What kind of oil does the 2018 Honda Civic use? 

Whether you get the turbo 1.5L (91 ci) or 2.0L (122 ci) four-cylinder engine, always use 0W-20 weight motor oil. Before you buy oil, look for the label that indicates the formula is certified by the American Petroleum Institute (API).   

If you’d like even more information about what oil to use in your 2018 Civic, you’ve come to the right place. You can find out everything you need to know by simply reading through this article at your leisure.

Why You Should Use the Recommended Oil for the 2018 Civic

Every car, truck, and van ever made uses a specific oil weight, or viscosity number. In the past, your average vehicle simply used 10W-40, but all that has changed in recent years. As engines have become more complex, engineers have dialed in the oil weight to better protect the internals from damage.

By using the recommended viscosity number, the oil can adequately reduce heat and friction inside the engine. This prevents your internal parts from wearing down prematurely, so your car can remain on the road for as long as possible.

A thinner oil flows better through all the passageways but doesn’t have the heat dissipation qualities of thicker formulas. Thick oil has poor flow but keeps heat to a minimum. Car manufacturers have to find the perfect balance to keep all the moving parts well lubricated and as cool as possible.

The 2018 Honda Civic’s Recommended Oil Type and Amount

As shown in the video above, it’s quite easy to tell when to have your oil changed next. It’s a little bit more difficult to know just what type of oil to use and in what amount. Thankfully, the owner’s manual has you covered.

In that manual, you’ll find that Honda recommends using the highest grade 0W-20 motor oil. You can use this oil weight in all temperatures since it works just as well at -20 degrees as it does at 100 degrees Fahrenheit. You can choose between conventional and synthetic oil as long as you use the right viscosity number.

Although they recommend that you get Genuine Honda Motor Oil, you can choose from the many other commercial brands. Just make sure to always look for the API certification seal before you buy any oil. Also, remember to never use any engine oil additives since they can potentially damage internal parts and reduce your car’s performance.
