The fact is that depending upon the Jeep Wrangler model that you are driving, you may require different filter types.

Buyer’s Guide
I am more than sure that you couldn’t have even thought that Jeep oil is such a complex notion that deserves such a complex investigation, could you? Well, you shouldn’t worry since you are not the only one, and there is nothing to be ashamed of. We are going to discuss all the crucial points when it comes to choosing the right oil for your vehicle in detail so that there are no questions left unanswered.
Oil Viscosity Basics
When you are about to change or purchase some engine oil for your Jeep, the first thing that you come across is the oil viscosity and the oil marking related to that very viscosity. First of all, we are going to try to define what viscosity stands for. When applied to engine oil, viscosity defines the resistance of oil to flow at a certain temperature. If you wonder how viscosity is the measure, the process is quite basic at its core. The oil is heated up to a specific temperature and then poured through a special hole. The time it takes for the liquid to get flow through that hole defines the level of oil viscosity. If the oil is thin – it flows faster, the thicker it is, the longer it takes for the oil to get through the hole.
Now, after, we have figure what viscosity is out, it is time to talk about those different numbers on most of the oil bottles. If you think that they are defining the same thing – you are deeply mistaken, and all these letters and figures should be read carefully if you want to feed your engine with the right oil.
I am going to start with the letter W. there may be many suggestions as to what it stands for, but there is only one true meaning for it – Winter. The number before the W letter defines the level of oil’s viscosity during wintertime. The fact is that thinner oils are more preferable for colder seasons. In case you do not know it, during the colder seasons, it is essential that most internal parts of the vehicle get some oil at startup so that those parts do not wear out before time. Thinner oil can get to those parts faster than the thick one.
As you can see, there are some numbers after the W letter, and I am sure that you wonder what those are there for. The fact is that their goal is pretty much the same since they are also related with viscosity. The truth is that the numbers following W indicate the viscosity of the oil at the temperature 100C/212F. Once again, the lower is the indicating number the thinner is the oil and vice versa.
Let’s talk about the reasons why you would want to change between different oils during cold and warm seasons. I have already mentioned that thinner oils are great for cold seasons since they lubricate all the working parts during the startup and prevent immature wear. However, when the temperatures get high, thin oils will simply drop off the parts that require lubrication and lead to immature wear once again. Thus, thicker oils are used during warm seasons to prevent the outcome.
Oil Types
When you think that now that you know all about the viscosity and all those numbers and letters depicted on the oil bottle, you can easily choose the right oil for your vehicle. However, you need to be aware of the fact that there are also as many as four types of oils to distinguish too.
Conventional Oil
Conventional oil is the cheapest of all. Such low prices are defined by the method of oil extraction since traditional drilling is applied, so the price is corresponding. It can be even added that conventional oil is the oldest oil type there is. However, that fact that is not an artificially created product makes it somewhat less convenient than it should have been. The thing is that conventional oil should be changed every four months the least, or every 3000 miles, while other oils can last a lot longer without any loss to the quality. When it comes to low temperatures, most providers suggest 5W-20 or 5W-30 oil types and 10W-30 for warmer seasons.
Full Synthetic
Just as the name has it, this type of oil is made of synthetic components and that makes is a little more expensive when combined to conventional oil. What is more, you do not need to change fully synthetic oil sooner than 7000 miles and it is great at both high and low temperatures. Due to the fact that synthetic oil contains almost no contaminants and is so temperature-resistant, it is usually advised for all sorts of high-performance vehicles such as Jeep. On the darker not, this type of oil is a lot more expensive when compared to conventional oil.
Synthetic Blend Oil
There is a third type of oil on the market, too – it is called a synthetic blend. It will not take you long to figure out that it is a mixture of conventional and synthetic oils. This is the particular oil type that most SUV and pick-up drivers prefer most. It is a bit more expensive than conventional oil, but it is also more temperature resistant, which is also a plus. Besides, due to the fact that it reduces evaporation, it is also increases fuel economy.
High-Mileage Oil
Lastly, there is also a type of oil specially designed for older vehicles. The fact is that those vehicles that have a mileage over 75K tend to have worn-out crankshafts, which result in various types of leakages, especially at low temperatures. High-mileage oil contains special seal conditioners that are designed to patch up those crankshaft seals and prevent or minimize the leakage.
So, which oil would be the best for your vehicle? It depends upon a list of factors. First of all, if you have an old Jeep with a simple engine and you do not want to overpay for oil, then the conventional type would suit you best. On the other hand, high-mileage oil is a lot better for older engines, but it is quite pricey. Lastly, if you are driving around a lot and weather conditions tend to change dramatically, then fully synthetic oil would be your best bet.
Oil Specs
Just like any other vehicle-related product, the oil comes with certain specifications that you should be able to differentiate between. The fact is that every Jeep owner needs to be able to define oils’ performance, whether or not it corresponds with the recent quality and safety tests, and so on.
Since we are talking Jeeps here there are three main specs types that you should be aware of:
API – stands for American Petroleum Institute and represents the service category together with the phrase – Resource Conserving. The primary purpose of the specification is to define that it is fit for gasoline engines when we are thinking Jeeps. Besides, such a mark represents that the oil is certified and tested according to all the modern standards.
Dexos1 – it is a specification designed for GM vehicles solely. If you own one, you should better check it out too.
ACEA – these are the European specs that are the same as API for Americans.
The fact is that any quality oil is supplied with both API and ACEA specifications.
Oil Change Period
Of course, I have already figured it out that you need to change engine oil from time to time. However, most beginning drivers may wonder as to how often you should do that. Well, if you are a lucky owner of a newer Jeep Wrangler, starting with 2018 – there is nothing to worry about, the vehicle will tell you precisely when to do that. The fact is that the vehicle is provided with a special indicator that signals about an oil change.
In case you own a little older vehicle. There is a list of factors to consider before you decide to change the oil. First of all, you need to pay attention to the conditions that you are driving under, if there are deemed severe, then 3500 miles is the high time to change that oil. Under normal driving conditions, you can start to think about oil change when you get to the point of 10 000 miles tops. The experts say that 350 driving hours or 12 months of vehicle exploitations are viewed as the maximum period that you can use the vehicle without changing motor oil.
Also, it is essential that you check the following points out when you are at the service and having the oil changed:
- Filter change
- Tire rotation
- Battery inspection together with the terminals
- Engine cooling system checked
- Brake pads and other related details inspected
- Exhaust system checked
If you keep these simple rules in mind, your vehicle will serve you a lot longer than you think.
Oil Filters
When it comes to Jeeps, there are two main kinds of filters there are to choose from.
Cartridge Oil Filters – these are full-flow filters. They are mostly very simple in use and can be inspected without the need to change the oil if mounted in an upright position. What is more, mostly, these filters do not contain any metal parts and are a lot easier to recycles after use.
Spin-On Oil Filters – these are also full-flow Filters, but they come packed with a steel canister. These filters are designed for ‘home use’ since almost anyone can manage to install those.
Conclusion
To sum all up, it is safe to say that there is a reason why there are so many oil brands and types on the market these days. Engine oil is that engine food that it is cannot operate well without. The better is the nutrition, the longer and the better your Jeep will serve you. That is why the next time you are about to change your engine oil, you need to consider a list of important factors before making the final decision. I have tried out best to explain all the details concerning all types and specifications of motor oil so that even a beginning driver will be able to make the right choice in times of need.
