1. Castrol GTX UltraClean Oil
As expected, topping the list is a product by Castrol. The brand has taken the first spot on many of my lists because of how crazy awesome their oil products are.
Their Edge and Magnatec series are excellent offerings. This GTX UltraClean Oil is yet another marvel of their engineering.
The oil implements the company’s TriShield technology. This technology enables it to protect the engine from deposit formation.
For those who don’t know, deposits form in the pipelines and reduce the flow of oil.
This, in turn, reduces the engine’s performance as it cannot produce the appropriate amount of horsepower.
You may observe that by noticing if your engine takes longer to accelerate. Well, you won’t have to worry about all that anymore with this one.
The Double Action formula also eliminates the present sludge, making sure that the engine is in top-notch condition all the time.
The sludge protection on this product is so effective that it is 50% better than the toughest industry standards. Moreover, the oil also works perfectly under intense conditions.
The common problem with most products on the market is that they break down when the temperature conditions get hot. This one can resist those temperatures with ease.
Castrol is even generous enough to mention the best oil filter to be used for their oil. They recommend Bosch oil filters because they are the most effective ones on the market.
Bosch is another major player in the automotive industry. Their oil filter is the perfect match for this oil, which is designed to extend your engine’s life.
- TriShield technology prevents deposit formation
- Double Action Formula removes sludge
- Can work in extreme conditions
- Recommends Bosch filter to be used with it
- None
Castrol has done it yet again with an oil that is perfect for the Infinity G35. It should be on the top of your consideration list as there is nothing that can defeat it.
2. Schaeffer Manufacturing Co, Supreme 9000 Full Synthetic Motor Oil
I must admit that I have never heard about this brand before. But Shaeffer has been able to impress more than 400 people.
The oil checks most boxes which should be found on a high-end product. Shaeffer states, “It’s like a new car smell for engine performance.”
This is quite a bold statement. But this Supreme 9000 Full Synthetic Motor Oil does do exactly what is advertised.
The first feature I want to talk about is the oil’s performance in cold conditions. Many oil products struggle to work optimally in low-temperature conditions.
This oil, on the other hand, flows easily and does not thicken. As a result, you never have to worry about your engine getting damaged in cold conditions.
It is rare to see an oil change resulting in improved fuel efficiency. But this Schaeffer oil allows you to do that too.
This has been proven by routine testing every year, which clearly shows that this one gives you real savings.
This product, just like the previous one, protects the engine from deposits and sludge. But, unfortunately, both of them affect the engine’s ability to perform efficiently.
This results in reduced performance and higher fuel consumption. This one solves that issue too.
Overall, this oil reduces friction by a huge amount. This ensures that the engine won’t have to work harder to overcome energy loss due to that friction.
This also reduces wear on the engine, extending its lifespan. It also reduces oxidation which has a high chance of occurring at high temperatures.
Rusting affects the ability of the oil to work properly. Hence control allows you to kill two birds with one stone.
The most probable reason is that they received faulty products.
- Works flawlessly in low temperatures
- Improved fuel efficiency
- Reduced friction
- Reduced chance of rusting
- It burns through very quickly
- Not that effective
Schaeffer has created a very good product. If only they would improve their quality control, this product would have easily landed on the first spot in this article.
3. Mobil 1 5W-30 ESP Synthetic Motor Oil
Here comes another product from a world-renowned brand. Mobil 1 has appeared on several of my lists before.
Although they could not score the top place, they still provide decent products that have been a source of satisfaction for users.
This 5W-30 ESP Synthetic Motor Oil has been specifically designed for users that want to extend the lifespan of their vehicle’s engine.
It not only does that but also reduces the fuel efficiency of the vehicle. The most attractive feature is that this oil can be used on both diesel and gasoline-powered engines.
It also meets all industry requirements, which are standard for all newer design vehicles. So, you don’t have to worry about that.
The oil has two main features, as I stated above. First, it improves the engine’s health; it also helps reduce emissions, which means that you lessen your contribution to air pollution.
Second, the common issue of catalytic converters is that they have poisonous fumes. This one reduces them too.
If oil claims to be the one to buy to improve engine health, it should perform extraordinarily in the deposit department. Fortunately for you, this product does that.
The slow and reduced deposit and sludge formation mean that you won’t ever have to worry about the engine throttling. The oil also ages slowly, which extends the drain interval.
Furthermore, the manufacturer also claims that this one allows users to save fuel. Although the difference may not be that noticeable, it is still better than nothing.
The company even includes a limited warranty that ensures that if the oil damages the engine, then those repairs will be paid for by the brand itself.
- Extended drain intervals
- Reduced chance of deposit and sludge formation
- Limited warranty
- Reduced emissions
- Leaking bottles
- Missing bottles
There is no doubt that Mobil 1 has created a stunning product.
If only they would have improved their shipping standards, it would have been close to perfect for you Infinity G35 buyers.
4. Pennzoil Ultra Platinum Full Synthetic Motor Oil
Coming in fourth place is another excellent product from the brand Pennzoil.
If you are looking for a product based solely on ratings, this Pennzoil Synthetic Motor Oil is the one to go for.
With over 6000 satisfied buyers, this oil is a must on your list of consideration. Pennzoil fascinates me because their oil products are made from gasoline and not crude oil.
All other brands create oils from crude oil. However, Pennzoil is the only one that uses gasoline. This automatically makes their products one of the cleanest ones on the market.
Being one of the cleanest oils on the market always has some positive things.
One of those is that this one has the best wear protection than any other product on the market. This is not just a claim by the brand.
It has been proven using the Sequence IVA test. It also helps in fuel economy. This product will save you around 550 miles of fuel on an annual basis. That is quite a lot, in my opinion.
It also provides you with excellent protection from sludge. Sludge hardens over time and starts to form deposits.
These deposits make the engine throttle, and you don’t get to experience its full might. That will not be an issue for you any longer.
The oil can also handle extreme levels of temperature. On the plus side, it can easily work in temperature conditions that reach 400-degrees Fahrenheit.
On the opposite side, it can work flawlessly at temperatures as low as -40-degrees Fahrenheit.
One buyer received a product that was so old that it had silt collecting on the bottom. Pennzoil should not deliver older stock as its effectiveness has been reduced over time.
- Gasoline based
- 550 miles of fuel savings annually
- Can handle extreme temperatures
- Best in class wear protection
- Old stock
Out of 6000 people, few received items that had been sitting on the shelf for quite a long time.
Such oils are useless, and it is frustrating to receive them. Pennzoil should make sure to discard these units so buyers don’t have any issues.
5. Valvoline Advanced Full Synthetic 5W-30 Oil
Easily beating the number of ratings of Pennzoil by almost double is this Synthetic Motor Oil by the Brand Valvoline.
This brand commonly earns one of the top spots on my article, but this time the competition was quite strong. Nevertheless, I still did not doubt that they would earn a place on this article.
Even if Valvoline earned the last space, it is certainly not the least. It must be kept in mind that these five oils are better than hundreds of others on the market.
Synthetic oil is better than all other alternatives on the market, whether it is a conventional one or a blend.
For example, the anti-wear additives used in this oil are so effective that they surpass the wear protection requirements by 50%.
This means that you are getting better than the recommended wear reduction. The oil is also suited to work in all sorts of temperature conditions.
So, whether you live in the cold or use the vehicle for extended periods, which raises the temperature, you can rest assured that this one will not have any issues.
Its low viscosity allows it to flow easily in the winters. In addition, the temperature resistance allows it to not have a breakdown, which is a common problem in oils from other brands.
Valvoline has been manufacturing oils in the USA since 1920.
Their factory is based in Kentucky, USA, meaning that you won’t ever have to worry about receiving a poor-quality product.
The highest level of quality control ensures that there will little to no faulty products that leave the building.
This is to be blamed on the company’s shipping methods. They need to improve them.
- 50% better wear protection
- Can work in all temperature conditions
- Made in the USA
- Leaking bottles
Although Valvoline has created a great product, there is no doubt that they have to improve their shipping standards, or else buyers won’t be able to experience it.
Frequently Asked Questions
Q1. How Much Oil Does An Infiniti G35 Require?
I say this sentence in all of my guides. No matter the brand of car you own, the engine’s oil capacity should be imprinted in your brain.
Why is this important?
This is to make sure you order the correct quantity of oil. If you order extra bottles, they will be sitting on the shelves for a long time, reducing their effectiveness.
Regardless, to answer your question, the G35 needs 5.4 quarts of oil for working properly.
Q2. How Often Does Infiniti G35 Need An Oil Change?
If you use synthetic oil, you can expect a longer drain interval when compared to conventional oils.
For example, the Infinity G35 can last around 7500 to 10000 miles for a drain interval. Talking in periods, you can expect to change the oil twice every year.
Now, this depends on how much you drive your car. Some extensive drivers may even have to go through this process thrice a year.
But if you want to preserve the health of your engine, then I would recommend that you change the oil to around 5000 miles.
The oils can last for longer, but their effectiveness can be severely reduced.
Q3. What Is SAE Oil?
This is a brilliant way of grading different types of oils bases on their viscosity. SAE means Society of Automotive Engineering.
First, the viscosity is checked out by how long it takes oil to flow through a container. All of this is done at a specific temperature.
Then the oil is graded with numbers such as the 5W-30 or 0W-20, which is the number found on oil bottle. It clarifies which type of oil it is.
Q4. Is Full Synthetic Oil Worth It?
Although synthetic oil is pricier than conventional oil, that price increase gives you a whole load of benefits. You get better protection, thanks to the cleaner base oils used in it.
The wear protection is incomparable. The engine life is improved considerably when using it with conventional oil.
You are also getting better performance in reduced emissions, efficient combustion, and sometimes better fuel consumption.
Summing this up, synthetic oil is worth it and is better than blends or conventional oils.
Q5. Can I Mix Synthetic And Regular Oil For My Infiniti G35?
The answer lies in between yes and no. To be clear, you can do that. But the effectiveness of both oils will be degraded severely.
You will notice worse engine performance when comparing it to using the oils individually. Mixing oils should only be done if you don’t have any other choice.
For example, you are in the middle of an oil fill, and the quantity is less than the vehicle’s requirements.
Now you can’t drive the car for new oil and cannot wait to get delivered. In instances similar to those, you might mix oils.
Conclusion
Still need time to think?
You can have all the time you want.
I can assure you that every single one of these oils has been designed to boost your engine’s performance and take it to a whole new level when it comes to best oil for Infinity G35.
If you want a recommendation, then I would, without any hesitation, recommend the Castrol UltraClean Oil for your Infinity G35.

You can choose that or the last one, what I can assure you that there are no better products than this one available on the market.
