While a professional oil change is always an option, understanding the process empowers you to ensure the job is done correctly and potentially save money. This guide provides a technical breakdown of performing an oil change on a 2015 Nissan Murano, highlighting key components and procedures.

Understanding the Lubrication System

Before diving into the procedure, let's examine the engine's lubrication system. Its primary function is to reduce friction between moving parts, minimizing wear and tear. Engine oil performs several critical roles:

Lubrication: Creating a thin film between surfaces like pistons and cylinder walls, crankshaft bearings, and camshaft journals.
Cooling: Absorbing heat generated by friction and combustion, transporting it away from critical areas.
Cleaning: Carrying away contaminants like carbon deposits, metallic particles, and sludge.
Sealing: Contributing to the seal between piston rings and cylinder walls, enhancing compression.
Corrosion Prevention: Protecting engine components from corrosion caused by combustion byproducts and moisture.

Over time, oil degrades and becomes contaminated, losing its ability to perform these functions effectively. Regular oil changes are essential to maintain optimal engine health.

Materials and Tools Required

Gather the following materials and tools before starting the oil change:

New Engine Oil: The 2015 Murano typically requires 5.1 quarts (4.8 liters) of 5W-30 engine oil. Always consult your owner's manual for the exact specification. Using the correct viscosity and specification (API rating) is vital for proper engine operation.
New Oil Filter: A high-quality oil filter, such as a Nissan OEM filter or a reputable aftermarket brand like Mobil 1 or Purolator, is crucial. Ensure it's the correct filter for your specific engine.
Oil Filter Wrench: A cap-type or strap-type wrench designed for removing and installing oil filters.
Socket Wrench Set: Including sockets for removing the drain plug (typically 14mm or 19mm; confirm before starting).
Drain Pan: A container to collect the used oil. Choose one with sufficient capacity (at least 6 quarts).
Funnel: For pouring new oil into the engine without spillage.
Rags or Shop Towels: For cleaning up spills and wiping down components.
Jack and Jack Stands: To safely raise the vehicle and provide adequate working space. Never work under a vehicle supported only by a jack.
Wheel Chocks: To prevent the vehicle from rolling.
Torque Wrench: To properly tighten the drain plug and oil filter to the specified torque.
Gloves: To protect your hands from oil and grime.
Safety Glasses: To protect your eyes from splashes.
Owner's Manual: For specific instructions and torque specifications for your vehicle.

Step-by-Step Procedure

Preparation: Park the Murano on a level surface. Apply the parking brake and use wheel chocks behind the rear wheels. Warm up the engine for a few minutes to make the oil flow more easily. However, be careful not to overheat it, as hot oil can cause burns.
Raising the Vehicle: Loosen the drain plug slightly before lifting the vehicle. This can sometimes be easier to do when the car is on the ground. Position the jack under the designated jacking point (refer to your owner's manual). Raise the vehicle to a suitable height and securely support it with jack stands placed under the vehicle's frame rails. Ensure the jack stands are properly positioned and locked.
Locating and Removing the Drain Plug: Locate the oil pan underneath the engine. The drain plug is typically a large bolt at the bottom of the pan. Position the drain pan directly beneath the drain plug. Using the correct size socket wrench, carefully remove the drain plug. Be prepared for the oil to flow out quickly. Allow the oil to drain completely, which may take 15-20 minutes.
Removing the Oil Filter: While the oil is draining, locate the oil filter. On the 2015 Murano, it's typically accessible from underneath the vehicle, but its exact location may vary slightly depending on the specific model year. Use the oil filter wrench to loosen the old oil filter. Place a rag or shop towel underneath the filter to catch any oil that spills. Once loosened, unscrew the filter by hand. Be prepared for some oil to spill out.
Preparing and Installing the New Oil Filter: Lightly lubricate the rubber gasket on the new oil filter with clean engine oil. This helps ensure a proper seal. Screw the new oil filter onto the engine by hand until the gasket makes contact with the engine block. Then, tighten it an additional 1/2 to 3/4 turn, or according to the instructions on the filter. Do not overtighten the oil filter.
Reinstalling the Drain Plug: Once the oil has completely drained, clean the drain plug and inspect the sealing washer (if equipped). If the washer is damaged, replace it. Reinstall the drain plug by hand, then tighten it to the manufacturer's specified torque using a torque wrench (typically around 25-30 ft-lbs). Overtightening can damage the oil pan.
Adding New Oil: Locate the oil fill cap on top of the engine. Remove the cap and insert a funnel. Pour in the specified amount of new engine oil (approximately 5.1 quarts). Consult your owner's manual for the exact amount.
Checking the Oil Level: After adding the oil, replace the oil fill cap. Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter. Turn off the engine and wait a few minutes for the oil to settle. Remove the dipstick, wipe it clean, reinsert it fully, and then remove it again. Check the oil level. It should be between the "min" and "max" marks on the dipstick. Add more oil if necessary to reach the "max" mark.
Lowering the Vehicle: Once you're satisfied with the oil level and have checked for leaks, carefully remove the jack stands and lower the vehicle.
Resetting the Oil Life Monitoring System: The 2015 Murano has an oil life monitoring system that needs to be reset after an oil change. The procedure typically involves navigating through the vehicle's information display using the steering wheel controls. Consult your owner's manual for specific instructions on how to reset the system. This step is crucial for maintaining accurate service intervals.
Proper Disposal of Used Oil: Properly dispose of the used oil and oil filter at a recycling center or auto parts store. Do not pour used oil down the drain or into the environment.

Technical Considerations

Oil Viscosity and Specifications

Selecting the correct oil viscosity and specification is paramount. 5W-30 is generally recommended for the 2015 Murano's VQ35DE engine. The "5W" indicates the oil's viscosity at cold temperatures, while "30" represents the viscosity at operating temperature. Using the wrong viscosity can lead to increased engine wear, reduced fuel economy, and potentially engine damage. Look for oils that meet or exceed the API SN or SN PLUS specifications, indicating they meet modern engine protection standards.

Filter Design and Functionality

The oil filter plays a crucial role in removing contaminants from the oil. Most oil filters use a paper or synthetic media element to trap particles. Some filters also incorporate a bypass valve, which allows oil to flow around the filter element if it becomes clogged, preventing oil starvation. Anti-drainback valves are also common, preventing oil from draining back into the oil pan when the engine is off, ensuring quick lubrication upon startup. Opting for a high-quality filter ensures effective filtration and protects the engine from harmful particles.

Torque Specifications

Adhering to the manufacturer's specified torque for the drain plug and oil filter is essential. Overtightening the drain plug can damage the oil pan threads, leading to leaks or requiring costly repairs. Undertightening can also result in leaks. A torque wrench is a vital tool for ensuring proper tightening. Similarly, overtightening the oil filter can damage the filter housing or the engine block. Tighten the filter according to the instructions provided on the filter itself.

Synthetic vs. Conventional Oil

While conventional oil is a viable option, synthetic oil offers several advantages. Synthetic oils typically provide better lubrication, improved high-temperature performance, enhanced wear protection, and longer drain intervals. They are also more resistant to oxidation and sludge formation. While synthetic oil may be more expensive upfront, the benefits can outweigh the cost, especially for vehicles driven in demanding conditions or subjected to frequent short trips.

Analyzing Used Oil

For a more in-depth understanding of engine health, consider sending a sample of used oil to a laboratory for analysis. Oil analysis can reveal the presence of wear metals, contaminants, and other indicators of potential problems. This information can help you identify issues early and take corrective action before they lead to major engine damage. Blackstone Laboratories is a reputable company that offers oil analysis services.
