Performing your own engine oil change can seem daunting at first, but with the right guidance, it's a straightforward task that can save you money and give you a deeper understanding of your vehicle. This guide is specifically tailored for owners of the 2017-2022 Honda CR-V equipped with the 1.5-litre turbocharged engine, offering a detailed, step-by-step process designed for those with absolutely no prior experience. By following these instructions carefully, you'll be able to confidently carry out a routine oil service, ensuring your Honda runs smoothly and efficiently for years to come.

Safety First: Essential Precautions Before You Begin

Before you even think about reaching for a spanner, it's crucial to prioritise safety. Working with vehicles involves potential hazards, and taking the necessary precautions will protect you from injury and ensure a safe working environment. Always refer to your owner's manual for manufacturer recommendations on fluid types and service intervals, as this guide serves as a general resource.

Per Occupational Safety and Health Administration (OSHA) guidelines, you must wear personal protective equipment (PPE) at all times. This includes, but is not limited to: safety glasses to protect your eyes from splashes or debris, latex gloves to keep your hands clean and protected from chemicals, and closed-toe shoes to prevent foot injuries. It's also wise to remove all jewellery from your ears, neck, wrists, and hands; loose items can get caught in moving parts. Furthermore, refrain from smoking or having open flames near your workspace, as you will be working with flammable liquids.

Finally, consider the environmental impact. Locate a designated disposal site for used engine oil and filters that complies with local environmental regulations. Most local auto-part stores or council recycling centres offer facilities for disposing of these hazardous fluids responsibly. Never pour used oil down drains or onto the ground.

Tools and Equipment Required

Having all the necessary tools and materials at hand before you start will make the process much smoother and more efficient. Here’s a comprehensive list of what you’ll need:

Step-by-Step Engine Oil Change Instructions

1. Preparing the Vehicle and Area

Begin by ensuring your vehicle is parked on a flat, level surface. Engage the parking brake and place wheel chocks behind the rear wheels to prevent any accidental movement. Next, open the bonnet of the vehicle. The bonnet release handle is typically located on the driver’s side kick panel, often below the fuel door release handle. Once released, lift the bonnet and secure it with the prop rod, ensuring the plastic tip is fully seated in its designated hole to prevent it from falling.

Locate the oil filler cap on the passenger side of the engine compartment. It’s usually clearly labelled "SAE 0W-20" and often orange. Remove this cap and place it somewhere safe. Removing the cap now helps the oil drain more freely later by allowing air to enter the system.

2. Accessing the Undercarriage: Skid Plate Removal

To access the oil filter and drain plug, you'll need to remove the skid plate from the underside of the vehicle. You might find it more comfortable to lie on an old blanket or cardboard. The skid plate is typically held in place by a combination of fasteners: six Phillips head screws and two 10mm bolts. Carefully remove all eight fasteners. Once the fasteners are out, the skid plate usually needs to be pushed slightly towards the rear of the vehicle to release any sliding tabs. You can use an opening in the plate as a handle to manoeuvre it. Once removed, set the skid plate aside and place all fasteners in a bag or container, clearly labelled for re-installation. This prevents them from getting lost.

3. Locating the Oil Filter and Drain Plug

With the skid plate removed, you can now clearly identify the oil filter and the oil drain plug. On the 2017-2022 Honda CR-V, the original equipment manufacturer (OEM) oil filter is typically dark blue. It is located towards the front of the vehicle. The oil drain plug is usually to the right (driver's side) of the oil filter, on the bottom of the oil pan. For added clarity, the oil pan often has raised lettering indicating "ENGINE OIL" near the drain plug.

4. Draining the Old Oil

This is where things can get a bit messy, so be prepared with your drain pan and rags. First, position your drain pan directly underneath the oil filter. You'll notice an indentation in the oil pan designed to guide oil from the filter into the pan. Using your oil filter wrench, turn the oil filter counter-clockwise until it is loose enough to turn by hand. Continue loosening it by hand until oil begins to leak from the filter area into the drain pan. Allow it to drain for approximately 45 seconds until the flow significantly slows or stops. Then, carefully remove the oil filter completely and place it immediately into the drain pan to catch any remaining drips.

Next, reposition the drain pan so its front edge is just below the drain plug, with the back portion pointed towards the rear of the vehicle. This is crucial for catching the initial gush of oil that will stream out horizontally once the plug is removed. Take your 17mm wrench or socket and ratchet and turn the engine oil drain bolt counter-clockwise. Once it's loose enough to turn by hand, slowly continue turning it until oil starts to leak from the drain plug hole. Be ready, as the oil will come out quickly. You can allow the drain plug to fall into the drain pan. Let the oil drain completely until it only drips occasionally. This can take several minutes.

5. Installing the New Drain Plug and Oil Filter

Once the oil has finished draining, retrieve the drain plug from the drain pan and clean it thoroughly with a rag. Remove the old aluminium crush washer from the bolt. This light grey, flattened ring is designed to deform and create a tight seal when tightened. It is a single-use item and must be replaced with a new one to prevent leaks. Install the new 14mm aluminium crush washer onto the drain plug. Hand-tighten the engine oil drain bolt clockwise into the oil pan. Once it's hand-tight, use your 17mm wrench or socket. Tighten the bolt until you feel it get tight, then slightly loose again – this is the "crushing" effect of the washer. The proper torque specification for the drain plug is approximately 29 lbf-ft (pound-feet). After tightening, attempt to turn the drain bolt by hand; it should not be able to be turned.

Now, prepare your new oil filter. Remove it from its plastic packaging. Crucially, rub a small amount of new or old engine oil onto the rubber O-ring seal of the new filter. This lubrication ensures the filter seals completely and prevents it from binding during installation, which could lead to leaks. Install the new oil filter by turning it clockwise onto the protruding threads of the filter housing. Once the filter contacts the housing, you'll feel resistance. Continue tightening by hand for an additional ¼ to ½ turn. You should feel the rubber O-ring squish down slightly, creating a firm seal. This feeling is similar to the crush washer 'crushing' during the drain plug installation.

After both the oil filter and drain plug are re-installed, thoroughly clean both areas with a rag. You can use a household cleaner to help dry any residual oil. This is important to ensure no oil spots appear on your driveway later, which could mistakenly indicate a leak.

6. Refilling with New Engine Oil

Place your funnel into the oil filler location on top of the engine, where you removed the oil cap earlier. For the 2017-2022 Honda CR-V 1.5L turbocharged engine, the recommended oil type is SAE 0W-20 synthetic engine oil. The specified capacity for a routine oil and filter change is 3.7 US Quarts (approximately 3.5 litres). Carefully pour in the first three quarts of new oil. Then, slowly pour in the remaining amount, checking your oil level as you go to avoid overfilling.

7. Post-Change Checks and Final Steps

Once the oil is poured, re-install the oil filler cap and tighten it by hand. Before starting the vehicle, ensure all tools and objects are removed from the engine bay and from underneath the vehicle. Start the engine and allow it to run for approximately five seconds until the low oil pressure warning light on your dashboard disappears. Then, turn the engine off immediately. Carefully check for any leaks around the oil filter and the oil drain plug. If you observe any leaks, re-check that the oil filter and drain plug are properly tightened as described in the previous installation steps.

Re-install the skid plate by placing it back into position and sliding it towards the front of the vehicle to engage any tabs. Then, re-install the six Phillips head screws and two 10mm bolts, turning them clockwise into their previous locations. Hand-tighten these fasteners until you feel resistance, then give them about half a turn more. Do not over-tighten them, as this can strip the threads. When installed correctly, the skid plate should fit snugly without any gaps between the mating surfaces.

Finally, verify the engine oil level using the dipstick. Remove the dipstick, wipe it clean with a rag, then re-insert it fully into its tube. Remove it again and observe the wet line from the engine oil. This line should be located between the two black lines on the end of the dipstick, ideally closer to the upper (maximum) line. This is also a good opportunity to check other fluid levels in your engine compartment, such as brake fluid, engine coolant, and windscreen washer fluid. Each reservoir has clear "min-max" lines. You can refill the windscreen washer fluid with regular tap water if needed.

Close the bonnet, ensuring it latches completely. You can test this by gently pulling up on the bonnet to confirm it won't open.

8. Resetting the Oil Life Monitor and Test Drive

After completing the physical oil change, you need to reset the oil life monitor in your vehicle's infotainment system. Start the vehicle and navigate to the "settings" menu. Select "vehicle settings," then "maintenance information," and finally press "reset." This will set the oil life back to 100%, allowing your vehicle to accurately track its next service interval.

As a final step, take your vehicle for a short test drive. Pay attention to how it drives and listen for any unusual noises. This ensures all systems are performing as designed and confirms there are no hidden issues or leaks that only appear under driving conditions. Congratulations, you've successfully completed an engine oil change on your Honda CR-V!

Frequently Asked Questions (FAQs)

How often should I change the engine oil in my Honda CR-V?

Honda generally recommends an oil change every 7,500 to 10,000 miles or once a year, whichever comes first, for normal driving conditions. However, your vehicle's maintenance minder system is the most accurate guide, as it calculates oil life based on driving habits and conditions. Always refer to your owner's manual for the most precise recommendations.

Can I use a different oil viscosity or type than SAE 0W-20 synthetic?

It is strongly recommended to stick to the manufacturer's specified oil type and viscosity, which for the 2017-2022 Honda CR-V 1.5L turbo is SAE 0W-20 synthetic. Using a different type could lead to reduced fuel efficiency, increased engine wear, or even engine damage, as the engine is designed to operate optimally with this specific oil. Consult your owner's manual if you live in extreme climates, as there might be alternative recommendations.

Why is it so important to replace the crush washer?

The crush washer is a single-use sealing component for the oil drain plug. It's made of a soft metal, typically aluminium, that deforms or "crushes" when the drain plug is tightened, creating a tight, leak-proof seal. Reusing an old crush washer can result in an imperfect seal, leading to slow oil leaks over time, which can be costly and dangerous if the oil level drops too low.

What should I do if I over-tighten the oil drain plug or filter?

Over-tightening the drain plug can strip the threads in the oil pan, which is a very serious and expensive repair. Over-tightening the oil filter can damage the filter housing or its O-ring, leading to leaks. If you suspect you've over-tightened, it's best to consult a professional mechanic immediately. Prevention is key: always use a torque wrench for the drain plug if possible, and for the filter, tighten by hand plus the specified ¼ to ½ turn past contact.

Where can I dispose of my used engine oil and filter?

Used engine oil and filters are hazardous waste and must be disposed of properly. Most local authority recycling centres have facilities for used oil. Many auto parts stores also accept used oil for recycling. Never pour used oil down drains, onto the ground, or mix it with other fluids. Check with your local council or environmental agency for specific disposal guidelines in your area.

How does the oil life monitor work and why do I need to reset it?

The oil life monitor in your Honda CR-V is part of the vehicle's onboard computer system. It tracks various factors such as engine temperature, revolutions, and driving conditions to estimate the remaining life of your engine oil. After an oil change, you must manually reset this system so it can begin a new calculation from 100% oil life. Failure to reset it means the system will continue to display the old oil life, potentially triggering maintenance reminders prematurely or, worse, not alerting you when the oil genuinely needs changing.
