Do you want to keep your 2018 Jeep Compass running like a champ? The secret lies in choosing the right oil. Whether you’re clocking city miles or heading off the beaten path, the right oil type can make a world of difference in performance and engine health. Let’s unpack what works best and why synthetic oil often gets the top spot.
A Quick Look Under the Hood of the Jeep Compass
The 2018 Jeep Compass is powered by a 2.4-liter 4-cylinder engine with 180 horsepower at 6,400 RPM and 175 lb-ft of torque at 3,900 RPM. Its single overhead camshaft (SOHC,) 16 valves, and variable valve timing (VVT) work together to deliver smooth operation and reliable efficiency.
It’s paired with a six-speed automatic transmission that, along with its on-demand four-wheel drive, keeps you moving confidently, whether on the highway or the trail. You get a solid tow capacity of up to 2,000 pounds and an EPA-estimated 22 MPG in the city and 31 MPG on the highway.
For oil type, Jeep recommends 0W-20. You can choose either conventional or synthetic, but synthetic brings added benefits, like less frequent oil changes and extended engine protection. The oil capacity for your Compass is 5.5 quarts, filter included, and it’s important to make sure the oil meets standards like API SP, SN Plus, or GF-6A, among others.
Why Synthetic Oil Stands Out
Synthetic motor oil is engineered for a reason—it’s made with consistent molecules and no impurities. This makes it more efficient at reducing friction, improving fuel economy, and holding up under extreme temperatures. It also protects your engine from wear better than conventional oil.
Conventional oil, on the other hand, is refined from crude oil. This process doesn’t fully remove impurities like sulfur or metals, which can lead to uneven performance and reduced effectiveness. These differences are key when considering options for your Jeep Compass.

What’s the Benefit of Synthetic Oil?
Synthetic oil takes engine performance up a notch. Its formulation ensures better lubrication, which keeps parts moving smoothly. For you, that means longer oil change intervals, better fuel efficiency, and less engine wear over time. It’s especially effective during extreme hot or cold conditions, making it a reliable choice no matter where the road takes you.
For Jeep Compass owners with higher mileage, Quaker State® High Mileage 0W-20 Full Synthetic Motor Oil is a great option. Specifically designed for engines with over 75,000 miles, this oil helps reduce leaks, burns, and sludge buildup. It’s a solid pick for maintaining your engine’s long-term health.
Another excellent choice is AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil. Known for its durability and reliable performance, AMSOIL delivers consistent protection while enhancing fuel efficiency and engine cleanliness. While both are well-suited for your Compass, AMSOIL typically excels in handling extreme conditions.
Long-Term Protection for Your Jeep Compass
Synthetic oil doesn’t just boost performance—it also helps protect your investment. Switching to synthetic gives your engine better resistance to deposits, corrosion, and sludge. Over time, this reduces the risk of costly repairs. Think of it as an extra layer of security, especially if you plan to keep your Compass running strong for years to come.
