Ultimate DIY Guide to Changing Engine Oil in Your Infiniti QX30

Changing engine oil for a Infiniti QX30 car 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.

The Infiniti QX30 is a luxury subcompact crossover that was first introduced by Infiniti, Nissan’s luxury vehicle division, back in 2016. The car has one generation and was sold in the US from 2017 to 2019. The QX30 runs on a 2.0L turbocharged inline-four engine, providing an excellent blend of power and efficiency.

Interestingly, the Infiniti QX30 is essentially a rebadged version of the Mercedes-Benz GLA-Class. This is the result of a partnership between Renault-Nissan and Daimler AG. It’s noteworthy that the car is built on the Mercedes-Benz MFA platform, which it shares with the Mercedes-Benz A-Class, B-Class, and the CLA-Class.

In terms of the naming, the Infiniti QX30 retained its name in the majority of the markets worldwide, including the US. However, in the Australian and New Zealand markets, this model was simply known as the Infiniti Q30.

What You Need to Know Before Changing Engine Oil in Your Infiniti QX30

Before you get started, you should know the type and quantity of oil your Infiniti QX30 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 in Infiniti QX30?

As a general rule, Infiniti recommends changing the oil in the QX30 every 5,000 miles or every six months, whichever comes first. However, if you frequently drive in severe conditions like heavy traffic, high heat, or on rough roads, you might want to consider changing the oil more frequently.

Step-by-Step Guide: Checking Engine Oil Level in Your Infiniti QX30

  1. Park your QX30 on level ground and turn off the engine. Wait a few minutes for the oil to settle down into the oil pan.
  2. Pop the hood and find the dipstick. In your QX30, it’s typically a bright yellow loop handle near the front of the engine.
  3. Pull the dipstick out and wipe it clean with a rag or towel.
  4. Insert the dipstick back into the tube and push it all the way in, then pull it out again. Now, you can read the oil level.
  5. Check where the oil level is. The dipstick has two marks or holes, indicating ‘Min’ and ‘Max’. If the oil level is between these two marks, it’s in a safe range. If it’s below the ‘Min’ mark, you need to add more oil. If it’s above the ‘Max’ mark, you’ve got too much oil and need to drain some.

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 for in Infiniti QX30

To check the quality of the oil, put a drop of engine oil on a clean, white piece of paper. Good oil is typically clear or slightly amber in color. If it’s dark or dirty-looking, it’s time for a change. Also, if the oil spreads quickly and thinly on the paper, it’s still in good condition. If it’s thick and doesn’t spread easily, it may be old or contaminated.

Comparing Engine Oils for Infiniti QX30: Pros and Cons of Different Types

There are three main types of engine oil: conventional, synthetic blend, and full synthetic.

  1. Conventional oil is the least expensive and works fine in many situations. However, it doesn’t offer the best protection in extreme temperatures.
  2. Synthetic blend oil is a mixture of conventional and synthetic oil. It offers better protection and performance than conventional oil but is less expensive than full synthetic.
  3. Full synthetic oil offers the best protection, especially in extreme temperatures, and improves fuel economy. However, it is the most expensive.

For the Infiniti QX30, it’s recommended to use a synthetic oil, as it gives the best protection for your turbocharged engine. Check your owner’s manual for the exact grade and specification.
