1. Castrol 03081 Edge Full Synthetic Motor Oil
Arriving in first, as expected, is a Product by Castrol. The brand has been making high-quality products for quite some time now, and they never fail to disappoint. Their oils are designed to keep the engine in perfect shape and also improve the vehicle’s performance. This 03081 aims the same thing.
Available in four different options, this one has different formulas. You can choose from high mileage, synthetic, advanced synthetic, and extended performance options. We will be focusing on the last option as it is the most popular one.
Being fully synthetic oil, it is the purest form of oil. The combination of high-quality base oils makes sure that you are getting a no-compromise experience.
It also has less viscosity which means that it is suitable for use in low-temperature environments. As a result, you won’t have any cold start issues, which is the problem with most oils on the market.
The oil has Castrol’s Fluid Titanium technology which allows the engine to use its maximum capacity. This technology will be appreciated by those who like to push their vehicle to their limits. It protects the oil from creating sludge and reduces wear too. This oil has been designed to withstand extreme temperature conditions.
It can withstand ten times more temperatures than the latest industry standard. In addition, the wear protection is six times better than the requirements of the Sequence IVA test. Now that is truly impressive.
Moreover, the Castrol Edge also prevents metal-on-metal contact, which reduces friction. Friction directly affects the engine’s performance. You won’t have to worry about that anymore if you choose to buy this one.
- Fluid Titanium Technology
- Six times better wear protection
- Ten times better temperature resistance
- It can be used in low-temperature environments
Castrol has created a superior product that trumps all others on the market, including the ones on this article. It is the excellent oil you can buy if you have a Jeep with a 4.0 engine.
2. Pennzoil Platinum Full Synthetic Motor Oil
With over 800 positive ratings, taking the second spot is the Full Synthetic Motor Oil from Pennzoil’s Brand. This is another highly popular brand whose products I have written upon before.
This one is another synthetic product on this list, which is unique when comparing it to other products on the market. Let’s take a closer look.
What makes this oil unique is that it is made up of natural gas and not crude oil. Crude oil-based products are everywhere globally, but there are no brands offering alternatives except for Pennzoil.
Being derived from cleaner raw materials, it consists of the company’s patented gas-to-liquid PurePlus technology. It allows you to save fuel, which is around 550 miles on an annual basis. That is impressive.
The oil also provides you with the best-in-class wear protection. According to the Sequence IVA test, this one tops all other offerings from different brands. This makes it the perfect product to recommend if you are looking for longer engine life.
Moreover, the oil also works in extreme temperature environments. You will get easy oil flow when starting in cold weather and no breakdown when the engine is used for extended periods.
Overall, the oil gives you excellent performance in all regards. You will be able to utilize your engine fully as it prevents the formation of deposits. Those who don’t know deposits form in the pipelines, which restrict oil flow, making it impossible for the engine to produce full horsepower. You don’t have to worry about that anymore.
- Made from natural gas
- Less chance of deposit formation
- Can work in extreme temperature environments
- 550 miles of fuel-saving annually
Pennzoil has created an excellent product that came close to toppling Castrol from first place. It will surely keep your engine clean and healthy if you choose to use it with your vehicle.
3. Valvoline Advanced Full Synthetic 5W-30 Oil
Here comes another product from an extremely popular brand, Valvoline. Their products have made it onto almost every single list in which I narrowed down the excellent oil for various vehicles. In addition, it has an extremely high number of ratings, which exceed the number 11000.
So, if you are looking for oil that people have extensively tested, I don’t think there is any other suitable product than this Synthetic 5W-30 Oil by Valvoline. This one has been designed for vehicles that are used and pushed to their limits.
This includes vehicles that are used for towing and those that are driven in extreme temperatures. It improves performance and many other aspects of your engine, which I will be detailing right now.
What are the main causes of engine failure? Heat, wear, friction, and deposit formation. Some of these are linked to one another. So you need a product dedicated to fixing them. This is where Valvoline steps in.
Their additives are designed to reduce wear by 40% more than the standard requirement. This boosts the lifespan of the engine.
Being fully synthetic oil, this one provides you with better heat protection than traditional oils and even synthetic blends. In addition, it can work perfectly in environments that are ten times better than industry requirements.
Even the sludge and deposit control of this oil is next level. Valvoline has gone up and beyond and has made this one 25% better than the required amount to ensure your engine won’t have any throttling issues. You will never have to worry about constrained horsepower if this product is flowing through your engine.
- 40% better wear protection
- 25% better sludge and despot control
- Can work in extreme temperatures
- Designed for heavy-duty use
- Leaking when arrived
Valvoline has to fix its product’s shipping issues, or buying this one becomes a risk for anyone who orders online. However, if you do receive an intact bottle, you will certainly be satisfied with its performance.
4. Mobil 1 High Mileage Motor Oil
Many buyers look for oils that will last them a very long time. Unfortunately, most products focus on performance more than they do on extended drain times.
This Mobil 1 High Mileage Oil is not one of those products. It has been designed to give you long drain intervals and judge by the six thousand ratings of this product; it looks like they accomplished their task.
Designed for vehicles that have traveled for over 75000 miles, one change can last for up to 10000 miles. This is why oil is so popular. In addition, you won’t have to worry about changing the oil for at least a year, given that you don’t drive too excessively.
Most oil burnt is at the LSPI stage, or more commonly known as low-speed pre-ignition. This product reduces that by quite a lot, giving more oil to the engine for proper working. It also keeps your engine clean in the process, giving you two benefits instead of one, better engine life and longer durations between changes.
Talking about extremes, this oil can tackle that at both ends. I know that the engine can get quite hot. But will it ever reach the 500-degree mark? Well, that is the upper limit of the temperature tolerance of this one.
So you won’t have to worry about oil breakdown in cases of high temperatures. On the other end, this product can work flawlessly at up to -40-degrees, making it perfect for people who drive in cold environments.
- Can handle extreme temperatures
- Reduced consumption at LSPI
- Extended drain intervals
- Excellent cleanliness
- Leaking containers
If only the company packed their products better, this oil would have easily earned a better spot on this article. However, performance-wise it is excellent for everyday use.
5. Royal Purple 51530 High-Performance Motor Oil
Finally arriving in fifth place is the High-Performance Oil by Royal Purple. This brand has taken the world by storm several times during several of its product launches. They have always been able to create outstanding products that impress buyers and reviewers alike.
Being high-performance oil, this one keeps the engine healthy first. Next, it provides you with excellent wear protection. This is possible using their additive technology, which prevents metal-to-metal contact.
The technology prevents wear far more than the required amount of both the GM dexos1 and the ILSAC GF-6 specs.
The oil also reduces friction by a great amount. A low coefficient of friction means that the engine won’t have to work that harder to produce the required horsepower.
This means a lower RPM and better fuel efficiency. Being 5W-30 oil, it meets the fuel efficiency specs of a 5W-20 one. If you don’t find that impressive, I don’t know what will.
As expected from a big brand like Royal Purple, their products undergo extreme amounts of testing. And guess what, there was not even one single instance of rusting during these extensive tests.
This means that the oil will reduce the chance of your engine oxidizing to zero. This will greatly extend your engine’s life and will also keep your oil free from contaminants.
Moreover, the oil is the only one that mentions control of exhaust emissions. The anti-wear technology, which is also patented, reduces the harmful gases produced by the engine. I don’t know about you, but reducing my impact on the environment would certainly make me feel good.
- Excellent fuel efficiency
- Patented anti-wear additives
- Reduced exhaust emissions
- No rusting
- Less oil than the advertised amount
Although Royal Purple has created an excellent product, they really should not advertise the false amount of oil. This leads to frustration for the consumer.
I noticed several questions which Jeep owners asked. Some of those questions were quite critical, and I feel obligated to inform you with the answer. Therefore, this brief but detailed FAQ will focus on those questions alongside a few basic ones. I hope your confusion will be solved after reading it. Let’s begin.
How Much Oil Does A Jeep 4.0 Take?
Starting with a basic and important question, whose answer every vehicle owner should know by heart. The 4.0 takes in six quarts of oil. You can order accordingly to ensure you are buying the correct amount. No one would want the incorrect number of bottles delivered to them.
How Do I Add Oil To My Jeep 4.0?
I saw this question asked many times, and I said to myself, why not? Therefore, I will be concisely writing the steps.
Note: The method of adding oil to your vehicle is the same for almost all vehicles. Given that you have removed the old oil, the process is quite straightforward.
First of all, gather your bottles. They are probably in one box, so grab that box, open it and get ready to rumble.
Next, open the hood, and locate the oil cap. If you don’t know what that is, it is a black cap with yellow text. It is easily distinguishable from other engine parts. Next, add the oil from where you removed the cap.
Although the amount will probably be precise, make sure not to overflow the oil. No one wants oil dripping throughout their engine. Plus, it is also a fire hazard.
So, it is probably best to avoid overflowing. Then screw the cap back on, making sure it is on tightly, and you are good to go!
That’s it; the process is simple and easy. You shouldn’t have any problems. If you have chosen oil from the above list, you will certainly have an amazing driving experience.
Which Oil Does Jeep Recommend?
So, you want to go for a recommended brand? I understand that you don’t want to risk it with other brands. The company that Jeep endorses is Pennzoil.
Pennzoil synthetic oil is recommended in all their vehicles. It did earn the second spot on this article, which automatically makes it an excellent product.
But I would still recommend the Castrol oil as it is better suited to handle all kinds of harsh treatments. Regardless, even if you choose Pennzoil, you will find that it will easily exceed your expectations.
Can I Mix Synthetic And Regular Oil?
Yes, you can. But it is not recommended. Thousands of people worldwide adopt this practice as this way they can save oil. You should only do this if you are running short on oil.
Mixing two oils, no matter the quality reduces the effectiveness of both products. I would recommend that you steer clear from this way if you want the maximum performance from your engine.
How Often Should I Change The Oil On My Jeep 4.0?
This answer solely depends on your driving habits. If you are one to drive your Jeep very frequently, it is advisable to change the oil to around 5000 miles. On the other hand, if you use your vehicle for on-road driving, one interval can last for 7500 and even 10000 miles.
Choosing the best oil for Jeep 4.0 Engine is a difficult task. You have to avoid products that have performance problems and cause nothing but damage to your vehicle.
This list of these top products which I thought were excellent for the Jeep 4.0 engine, have not only been highly tested by people but are made by highly regarded brands too.
I would recommend the Castrol 03081 to you. It provides you the perfect balance between performance and engine health. Its Fluid Titanium technology is on the next level. No matter which product you choose, you will be more than content with your decision as long it is from this article.
