Things to Consider While Picking Best Oil for Infiniti g37

Picking the right oil type for your car engine will be a daunting task. But it will help to improve your overall engine performance by protecting your engine from sludge, wear, and deposits. The following criteria will help you get the right oil to protect your engine in every driving condition. 

Check Car Model & Year

Before pouring oil into your car, ensure you get the right type of oil based on your car model. Modern car engines are compact and designed to enhance efficiency, and a new formulation of oil will keep up with those upgrades. So, take the car make & model into consideration before choosing the engine oil. 

Consider the Types of Engine Oil

Next, pick the right type of engine oil. You can find different types of engine oil including mineral oil and synthetic oil. Each of the oil types has upsides and downsides. 

For example, mineral oil is affordable and keeps your engine parts lubed. But this oil type contains impurities that may build sludge and deposits into the engine compartment. 

On the other hand, synthetic oil is a little bit pricey but delivers superior engine protection. We recommend you go with synthetic oil for the long-term benefits. 


If you ever look at the oil package, you can find confusing letters and numbers that read like W-40. The letter W stands for Winter. It indicates how oil will flow throughout your engine compartment when it is cold. And the numbers next to the letter will define how the oil will flow at operating temperature. 

Low viscosity oil is a bit thinner and runnier, which is excellent for protecting your engine at cold temperatures. On the other hand, thick and high viscosity oil delivers optimum engine protection at higher temperatures. 

Oil Standards

The simple way to measure the quality of engine oil is to take a look at its standard. If you ever read the package information, you can find acronyms like API, ACEA, SAE, and ILSAC. It means the oil you choose to buy meets or exceeds the requirements set by these organizations. 

Driving Style

Multiple short trips and long-distance drives are two types of driving styles. 

Short trips around your town require frequent start & go which puts so much stress on the engine. In the worst, it may damage your car engine by forming dirt deposits. 

Regarding this, you should pick the oil that lubes every part of the engine to protect it. We recommend you choose the synthetic oil change. 

3 Things to Happen If you Don’t Change Oil Regularly

Every car manufacturer recommends you change the engine oil when you hit a specific number of miles. Oil will keep your engine parts well-lubed, protect your engine from wear, and improve fuel efficiency. The following damages will occur to your car engine if you don’t change the oil regularly. 

Engine Wear

The engine of your vehicle consists of multiple moving parts like pistons and valves. The oil keeps those parts well-lubricated and reduces friction between those moving parts.

If the oil change interval gets delayed, the oil remaining in your engine can’t lube those moving parts. Consequently, metal-to-metal friction will increase and create engine wear. 

Make Your Engine Hot

The coolant system is not enough to keep your engine cool. Oil is a must to make your car engine cool as it can reach those areas where the coolant system can’t. When the oil change interval gets longer than recommended, oil becomes thicker because of the high temperature.

Consequently, the oil loses its ability to absorb heat, causing the engine to overheat.  Therefore, the internal parts of the engine will wear out because of the higher temperatures. 

Reduce Engine Life

An irregular oil change will be responsible for wearing out your car engine. Therefore, contaminants, dirt, and debris will build in the engine compartment to make the engine harder to function. All of these put a lot of pressure on your car engine, which reduces the engine life. 

Infiniti g35 & g37 Oil Change

You learned what damages will occur to your engine if you don’t change the oil regularly. Now, it’s time to know when you should change the engine oil to your Infiniti G37. 

Infinity suggests changing the oil twice a year if you drive your car 7500-10000 miles. In other words, you need to go for Infiniti oil change when you hit the 3k miles. 

Now, let’s know how much oil each Infiniti G35 & G37 series can hold and what type of engine oils they need.

Infiniti g35 & g37 Automatic Transmission Fluid Change

When to Change g35 & g37 Oil Filter?

If you own the Infiniti G35 and want to prolong its engine life, change the engine oil and filter timely. You should change the oil and oil filter every three months or 3000 miles.

On the other hand, you should change the oil and oil filter every 7000 miles if you own the G37. 

When to Change g35 & g37 Air Filter?

If you have an Infiniti G35 Sedan, you should change the air filter every 15000 miles to let the engine perform smoothly. On the other hand, it would be best if you change the air filter every 12000-15000 miles of your Infiniti G37.

However, we recommend you check the car manuals and change the air filter according to their guideline. 

How to Fix Low Oil Pressure on g35 & g37

Whether you own G35 or G37, low oil pressure is a common issue you may encounter. Low oil pressure may occur due to a faulty or broken oil filter. Regarding this, replacing the oil filter with a new one will fix the problem.

Using the wrong viscosity oil is another reason behind low oil pressure. To solve this issue, try to use the full synthetic oil with the correct viscosity recommended by your car manual. 

G35 & G37 Cold Air Intake Install

Installing a cold air intake on your G35 or G37 will be a bit challenging. If you don’t have any prior air intake installation experience, we recommend you go to your nearby car shop or a car mechanic to do this stuff for you.
