Is Kirkland Synthetic Oil As Good As Mobil 1?: An In-Depth Discussion

Now you will know the basic features, advantages, and disadvantages of Mobil 1 and Kirkland oils in the following few steps; you can make a comparison to find which one is better for you. Of course, both engine oil has a brilliant reputation in the market, but they have distinctive features that make them better suitable for certain conditions. So, you also should consider your riding preference and conditions for putting engine oil in the diesel fuel tank.

Origin and brand reputation

Mobil 1 comes from ExxonMobil, one of the most reputable engine oil and lubricant manufacturers worldwide. Also, Mobil 1 has been one of the best engine oils for vehicles since 1974. However, the origin of Kirkland engine oil is unknown. It can be a deciding factor in Kirkland for those looking for a reputable brand.

The good thing is Kirkland engine oil enjoys backup from Costco, a leading wholesaler in the US market. So, you can also trust its performance.

Performance in low and high-temperature:

Kirkland has been formulated to provide excellent performance in high and low temperatures. If you often drive your vehicle in harsh conditions, Kirkland engine oil will offer superior engine performance and protection.

On the other side, Mobil 1 is one of the top engine oils at low temperatures. It has standard high-temperature performance, but the engine oil excels rapidly in colder conditions. If you live in cold regions with many days under sub-zero temperatures, Mobil 1 will be a lifesaver for the car. Also, you can rely on its performance in harsher days.


For most car and SUV owners, the availability of engine oil is a serious concern. They love using the oil that they can get from nearby stores. Regarding this, Mobil 1 outperforms Kirkland as the previous one is available in every automobile store.

Conversely, Kirkland is only available in Costco shops. So, finding it can be difficult sometimes. If you live in remote areas, this unavailability issue should be concerning.

Expected mileage:

As a car owner, you would like to use engine oil that lasts as long as possible. So, most car owners look for engine oil with higher mileage. Mobil 1, with more than 10000 miles of expected mileage, is a clear winner in this category.

While Kirkland engine oil has only 7500 miles of longevity, Mobil 1 can easily last for 10000-15000 miles. It, thus, ensures a longer lifespan and extended protection of the engine parts. Also, longer mileage means you must spend less on engine oil replacement. It saves you from replacing the engine oil too frequently as well.

Engine protection:

When choosing engine oil, one of the primary considerations is its protection facility for the engine against wear and tear. So, where do Kirkland and Mobil 1 engine oil stand in this category? At first glance, Mobil 1 seems to be in a winning position thanks to its 5-years of engine protection assurance which is the highest in the market.

But Kirkland doesn’t stay far behind either. Although its engine protection period isn’t marked on the product label, users have found it adequate for 4 to 5 years. Both Mobil 1 and Kirkland engine oil has been formulated from fully synthetic oil.

Also, with their almost identical additives, both engine oils ensure that your car engine enjoys maximum protection from wear and tear. However, with clear 5-year protection, Mobil 1 is slightly ahead.


Mobil 1 is one of the most expensive engine oils out there. Conversely, Kirkland is pretty pocket-friendly. So, people with tight budgets will find Kirkland engine oil a better choice. However, Mobil 1, with its higher engine protection, longer mileage, and low-temperature performance, is a good choice in the long run. It saves you from unnecessary maintenance costs.
