Infiniti QX60 Oil Change: The Ultimate Guide

One of the most fundamental and crucial aspects of vehicle upkeep is the regular oil and filter change. For owners of the sophisticated Infiniti QX60, a common query often arises: does the Infiniti QX60 have an oil filter? The unequivocal answer is yes, absolutely! Like all modern internal combustion engines, your Infiniti QX60 relies on a meticulously designed oil filtration system to keep its heart – the engine – clean and performing optimally. This comprehensive guide is tailored for first-generation Infiniti QX60 luxury SUV owners (models 2013-2020), particularly those with the robust VQ35DE or VQ35DD 3.5L V6 engine, providing you with everything you need to know about changing your engine oil and replacing that all-important oil filter. We'll delve into why this maintenance is so vital, the specific requirements for your QX60, and a detailed, step-by-step procedure to empower you to tackle this task with confidence, ensuring your vehicle's engine longevity.

Understanding the intricacies of your vehicle's maintenance schedule is paramount. The engine oil acts as the lifeblood of your QX60, lubricating moving parts, preventing friction, cooling components, and even cleaning the engine by carrying away harmful contaminants. Over time, this oil degrades, losing its lubricating properties and becoming saturated with debris. This is where the oil filter plays its critical role, trapping these contaminants before they can circulate and cause wear. Neglecting oil and filter changes can lead to reduced fuel efficiency, increased engine wear, and ultimately, costly repairs or even premature engine failure. Regular servicing, as recommended by the manufacturer, is not just about keeping your car running; it's about preserving its value and ensuring a safe, reliable driving experience for many years to come.

Why Regular Oil Changes Are Non-Negotiable

Engine oil is more than just a lubricant; it's a multi-functional fluid designed to protect your engine under various operating conditions. Firstly, it reduces friction between moving parts, preventing wear and tear. Without adequate lubrication, metal-on-metal contact would quickly lead to overheating and catastrophic damage. Secondly, engine oil helps dissipate heat generated by combustion and friction, maintaining optimal operating temperatures. Thirdly, it cleans the engine by suspending dirt, sludge, and other impurities, carrying them to the oil filter where they are trapped. Finally, it provides a seal between the piston rings and cylinder walls, preventing combustion gases from escaping and maintaining compression.

Over time, the oil's additives break down, its viscosity changes, and it accumulates contaminants. This degradation diminishes its ability to perform these vital functions effectively. The oil filter, while highly efficient, also has a finite capacity for trapping particles. Once saturated, it can no longer filter effectively, and unfiltered oil may bypass it, circulating harmful debris throughout the engine. This is why replacing both the oil and the filter at recommended intervals is absolutely essential. It ensures that your Infiniti QX60's engine always has a fresh supply of clean, high-quality lubricant, prolonging its lifespan and maintaining its performance.

Decoding Your Infiniti QX60's Oil Requirements

Knowing the correct type and quantity of oil for your Infiniti QX60 is crucial for optimal engine health. For the 1st generation (2013-2020) Infiniti QX60 with the 3.5L V6 VQ35DE or VQ35DD engine, the recommended oil viscosity is SAE 0W-20. When performing an oil change with a filter replacement, the engine's oil capacity is approximately 5 1/8 U.S. quarts, which translates to about 4.8 litres. While this guide provides general specifications, it is always best practice to double-check your vehicle's owner's manual for the most accurate and up-to-date information regarding oil capacity and viscosity recommendations, as specifications can sometimes vary slightly by model year or region.

When it comes to the type of oil, the preferred choice for your QX60 is typically full synthetic oil. Synthetic oils are engineered to provide superior performance and protection compared to conventional mineral oils. They offer better stability at extreme temperatures, enhanced lubricating properties, and are less prone to breaking down over time. This often allows for longer oil change intervals, which can be convenient for busy drivers. While some vehicles might permit the use of synthetic blends or conventional oil, synthetic is generally recommended for modern engines like those found in the QX60 due to its advanced protective qualities. If you opt for conventional oil, you may need to perform changes more frequently. The decision between synthetic and conventional often depends on your driving habits and the specific recommendations in your owner's manual.

Compatible Oil Filters for Your Infiniti QX60

When replacing your oil filter, it's important to use a compatible, high-quality component. Here's a list of commonly available and trusted replacement oil filters that fit the Infiniti QX60 3.5L V6 engine, along with their part numbers:

Always ensure the filter you choose is compatible with your specific model and engine. A new OEM oil drain bolt washer (Nissan part number: 11026-JA00A) is also recommended for replacement if your existing one appears damaged or worn.

DIY Oil & Filter Change Guide for Your Infiniti QX60

Changing your own oil and filter can be a rewarding experience, saving you money and giving you a deeper understanding of your vehicle. However, it's paramount to prioritise safety procedures throughout the process. Ensure you have all the necessary tools and supplies before you begin.

Essential Tools and Supplies:

• New engine oil (SAE 0W-20, approx. 5 1/8 US quarts / 4.8L)
• New compatible oil filter (refer to table above)
• Used oil catch container (at least 5-litre capacity)
• 14mm socket with a 3/8" drive ratchet
• Flat head screwdriver
• Floor jack
• At least two sturdy jack stands
• Wheel chocks
• Automotive funnel
• Clean rags or shop towels
• Optional: Lisle 63600 oil filter wrench (highly recommended for stubborn filters)
• Optional: Torque wrench (for precise tightening)
• Safety glasses and gloves

Step-by-Step Procedure:

1. Preparation and Safety First

Begin by parking your Infiniti QX60 on a level, solid surface. Shift the transmission into "Park" and switch off the ignition. Crucially, engage the emergency or parking brake. For added safety, place wheel chocks on both sides of the rear tyres to prevent any unintended movement of the vehicle. It's often beneficial to perform an oil change while the engine is still warm (but not scalding hot), as this allows the old oil to drain more quickly and ensures contaminants are still suspended within it. Open the bonnet and locate both the oil filler cap and the dipstick. Twist off the oil filler cap in a counterclockwise direction and lift the dipstick out by an inch or two. This action helps to prevent a vacuum from forming in the engine, allowing the old oil to drain more efficiently.

2. Raising the Vehicle

While some might attempt to access the drain bolt without raising the vehicle, it is significantly easier and safer to lift the front of the SUV. Using your floor jack, carefully raise the front passenger side of the vehicle. Once it's at an adequate height, securely support it with at least two robust jack stands. Never, under any circumstances, rely solely on the floor jack to support the vehicle while you are working underneath it. Ensure the jack stands are placed on solid frame points and are stable before proceeding.

3. Draining the Old Oil

Slide your used oil catch container directly beneath the oil drain bolt. The black metal oil pan is located closer to the passenger side of the vehicle, adjacent to the exhaust pipe. The drain bolt itself is situated on the rear of the oil pan, with its head facing towards the back of the SUV. Using your 14mm socket and 3/8" drive ratchet, carefully loosen the drain bolt in a counterclockwise direction. Be extremely cautious at this stage; depending on how long the engine has been warm, the old oil might still be hot enough to cause burns. Once loose, remove the drain bolt by hand and allow the old oil to drain completely into the catch container. This typically takes anywhere from five to ten minutes, or until the flow reduces to an occasional drip.

Once the oil has drained, inspect the washer or "gasket" on the drain bolt. If it appears damaged, flattened, or worn out, it is highly recommended to replace it with a new one, such as the OEM Nissan part number 11026-JA00A. Wipe off any debris from the drain bolt and the area around the drain hole. To prevent cross-threading, spin in the drain bolt a few turns by hand in a clockwise direction until you feel it catch properly. Then, using your 14mm socket and ratchet, tighten the drain bolt until it is snug. If you have a torque wrench, tighten it to the service manual specification of 22 to 29 lb-ft of torque. Always double-check that the oil drain bolt is securely tightened before moving on.

4. Replacing the Oil Filter

The oil filter on your Infiniti QX60 is located on the passenger side of the engine, directly below the crankshaft pulley. To gain better access to this area, you might find it helpful to turn the steering wheel all the way to the right, which will move the front passenger wheel out of the way slightly.

You will need to access the oil filter by removing or partially moving the black plastic cover, often referred to as the "splash shield" or "splash guard." This shield is typically held in place by four plastic fasteners. If you're looking for a quicker method, you can often just remove the two lower pop rivets and lift the panel to create enough space to reach the filter. To remove these fasteners, use your flat head screwdriver to pry out the smaller round button in the centre first, which unlocks them. Then, pry out the base of the fasteners. Once the fasteners are removed, pull off the plastic splash guard and set it aside in a safe place, along with the pop rivets.

With the splash shield out of the way, you'll clearly see the old oil filter situated in front of the drive shaft and below the serpentine belt. While you might be able to unscrew it by hand (sometimes by wrapping an old belt around it for grip), a specialised oil filter wrench, such as the Lisle 63600, is highly recommended. These wrenches make removing stubborn or overtightened filters much easier. Twist off the old oil filter in a counterclockwise direction. Allow any remaining oil from the filter and its receptacle to drain out for a few minutes into your catch container.

Before installing the new filter, dip your finger into some new engine oil and carefully lubricate the rubber o-ring gasket on the new oil filter. This lubrication is crucial as it helps the filter form a better seal, prevents oil leaks, and will make it significantly easier to remove during your next oil change. It's also vital to ensure that the old o-ring gasket from the previous filter is not still stuck to the engine block; if it is, remove it. Spin on the new oil filter in a clockwise direction until it is snug. Typically, this means tightening it about 1/4 to 1/3 of a turn past finger tight. The owner's manual specification for tightening the oil filter is usually between 11-15 lb-ft of torque. Avoid overtightening the filter, as this can damage the rubber o-ring and lead to an oil leak.

5. Reassembly and Refilling

Once the new filter is securely in place, line up the splash shield and re-insert the four plastic pop rivet fasteners. Push in the buttons in the centre of the fasteners to lock them into place, ensuring the engine cover is securely attached. If you raised the SUV on jack stands, carefully lower it back to the ground using your floor jack, removing the jack stands once the vehicle is safely supported by the jack, and then fully lowering it.

Insert your automotive funnel into the oil fill hole. It's always better to initially pour slightly less oil than the maximum capacity, as overfilling an engine can cause damage to seals, gaskets, and other components. For the Infiniti QX60 3.5L V6, the total capacity with a new filter is 5 1/8 U.S. quarts (4.8L). Begin by slowly pouring in about 4.5 to 4.75 U.S. quarts of the new SAE 0W-20 oil into the funnel. Once the initial amount is poured, temporarily replace the oil filler cap and tighten it clockwise. Push the dipstick back fully into its tube.

Start the engine and allow it to run for a few minutes, letting it warm up to operating temperature. This allows the new oil to circulate throughout the engine and fill the new oil filter. Turn off the ignition and let the new oil drain back down to the oil pan for at least 10 minutes. Then, pull out the dipstick, wipe it clean with a rag, fully re-insert it, and pull it out again to check the oil level. The oil level should ideally be at or very close to the "H" mark or the top of the cross-hatched area on the dipstick, which indicates the maximum or full line. If necessary, slowly pour in small amounts of additional oil and repeatedly check the level on the dipstick until it reaches the correct mark. Remember, you may not need to pour in the entire 5 1/8 U.S. quarts to reach the full mark, so always check the dipstick accurately.
