Changing the engine oil on a 2014 Infiniti QX60 requires precise measurements and the correct fluid specifications to keep its 3.5L V6 engine running smoothly. The total engine oil capacity for this vehicle is 5.1 US quarts (4.8 liters) when including the oil filter change. Using the wrong viscosity or overfilling the crankcase can lead to poor performance, diminished fuel economy, or internal mechanical wear.
This guide provides the exact specifications, a step-by-step replacement procedure, and critical tips to help you avoid common mistakes during your next service interval.
Technical Specifications and Requirements
Before sliding under your SUV, gather the correct components. Using manufacturer-approved fluids ensures your engine maintains optimal hydraulic pressure and thermal regulation.
Oil Type and Viscosity
Infiniti specifies 5W-30 engine oil for the 2014 QX60 under normal operating conditions. For optimal cold-weather starting and high-temperature protection, choose a fully synthetic oil that meets API certification standards and ILSAC specifications.
Fluid Capacities
- With oil filter change: 5.1 US quarts (4.8 liters)
- Without oil filter change: 4.8 US quarts (4.5 liters)
- Oil pan drain plug torque: 25 ft-lb (34 Nm)
- Oil filter tightening: Hand-tighten plus three-quarters of a turn (do not over-tighten)
Recommended Tools and Supplies
- 5.1 quarts of 5W-30 synthetic engine oil
- OEM replacement oil filter (such as Nissan part number 15208-65F0E or equivalent high-grade filter)
- 14mm socket and ratchet
- Oil filter wrench
- Drain pan and funnel
- Clean shop rags or paper towels
- Jack stands and a hydraulic floor jack (or automotive ramps)
Step-by-Step Oil Change Procedure
Perform this procedure on a level surface after running the engine for a few minutes to warm the oil, which helps contaminants suspend and drain more thoroughly.
Step 1: Elevate and Secure the Vehicle
Safely raise the front of your Infiniti QX60 using a reliable hydraulic floor jack. Secure the vehicle with heavy-duty jack stands and block the rear wheels. Never work beneath a vehicle supported only by a hydraulic jack.
Step 2: Locate and Drain the Old Oil
Position your drain pan beneath the oil pan drain plug. Use your 14mm socket to loosen the drain plug counter-clockwise. Unscrew it by hand carefully while pushing inward slightly to prevent hot oil from rushing out past your fingers. Let the oil drain completely until it slows to a steady drip.
Step 3: Remove and Replace the Oil Filter
The oil filter on the 3.5L V6 engine is located near the front bottom of the engine block. Place your drain pan underneath the filter mount. Unscrew the old filter counter-clockwise using an oil filter wrench if it's stuck.
- Wipe the mounting surface clean with a lint-free rag.
- Dip a clean finger into a bottle of fresh oil and smear a thin film over the rubber gasket of the new filter.
- Thread the new filter onto the housing by hand until the gasket seats firmly, then turn it an additional three-quarters of a turn.
Step 4: Reinstall the Drain Plug
Inspect the drain plug washer. If it's crushed or worn, replace it with a new crush washer to prevent slow leaks. Thread the drain plug back into the oil pan by hand to avoid cross-threading, then tighten it to 25 ft-lb using a torque wrench.
Step 5: Add Fresh Oil
Remove the oil filler cap under the hood. Insert a clean funnel and pour in 4.5 quarts of fresh 5W-30 synthetic oil. Remove the funnel, replace the oil filler cap securely, and start the engine. Let it idle for roughly 30 seconds while you check underneath for any leaks around the filter and drain plug.
Turn the engine off, wait five minutes for the oil to settle back into the pan, and pull the dipstick. Wipe it clean, reinsert it fully, and check the level. Slowly add the remaining oil in small increments until the level reaches the upper notch on the dipstick, bringing your total to roughly 5.1 quarts.
Common Mistakes to Avoid
Even experienced DIYers occasionally run into preventable issues during a routine service. Keep these pitfalls in mind:
- Over-tightening the drain plug: Stripping the aluminum threads on the oil pan is an expensive headache. Always use a torque wrench set to 25 ft-lb instead of guessing by muscle.
- Double-gasketing the filter: Sometimes the old rubber O-ring sticks to the engine mounting pad when you remove the old filter. If you screw a new filter on top of the old gasket, it will blow out immediately and dump your entire oil supply. Always check the old filter face.
- Ignoring fluid disposal: Pouring used motor oil down storm drains harms local ecosystems. Pour your old oil into a sealed container and take it to a local auto parts store or recycling center for proper disposal. You can find convenient drop-off locations through organizations like the American Petroleum Institute.
Frequently Asked Questions
How often should I change the oil in a 2014 Infiniti QX60?
If you use high-quality synthetic oil, change it every 7,500 miles or 6 months, whichever comes first. If you drive in severe conditions—such as heavy stop-and-go city traffic, dusty environments, or frequent short trips—consider shortening the interval to every 5,000 miles.
Why does my oil level read low between changes?
Modern V6 engines can consume minor amounts of oil over thousands of miles, especially as mileage climbs past 100,000 miles. Check your oil level manually using the dipstick every other time you fill up with gas to catch consumption early.
Can I use conventional oil instead of synthetic?
While conventional 5W-30 oil will technically lubricate the engine, synthetic oil provides superior thermal stability and resists breakdown much better under high heat. Nissan and Infiniti engineering guidelines strongly recommend synthetic formulas for long-term component protection. For official manufacturer maintenance schedules, consult the Nissan Owner Portal.
What happens if I accidentally overfill the engine oil?
Adding too much oil causes the spinning crankshaft to whip the liquid into foam. Aerated oil loses its hydraulic pressure and lubricating properties, which can lead to lifter noise, overheating, or blown engine seals. If you overfilled by more than half a quart, drain some out using a fluid extractor or by loosening the drain plug briefly.
