Having owned one myself, I can say that when it comes to reliability, the G35 is an excellent choice and, with proper maintenance, can retain its performance for several years. The only aspect of this amazing vehicle that does need attention is the oil.
This is because using the right oil is essential if you want to keep your car running smoothly at all times and want to avoid major expenses on repairs. But selecting the best one can be quite challenging, especially for new car owners. That’s why I decided to come up with this detailed guide on the subject.
Hi, I’m Stacy, and I’ll be telling you all about the best oil for Infiniti G35 currently available on the market right now. So, let’s jump right in!
Top Five Oils For Infiniti G35
1. Castrol Synthetic Motor Oil
Castrol is among the first brands that come to mind when talking about automotive lubricants. This British manufacturer has been in business since 1899, and this motor oil from the brand offering exceptional performance is the perfect example of how good its products are.
Product Highlights
My decision to include Castrol on this list was supported by several reasons besides the reputation of the manufacturer for delivering the best products in the industry. The primary reason is that this oil meets the minimum high temperature and high shear viscosity (HT/HS) standards that leading automobile manufacturers demand.
It ensures proper protection to the vehicle while it is in use and provides the smoothest driving experience.
Additionally, this oil has been specially formulated for unlocking the maximum performance of newer car engines and has been specially tuned for four-cylinder engines. These engines operate at higher temperatures compared to older ones and can be adversely affected by oil thickening, which often happens with oils from other brands.
However, that is not the case with the Castrol Advanced Synthetic Motor Oil, which avoids high-temperature oil thickening, helping unlock the best performance of your vehicle.
What’s There To Like About It?
The thing that I liked the most about this oil is how effectively it promotes better fuel economy. Friction can waste up to ten percent of the engine power, but the Fluid Titanium technology of the oil ensures minimum wastage, resulting in better fuel efficiency and performance.
And this impressive performance is available at a very affordable price so that you can enjoy great savings all around.
What’s There Not To Like About It?
Compared to oils from different manufacturers, the Castrol synthetic motor oil tends to get dirty more quickly. But that’s not a major issue if you frequently change the oil of your vehicle. So long as you ensure that, there won’t be any performance issues with this oil.
Pros and Cons of Castrol Synthetic Motor Oil
Pros
Cons
- Specifications established by BMW, Mercedes-Benz and Volkswagen demand that oils meet a certain minimum high temperature/high shear (HT/HS) viscosity to provide proper protection
- Diesel Application. Formulated for highly tuned four cylinder and latest technology engines that operate at higher temperatures, such as European Vehicles
- Approved and Licensed Specifications
2. Valvoline Full Synthetic Motor Oil
The next oil that I reviewed is the full synthetic motor oil from Valvoline, an American manufacturer of automobile lubricants and additives. And the main reason I recommend this oil is due to the high level of protection it offers to the engine to maintain stable performance.
Product Highlights
With over 150 years of experience in the industry, Valvoline is a brand you can count on to offer products that deliver the best user experience, like this motor oil. It contains enhanced anti-wear additives that provide better protection for the various parts of the engine, preventing it from wearing out quickly.
Another thing that I liked about this motor oil is that the manufacturer has used the best selection of base oils which ensure a smooth start even in cold weather. These base oils additionally contain superior viscosity modifiers that ensure that the oil has just the right amount of viscosity to be able to protect the engine surfaces.
I also discovered that the Valvoline synthetic motor oil contains extra detergents that prevent the accumulation of deposits on the engine surfaces. This, in turn, ensures that the engine parts continue functioning optimally so that your G35 continues delivering good performance.
What’s There To Like About It?
The feature that I really loved about the Valvoline synthetic motor oil is its resistance to cold weather. While other oils become thick, reducing the flow, this one remains almost unaffected and retains its flow even in low temperatures.
Other than that, it is transparent, making it easier to know when the oil becomes dirty and needs changing. Non-transparent oils make it quite cumbersome to determine whether they are dirty and require changing.
What’s There Not To Like About It?
The only reason why I’ve not placed this option at the top of my list is that it comes in a thin plastic container which is highly prone to rupturing. This was not a problem with the Castrol Synthetic Motor Oil, which arrived in a good quality container with minimal possibility of leakage.
Pros and Cons of Valvoline Full Synthetic Motor Oil
Pros
Cons
- ADVANCED PROTECTION AGAINST the four main causes of engine breakdown: wear friction heat and deposits
- 40% BETTER WEAR PROTECTION vs. industry standard as tested in the Sequence IVB engine test
- 25% BETTER DEPOSIT PROTECTION with superior engine cleaning detergents as tested in the GMOD engine test

Additionally, unlike other conventional motor oils, this oil keeps the pistons cleaner than even the most stringent industry standards, helping your vehicle run even smoother for longer periods. This is in addition to the sludge protection that Ultra Platinum oil offers, thanks to the detergents present in it, so your engine remains as good as new.
The manufacturer has also focused on ensuring that the oil flows faster even when temperatures are as low as -40° F. At the same time, it is protected against oxidation and degradation in extremely high temperatures, even over 400° F.
What’s There To Like About It?
Most manufacturers develop motor oils for specific brands or models only. I was delighted to find that that is not the case with the Ultra Platinum motor oil. It is suitable for a wide variety of makes and models, including cars, SUVs, light vans, and more. This makes it ideal for your Infiniti G35.
Besides the incredible performance, the price is another thing that makes this a choice worth considering. Other oils that offer a similar performance are nearly three times the price.
What’s There Not To Like About It?
The one thing that I noticed while testing this oil from Ultra Platinum is that some amount of salt tends to accumulate at the bottom of the container. That is the sole reason why this product is in the third spot, as neither the Castrol Synthetic Motor Oil nor the Valvoline Full Synthetic Motor Oil has this defect.
Pros and Cons of Ultra Platinum Full Synthetic Motor Oil
Pros
Cons
- Full synthetic 5W-20 engine oil with PurePlus Technology that is race-trusted for unbeatable engine protection*
- Pennzoil Ultra Platinum helps extend engine life and protects for up to 20 years or 750,000 miles, whichever comes first** (see warranty information in Product Description)
- No other leading motor oil provides better wear protection from friction (based on Sequence IVA wear test using SAE 5W-30)
4. Mobil Synthetic Motor Oil
Mobil is another big name in the automobile oils and lubricants industry, which is why I decided to pick this brand for the next spot. This formulation has been designed to deliver maximum performance and protection to your vehicle engine so that it continues functioning at optimal levels.
Product Highlights
For this brand, let me start with the composition of the oil. The Mobil Synthetic Oil is formulated with a proprietary blend of components to ensure maximum compatibility with Gasoline Catalytic Converters (GCC) and Diesel Particulate Filters (DPF). These components are generally present in all the latest vehicles from different manufacturers, and this oil ensures that they operate without any issues.
Then, the Mobil 1 technology provides wear resistance and protection to the engine so it can perform better for longer periods. This technology also helps reduce sludge buildup and deposits, leaving fewer phosphate blocks than other brands, keeping the engine of your G35 clean.
But, the unique feature of this motor oil is that it is one of the few options that meet the requirements of international vehicle manufacturers. In fact, many famous brands have rated this oil highly for its performance.
What’s There To Like About It?
If you’re looking for a low-SAPS oil, the Mobil Synthetic Motor Oil can be an excellent choice. This oil releases a very low amount of phosphorus and sulfated ash content, helping ensure the longevity of the DPF of your G35.
Plus, it has been designed with the latest vehicle engines in mind to ensure proper protection while meeting the highest industry standards. The Mobil 1 technology further improves the performance of your car so that you can have a worry-free driving experience.
What’s There Not To Like About It?
While I was impressed by the performance of this oil from Mobil, it may not be an ideal option for those with a small budget. The previous options, such as the Castrol Synthetic Motor Oil or the Valvoline Full Synthetic Motor Oil, might be better. Even the Ultra Platinum Full Synthetic Motor Oil is more affordable.

5. Pennzoil Full Synthetic Motor Oil
Most car owners have heard of the Pennzoil brand, which is an American motor brand oil that offers some of the best products on the market. And this motor oil from the brand, which provides better fuel economy and greater engine protection, is no exception.
Product Highlights
I chose the Pennzoil motor oil for this list as it has been specially formulated to provide unparalleled performance in extreme temperatures. Made from natural gas instead of crude, this oil flows faster in low temperatures and remains protected even in excessive heat. It also has a lower tendency to evaporate, which cannot be said for oils from other brands.
Additionally, it reduces mineral deposits on the engine that might adversely affect its performance, keeping it close to factory clean. This also ensures that the engine is protected against wear, preventing the need for frequent repairs.
Similarly, your engine is protected against loss of power as the Pennzoil synthetic motor oil neutralizes corrosive combustion acids. So, the performance of your Infiniti G35 will remain stable at all times.
The Pennzoil motor oil is another option officially recommended by various car manufacturers, making it a reliable and safe choice for your Infiniti G35.
What’s There To Like About It?
The biggest reason why I found this Pennzoil motor oil a good choice is that some of the biggest car manufacturers recommend it for their vehicles. That means that you can trust the Pennzoil product to offer reliable performance for most types of vehicles.
Apart from that, I noticed that the engine of my G35 operated more silently with this oil than with other oils. Combined with the outstanding performance and fuel economy, this is another major advantage this oil offers.
What’s There Not To Like About it?
When buying this product, keep in mind that the rebate information on the packaging is incorrect. I was disappointed to discover that I only got half of the expected amount. Again, this is not an issue with the Castrol Synthetic Motor Oil, Valvoline Full Synthetic Motor Oil, or the remaining two options.
Pros and Cons of Pennzoil Full Synthetic Motor Oil
Pros
Cons
- Nothing keeps your engine closer to factory clean
- Better fuel economy

Buyers Guide
These are my top five picks regarding the best oil for Infiniti G35 currently available on the market. While looking for these options that delivered the best performance, I had to consider several factors to ensure that only the most outstanding items were included.
In this section, I will share some of the factors that should be considered when buying motor oil. These factors will make it easier to find and select the most suitable option for your requirements.
1. The Car Manufacturer And Model
The first and perhaps the most crucial factor to consider when selecting motor oil is the brand and model of the vehicle. This will ensure that the oil you choose is compatible with your car while making it easy to find the best oil. Since only compatible options will need to be considered, both effort and time will be saved.
That said, with newer high-performance engines, oil manufacturers are coming up with newer formulations, so you do not need to worry about your choices being limited.
2. Driving Environment
The driving environment is another important factor you should consider, as it encompasses several variables itself. These include the type of climate, paved or unpaved roads, and other similar elements. Varying environmental conditions can put a strain on the vehicle in different ways. For instance, colder climates might require you to use oil that flows smoother at lower temperatures.
Similarly, driving on unpaved roads can cause greater friction and wear, which will require using oil that protects against such factors.
3. Engine Oil Type
Basically, three types of engine oils are available on the market - mineral, semi-synthetic, and synthetic. All these different oils have various pros and cons. Mineral-based oil is a heavily refined version of the oil sourced from the ground, whereas semi-synthetic oils also contain artificial additives. Synthetic oil is manufactured in factories using chemicals.
Since the base oil makes up 80-90 percent of engine oil, selecting the right type of oil is vital for getting the best performance.
4. Viscosity Grade
The viscosity grade indicates how resistant the oil is to flowing and is considered along with the climate and driving conditions when selecting the right oil. It is generally mentioned in the labeling of the product and is made up of two numbers.
These numbers inform you about the tendency of the oil to flow in different conditions, with the first number indicating low-temperature performance. The second number means how the oil flows at an average temperature.
Oils that are thinner and have low viscosity tend to flow more quickly and reach various engine parts more effectively. It is especially important in colder weather for protecting the engine. On the other hand, thicker oils with higher viscosity are better at protecting the engine at higher temperatures by maintaining a strong film over the parts.
5. Oil Standards
The labeling of engine oils from different brands contains acronyms like ACEA, API, and ILSAC. These are various standards that are established by leading businesses in the industry to ensure the proper quality of the products. Oils that have these standards mentioned on the packaging are guaranteed to provide better performance and quality.
ACEA (European Automobile Manufacturers Association) and API (American Petroleum Institute) are the most popular standards. The former determines the type of engine the oil is suitable for and its performance, while the latter additionally classifies oils based on wear protection and fuel economy.
6. Oil Additives
Manufacturers often add various types of additives to motor oil to improve their performance. These additives may include viscosity-index improvers, detergents and dispersants, anti-wear agents, and more.
Viscosity-index reduces the tendency of the oil to thin with increasing temperatures, while detergents are added to remove deposits on various engine parts that can affect performance. Similarly, dispersants disperse solid particles, preventing them from forming a sludge.
Anti-wear agents are added to oils to protect the engine parts in case the oil film breaks down due to high temperatures or other reasons. Other additives may include friction modifiers for reducing friction between various parts and pour-point depressants to keep the oil flowing even at low temperatures.
Frequently Asked Questions
The period for which motor oil remains usable depends upon certain variables, the main one being the type of oil it is. Conventional motor oil from most brands has a shelf life of about ten years, while semi-synthetic and synthetic oils can last for seven to eight years. It is best to use motor oil within two to five years of manufacturing.
Even if unopened, motor oil will degrade over time if it is not used timely but may last longer than when opened. According to most manufacturers, motor oil can offer optimum performance for up to five years.
Yes, you can mix both regular mineral oil and synthetic motor oil as they are both composed of mostly the same components. However, by mixing the two together, you will reduce the performance of the synthetic oil.
My Final Recommendation
I hope you enjoyed going through this guide and it has helped you find the best oil for Infiniti G35. Just make sure to keep in mind the essential factors while making a final decision to get the best experience.
Now it is time to conclude this guide, but before that, let me share my favorites from the list with you. The overall best option would be the Castrol Synthetic Motor Oil, which comes from a reputable brand and delivers unmatched performance.
Then there is the Valvoline Full Synthetic Motor Oil, which keeps your engine protected and ensures superb performance even at low temperatures.Â
On that note, let’s wrap things up. Until next time!
