Changing engine oil for a Infiniti Q50 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 Q50 is a compact luxury car that was first introduced to the world by the Japanese automaker Infiniti in 2013. The first-generation Q50 was produced from 2013 to 2017. In 2017, Infiniti introduced the second generation, which offered more advanced technology and better performance. The Q50 has a wide range of engines, starting from a 2.0L turbocharged inline-4 to a powerful 3.5L V6 hybrid, and even a high-performance 3.0L twin-turbo V6 for the Red Sport 400 models. In the US, the car was available from 2013, replacing the Infiniti G-series sedans. Outside the US, the brand was initially known as Nissan’s luxury division, so the Q50 was referred to as Nissan Skyline in Japan and was sold under the name of Nissan Infiniti Q50 in China.

How to change Infiniti engine oil in theory
Changing the oil is critical because it keeps the engine running smoothly. It removes dirt and debris that can damage the engine and helps improve fuel economy. Regular oil changes prolong the life of your engine, saving you money on repairs in the long run.
So, let’s define the basic steps for performing a car engine oil change.
Warm up the engine to operating temperature
Drain the used engine oil and remove the old oil filter
Install a new filter and fill with fresh oil
Check the oil level with a dipstick
By following these simple steps, you can service your car. Now let’s take a closer look at each of the steps, select the recommended oil and filter. At the end of this page I will answer possible questions.
What you need to know before starting work
Frequency (interval) of engine oil change
The frequency of oil changes can depend on several factors, including how you drive, the age of your car, and the type of oil you use. However, for an Infiniti Q50, the manufacturer recommends changing the oil every 5,000 miles or every 6 months, whichever comes first. It’s important to remember that this is a guideline; if you drive in harsh conditions, you might need to change the oil more frequently.
How to check the level of engine oil
To check the level of engine oil, you first need to locate the dipstick under the hood of the Infiniti Q50. It’s usually a bright color, like yellow, and has a ring or handle at the end. Pull the dipstick out, wipe it clean with a rag or paper towel, and then push it back into the tube all the way. Pull it out again and look at the markings at the end of the stick. There should be two markings – the oil level should be between these two marks. If the oil level is below the lower mark, you need to add more oil. If it’s above the top mark, you’ve got too much oil and need to drain some out.
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 assessment of engine oil in a Infiniti Q50 engine
You can make a basic assessment of the oil condition by placing a drop of it on a clean white piece of paper. If the oil spreads out and is dark in color, it may be dirty and need changing. If it’s light, almost clear, and doesn’t spread much, it’s likely in good condition.
What can (should) be changed at the same time with engine oil
When changing the engine oil, it’s a good idea to also change:
- Oil filter
- Drain plug and washer (if worn out or damaged)
- Air filter (as needed)
- Inspect and replace coolant, brake, and transmission fluid (as per manufacturer’s recommendation).
Advantages and disadvantages of different types of engine oils
Engine oils come in different types: conventional, synthetic blend, and full synthetic. Conventional oil is the cheapest, but it doesn’t offer the best protection or fuel efficiency. Synthetic blend offers better protection and performance than conventional oil and is less expensive than full synthetic. Full synthetic oil offers the best protection and performance but is the most expensive.
For the Infiniti Q50, it’s recommended to use a full synthetic oil because it offers the best protection, performance, and fuel efficiency. It’s a bit more expensive, but considering the high-performance nature of the Q50, it’s a worthy investment to keep your Infiniti running smoothly and efficiently.

Necessary tools and conditions
To change the engine oil, you’re gonna need:
- Engine oil of the correct type and amount.
- A new oil filter.
- Oil filter wrench to remove the old oil filter.

Before starting the work, make sure the engine is warm to ensure the old oil can drain out smoothly. But be careful, as the oil could be hot. Always follow safety procedures when lifting and securing your vehicle. It’s also good to have some form of spill containment or absorbent material on hand, in case of spills or drips.
Step-by-step instruction
How to warm up the engine before changing the oil?
Warming up your engine before an oil change helps to ensure that the oil flows out of the engine more easily, carrying any particles or debris with it. The best way to warm up your engine is simply by driving your Infiniti Q50 around for about 10-15 minutes. But remember, don’t let the engine get too hot, as you could risk burning yourself when draining the oil.

Possible questions after self-service FAQ
What problems can arise after an incorrect self-changing engine oil?
If you incorrectly change your engine oil, you might face issues like leaks from not tightening the drain plug or oil filter enough. You might also cause damage to your engine if you use the wrong type of oil, don’t fill up with enough oil, or overfill.
How can I check for engine oil leaks after changing it myself?
After changing your oil, start your engine and let it run for a few minutes. Turn it off, then check underneath the car for any drops of oil. Also check the oil filter and drain plug area for any leaks.
How to reset the oil change counter?
In an Infiniti Q50, to reset the oil change light, turn the ignition to the “on” position without starting the engine. Navigate to the “Settings” menu on the infotainment system, select “Maintenance”, then “Oil and Filter”, and finally select “Reset”.
What to do with old oil after replacement?
After changing your oil, pour the old oil into a sealable container and take it to a recycling facility or auto parts store. Most places that sell motor oil also accept used oil for recycling. Never dump used motor oil in the trash, down a drain, or on the ground as it’s harmful to the environment.
