, push it all the way back in, and pull it out again. The oil film should rest precisely between the upper and lower indicator dots.
Remove the funnel, screw the oil filler cap back on tightly, and clear all tools from the engine bay.
Resetting the Maintenance Minder System
After every service, you need to clear the electronic computer tracker so it calculates your next service interval accurately.
Turn your ignition key to the ON position without starting the engine, or press the engine start button twice without touching the brake pedal. Use the display controls on your steering wheel or the dash button to cycle through screens until you see the Engine Oil Life percentage.
Press and hold the select/reset knob or the steering wheel enter button for about ten seconds until the oil life display starts blinking. Release the button briefly, then press and hold it again for another five seconds until the percentage resets to 100%.
Common DIY Mistakes to Avoid
Avoiding simple errors protects your engine from catastrophic damage and saves you from unnecessary repair bills.
- Over-tightening the drain plug: Stripping the aluminum oil pan threads is an expensive mistake. Always use a torque wrench set to factory specifications rather than guessing by feel.
- Forgetting the crush washer: Reusing a flattened crush washer prevents a proper seal, leading to slow, persistent leaks that can empty your pan over time.
- Skipping the initial startup check: Always start the car and let it idle for thirty seconds while checking underneath for leaks before driving off. Keep an eye on the dashboard oil pressure warning light to ensure it turns off immediately.
- Improper disposal: Never pour used motor oil down storm drains or trash bins. Pour the old fluid into your empty oil containers and take them to a local auto parts store or municipal recycling center for free disposal.

Frequently Asked Questions
What happens if I accidentally put conventional oil in my 2015 Honda Civic?
Using conventional oil for a short commute won't instantly destroy your engine, but you should drain it and switch back to 0W-20 synthetic oil as soon as possible. Modern tight tolerances rely on the stability of synthetic polymers to prevent excessive wear during high-temperature driving.
How often should I change the oil in this model?
Under normal driving conditions, change your oil every 7,500 to 10,000 miles, or once a year. If you frequently drive in severe conditions—such as extreme dust, freezing temperatures, or heavy stop-and-go city traffic—cut that interval down to every 3,000 to 5,000 miles.
Why won't my oil life indicator reset?
If the display refuses to clear, you likely released the button too early during the sequence. Turn the ignition off, repeat the startup key position steps, and make sure you hold the button down continuously until the flashing numbers reset to 100 percent.
Do I really need to replace the crush washer every time?
Yes. Crush washers are designed to deform slightly under pressure to create a leak-proof seal. Reusing an old, flattened washer increases the risk of oil seepage. They cost pennies, so keeping a small pack in your toolbox is well worth the investment.
