Full Guide to Changing Engine Oil in Infiniti QX56

Changing engine oil for a Infiniti QX56 can be an overwhelming task for an unprepared person, and stretch out for a whole day. Although the work can be done in just 30 minutes. I’m here to share my experience and secrets with you! Let’s start with a few words about the car.

Infiniti QX56 is a full-size SUV developed by Infiniti, a subsidiary of Nissan. The vehicle was first introduced in the U.S. market in 2004 and was initially available only in North America. The QX56 gained wide recognition for its luxurious interior, spaciousness, and hauling capabilities.

The Infiniti QX56 went through several generations, each offering its own improvements and updates. The first generation was produced from 2004 to 2010 and was equipped with a 5.6-liter V8 engine. Then, in 2011, the second generation was introduced and was produced until 2013.

The second generation also utilized a 5.6-liter V8 engine, but with enhanced power and efficiency. In 2014, Infiniti introduced the third generation of the QX56, which was renamed the Infiniti QX80.

The third generation continued to use the 5.6-liter V8 engine but also received updated exterior design and technological enhancements.

So, the Infiniti QX56 (now known as the QX80) has three generations, equipped with a 5.6-liter V8 engine, and has been available in the American market since 2004.

What you need to know before changing the motor oil

Interval for changing the motor oil

Many inexperienced car owners wonder how often they need to change the motor oil in an Infiniti QX56?Experienced Infiniti QX56 owners recommend changing the motor oil every 5,000-7,500 miles (8,000-12,000 km) or every 6 months, whichever comes first. The official recommendations for oil change intervals can be found in your vehicle’s owner’s manual. Proper oil changes help maintain optimal engine performance and extend its lifespan.

Step-by-step instructions: Checking the motor oil level in an Infiniti QX56

  1. Open the car hood and locate the engine oil dipstick. The dipstick is usually labeled “OIL” or “ENGINE OIL” and is located near the engine.
  2. Before starting the engine, ensure that the car is on a level surface and the engine has cooled down.
  3. Pull the dipstick out of its place and wipe it clean with a cloth or paper towel to remove old oil.
  4. Insert the dipstick back into the opening all the way and then pull it out again.
  5. Pay attention to the marks or lines on the dipstick. They indicate the minimum and maximum oil levels.
  6. The oil level should be between these marks. If the level is below the minimum mark, oil needs to be added. If the level is above the maximum mark, oil needs to be drained to the desired level.
  7. If you need to add oil, open the engine oil filler cap and carefully pour the oil into the filler neck, following the manufacturer’s recommendations for the volume and type of oil.
  8. After adding oil, recheck the level using the dipstick to ensure it is within the acceptable range.

Visual inspection of the motor oil: What to check

A visual inspection of the motor oil can provide an idea of its current quality. Here’s a simple way to check using a sheet of paper and a drop of oil:

  1. Prepare a clean white sheet of paper.
  2. Remove the dipstick for oil checking and drop a small amount of oil onto the paper.
  3. Pay attention to the following aspects:
    • Color: New oil should be transparent or light yellow. If the oil appears dark or dirty, it may indicate contamination or aging.
    • Consistency: The oil should be smooth and uniform. If you notice any thick or lumpy substances, it could be a sign of an engine problem.
    • Odor: Fresh oil usually has a distinctive smell. If the oil has a strange or bitter odor, it may indicate impurities or engine issues.

It’s important to remember that visual assessment of oil is not a precise method and does not replace regular oil changes and checks as recommended by the manufacturer.

Additional maintenance tasks when changing the motor oil in an Infiniti QX56

When changing the motor oil in an Infiniti QX56, it is also recommended to perform the following additional tasks:

  • Oil filter: Install a new oil filter along with the oil change.
  • Check and replace the drain plug gasket: The drain plug gasket prevents oil leakage. If there are signs of deformation on the gasket, replacement is necessary.
  • Check and, if necessary, replace the cabin air filter.

Comparison of motor oils: Advantages and disadvantages of different types

When choosing a motor oil for an Infiniti QX56, you can consider the following types of oils and their characteristics:

  1. Synthetic oil:
    • Advantages: Offers high stability at high temperatures, excellent lubricating properties, improved wear protection, and longer change intervals.

  2. Semi-synthetic oil:
    • Advantages: Combines the benefits of synthetic and mineral oils. Provides good protection and moderate pricing.
    • Disadvantages: May be less effective under extreme usage conditions.
