The Infiniti QX50 is a luxury compact crossover SUV that was first introduced by Infiniti, the luxury division of Nissan, in 2007. The car has undergone several generations and updates since its initial release. The first generation of the Infiniti QX50, which was known as the Infiniti EX, was produced from 2007 to 2013. It featured a range of gasoline engines, including a V6 and a turbocharged inline-four.

In 2014, the second generation of the QX50 was introduced, and the car was renamed from Infiniti EX to Infiniti QX50 to align with Infiniti’s new naming conventions. The second-generation QX50 featured a longer wheelbase and a more spacious interior compared to its predecessor. It was powered by a 3.7-liter V6 engine.

In 2018, the third generation of the Infiniti QX50 was launched. This generation introduced a completely redesigned QX50 with a more modern and aerodynamic look. It featured a new variable compression turbocharged engine, which aimed to provide a balance between power and fuel efficiency.

The Infiniti QX50 has been sold on the US market since its initial release in 2007. The car has gained popularity among luxury SUV enthusiasts due to its stylish design, comfortable interior, and advanced features.

What You Need to Know Before Changing Engine Oil

Before you get started, you should know the type and quantity of oil your Infiniti QX50 requires. Your owner’s manual will provide this information. Additionally, you’ll need some basic tools like an oil filter wrench, a drain pan, a funnel, and perhaps some gloves. Remember, safety first. Always make sure the car has cooled down before you start changing the oil to avoid burns.

How often should you change engine oil

Owners of the Infiniti QX50 typically change the engine oil every 5,000 to 7,500 miles or every 6 to 12 months, whichever comes first. However, it is essential to consult the owner’s manual for the specific oil change interval recommended by the manufacturer. The recommended interval may vary depending on factors such as driving conditions, climate, and oil type used.

Step-by-Step Guide: Checking Engine Oil Level in the Infiniti QX50

  1. Park the car on a level surface and turn off the engine. Allow the engine to cool for a few minutes.
  2. Open the hood of the car and locate the engine oil dipstick. It is usually labeled with a bright-colored handle or marked with the word “Engine Oil.”
  3. Pull the dipstick out of the engine and wipe it clean with a cloth or paper towel. Make sure there are no oil drips or debris on the dipstick.
  4. Reinsert the dipstick fully into the dipstick tube. Push it all the way in to ensure an accurate reading.
  5. Pull the dipstick out again and observe the oil level. The dipstick usually has two marks indicating the acceptable range. The oil level should be between these marks. If the oil level is below the lower mark, it is too low, and additional oil should be added. If the oil level is above the upper mark, it is too high, and some oil should be drained.
  6. If the oil level is too low, add the recommended type and amount of engine oil through the oil filler cap. Recheck the oil level using the dipstick until it falls within the acceptable range.
  7. If the oil level is too high, you will need to drain some of the excess oil. Follow the oil draining process outlined in the simple plan to remove the excess oil until the level is within the acceptable range.

A study conducted by General Motors (GM) in 1974 showed that lengthening the engine oil-change interval could reduce the frequency of automotive maintenance, the amount of oil required to service the car population, and the potential pollution problem resulting from the disposal of used oil.

Visual Inspection of Engine Oil: What to Look

To get a rough idea of the quality of the engine oil in the Infiniti QX50, you can perform a simple visual inspection using a sheet of white paper and a drop of oil. Here’s how:

  1. Place a clean sheet of white paper on a flat surface.
  2. Collect a small sample of engine oil by using a dipstick or other means.
  3. Carefully drop a small amount of the oil onto the center of the white paper.
  4. Observe the oil drop for any visible signs of contaminants or impurities. These may include dark particles, metal flakes, or milky discoloration.
  5. Additionally, check the consistency and color of the oil drop. Fresh, high-quality oil should have a clear and amber color. If the oil appears excessively dark, thick, or has a burnt smell, it may be an indication of poor oil condition.

It is important to note that this method provides a general indication of oil quality, but for a more accurate assessment, a professional oil analysis is recommended.

Additional Maintenance Tasks When Changing Engine Oil in the Infiniti QX50

When changing the engine oil in the Infiniti QX50, it is also advisable to perform the following maintenance tasks:

  1. Replace the oil filter: The oil filter should be replaced with every oil change to ensure optimal filtration and prevent contaminants from circulating in the engine.
  2. Inspect the drain plug: Check the drain plug for any damage or worn-out threads. Replace the drain plug washer or O-ring if necessary to prevent oil leaks.
  3. Replace the drain plug ring: If the drain plug ring shows signs of wear or damage, it is recommended to replace it to maintain a proper seal and prevent oil leaks.
  4. Check other fluid levels: Take the opportunity to check other fluid levels, such as coolant, brake fluid, power steering fluid, and windshield washer fluid. Top them up if needed.

Comparing Engine Oils: Pros and Cons of Different Types

When selecting engine oil for the Infiniti QX50, it is essential to consider the manufacturer’s recommendations outlined in the owner’s manual. Different types of engine oils have their strengths and weaknesses. Here are a few common types:

  1. Conventional oil: Conventional oil is the standard type of oil commonly used in engines. It offers good lubrication and protection for the engine. However, it may break down more quickly under high temperatures and may require more frequent oil changes.
  2. Synthetic oil: Synthetic oil is formulated for enhanced performance and durability. It provides better protection against engine wear, performs well under extreme temperatures, and offers longer oil change intervals. However, synthetic oil can be more expensive than conventional oil.
  3. Synthetic blend oil: Synthetic blend oil combines conventional and synthetic oils. It offers some benefits of synthetic oil, such as improved performance and extended oil change intervals, while being more affordable than full synthetic oil.

For the Infiniti QX50, synthetic oil is generally recommended by the manufacturer due to its superior performance and longevity. It provides optimal protection for the engine, especially considering the turbocharged engines in some QX50 models. However, it is crucial to refer to the owner’s manual for the specific viscosity and grade of synthetic oil recommended for the vehicle.
