For every vehicle, you know how vital engine oil is. As the human body needs food to live, automobiles need oil. Oil is like a shield for the engine’s moving parts. So it’s essential to use the best engine oil for your car. Kirkland and Mobil 1, two brands of synthetic lubricants, often compete for the top place. Both of these oils are top engine oils. But when choosing engine oil, some people need clarification about what suits a car. We will discuss Kirkland vs. Mobil 1 to help you select the proper one.
Mobil 1 Synthetic Oil Reviews:
Do you want to know who makes Mobil 1? Mobil 1 is manufactured by ExxonMobil, one of the most famous brands in the lubricant sector. Mobil 1 synthetic motor oil was manufactured by the same team that produced motor oil in Alaska in the late ’60s.
Then ExxonMobil released a new motor oil type to revolutionize the industry in 1974. This oil is Mobil 1 synthetic motor oil, created from a synthetic base stock. It comes with high quality and provides higher-performance additives. Besides, Mobil 1 took off immediately and became interchangeable with synthetic motor oil.
Although it is expensive, its performance will give you excellent returns. It can lubricate your car’s engines in every component. This ensures the maximum efficiency of the machine. Besides this, the viscosity may not affect how many miles you cover. It preserves functionality and color.
Moreover, oil preserves engine parts for a long time and prevents sludge build-up in your vehicle’s regulators. After using this oil, you don’t need to exchange it frequently, so you can save money.
Kirkland Full Synthetic Oil Reviews:
A well-known brand, Costco, markets Kirkland’s engine oil. Costco’s Kirkland engine oil was first introduced in 2004. In addition, Costco is a big chain of retail shops, but some say they don’t manufacture this oil.
In addition, it is manufactured by the Warren Distribution Company. Typically, this company is quite old and North America’s most significant oil distributor. For Costco, this Warren company makes Kirkland motor oil.
Kirkland has shown his skills to the world as a game-changer engine oil. Thus, this ideal oil extends engine efficiency and prevents thermal breakdown. Furthermore, it decreases corrosion. Notably, this synthetic oil is certified for engines, so you can safely use it.
It comes to cleaning engine internal parts, reducing wear, and delivering extreme fuel efficiency. These oils have different viscosities, like SAE 5W20, 0W20, and 5W30. Among them, the 0W20 features a better version. However, as synthetic motor oil, Kirkland always satisfies its users.
Comparison Between Kirkland Synthetic Oil Vs. Mobil 1:
For you, we have made a comparison between these famous brands. After reading this comparison section, you can decide before picking engine oil. Let’s discuss:
Durability
Accordingly, Mobil 1 oil has an average shelf life of about five years. Regardless, it is essential to remember that this is only an estimate. The actual shelf life will be shorter or longer depending on many factors. For example, it can be changed, including how the oil is stored and under what conditions it is used. Kirkland motor oil has an average shelf life of three to five years. Yet, it can last up to five years when stored in a cool, dark place.
Fuel Economy
Kirkland fuel economy features are very close to Mobil 1. Since Mobil 1 is performance oil, it doesn’t have good fuel economy. The brand is relatively premium and is more focused on liquid quality.
Regarding fuel economy, the Kirkland synthetic oil is a little bit good. Generally, Kirkland oil viscosity grades are limited and optimized for the most efficient fuel use. Therefore, these oils are comparable to Mobil 1 in this category.
The Price
Kirkland synthetic oils are very affordable. On the contrary, Mobil 1 is a costly undertaking. Kirkland’s unique selling point offers quality oil at affordable prices. For people who are looking for good quality oil at an affordable price, Kirkland can be a great option. We can’t say the same about Mobil 1, though.
Longevity:
Accordingly, Mobil 1 is known for its longevity, and it takes quite a long break to change. The longer engine oil lasts, the more profitable it is for the customer. Good oil should maintain engine health, though, and the Mobil 1 does just that. Hence, it lasts for a long time and protects your engine. In contrast, Kirkland synthetic oil lasts longer but less than Mobil 1. Mobil 1 comes with a high life expectancy.
Engine Performance
As both Kirkland and Mobil 1 have synthetic oils and quality additives, they ensure optimal motor performance. But Mobil 1 is best for new and old cars. Kirkland is famous for its old-engine vehicles, and it provides maximum engine performance.
Versatility:
Eventually, Kirkland allows your engine to start smoothly in cold weather thanks to its low-temperature fluid. That’s like a reliable oil that provides the best weather performance in both weather. But Mobil performs equally. That means its 5w30 grades ensure fast oil flow when cold and remain stable during hot. These characteristics make this oil unique, unlike other oils.
Protective Wear
In general, Kirkland contains anti-wear additives that create a protective wall on engine parts. Yet, it protects the engine from friction and wear, helping it run longer and perform better.
The Mobil 1 has its own set of armor. Its advanced formula is enriched with friction-reducing additives to protect your engine from wear. After using this oil, your motor stays healthy and can feel comfortable.
Compatibility
You can use Kirkland oil in various vehicles with gasoline engines. In particular, this oil is also compatible with conventional oils. So it provides a flexible option if you’re considering a change. Consequently, Mobil 1 also shows off extensive compatibility. Whether you want to use it on a sports car or a minivan, this oil is probably the right fit. Still, this oil also mixes well with traditional oils, so upgrading to Mobil 1 is a trend.
Which Brand Is Better?
It’s up to you to decide Kirkland vs. Mobil 1, which is better? and what they can consider. But basically, Mobil 1 oil is the best oil on the market despite the price. Without any doubt, it can prevent evaporation and can flow when exposed to extreme temperatures. Before deciding which brand is ideal for your vehicle, you should read their review carefully.

Kirkland Vs. Amsoil:
Kirkland uses Warren Oil as their manufacturer. Warren blends additives in a base oil. Like other oil companies, Kirkland Oil also has API licenses to monitor the quality of the oil. Kirkland is the best oil which is good enough for most drivers and their cars.
Amsoil doesn’t like Kirkland. They purchase an additive pack, or they create it themselves. Besides, Amsoil also has an API license to fulfill the oil’s minimum quality. Plus, this oil does not go to automakers to test their oil. As an oil analysis, we want to go for Amsoil. The reason is that it contains lots of additives. Mainly, the higher oil additive can clean better but can be more distressing to the seals.
Both brands have GF-6 licensed oils; search the Starburst symbol. You will pay more for Amsoil, The additive is not cheap, but as long as it is Starburst, it will work in your car. Both brands have GF-6 licensed oils but look for the starburst symbol. Lastly, you will want to spend more money on Amsoil because it will be best for your vehicle.
