Synthetic vs Conventional Oil near Oak Lawn, IL

Synthetic vs Conventional Oil near Oak Lawn, IL

Changing your vehicle’s oil is one of its most important maintenance tasks, but you might be wondering what kind to use. That’s why we at Evergreen Kia put this overview together outlining the difference between synthetic and conventional fluids! After reading on, visit our dealership so that you can get maintenance prior to your next adventure down Harlem Avenue.

Conventional

Motor oil is essential for keeping your automobile’s engine running smoothly. It lubricates the inner workings of the powertrain so that friction doesn’t build up. Without such a fluid, you can expect the vehicle to overheat in hardly any time at all! It also maintains the cleanliness of the engine by collecting dirt and debris as it circulates the system. Conventional fluid is made from refining crude oil, and it usually lasts approximately 5,000 miles. Regardless of how far you drive, you should get a new batch at least twice a year. In doing so, you can improve the efficiency, performance, and longevity of your Kia Telluride or Rio!

Synthetic

If you are hoping to spring for a more advanced fluid for your vehicle, then you might like to try out synthetic oil. This newer addition to the automotive industry is more highly refined than its predecessor. Therefore, it lasts much longer, often up to 10,000 miles. That means you can drive far down I-294 without needing more service. The reason that it takes longer to degrade is due to the fact that its structure consists of long strands of molecules that are difficult to break. This results in a durable substance that retains its viscosity while the engine runs. Clearly, there are benefits to choosing this liquid for your Oak Lawn adventures. To learn even more, contact us!

Which Is Best?

Now that you have an idea of how these fluids differ, you should learn more about which one to choose. Both of them have their strengths and weaknesses, so it is important to know what your automobile requires. Some older vehicles are only compatible with conventional oil, while many modern rides require a synthetic variety. Traditional substances work with many different kinds of cars, trucks, and SUV, and you can also expect to pay less. However, synthetic alternatives last longer even though they cost more, meaning the price tends to balance out over time. Use our Ask a Tech form to see what our mechanics recommend!

How Often Should Your Oil Be Changed?

  • Some rides can go upwards of 5,000 miles before needing new oil, but high-mileage autos often need it every 3,000 miles.

Joe and John were a great tag team to ensure that I received a great experience, they were transparent, upfront, and did not send me in circles. I was in and out in 120 minutes, I received the SUV that I wanted and they did not try and sale me on anything extra that I did not need! Great team, atmosphere was friendly and everyone spoke and they were excited for me to ring the bell. I would definitely refer someone here and they ensured that any Kia concerns were addressed! Thanks Fellas! Keep making customers feel valued!

I can’t say enough good things about my experience at Evergreen Kia, and that’s all because of Casey Jones. He made what’s usually a stressful process feel effortless and exciting. Casey was honest, attentive, and truly cared about making sure I got exactly what I wanted. This was hands down the best car-buying experience I’ve ever had. Evergreen Kia is lucky to have him!

Shout out to Casey who felt like more of an advocate than a sales person. Also thank you to management who approved the great deal that we got! I would say to anyone buying a Kia, it only males sense to buy it here due to the benefits and warranties given by this particular dealership location.

(Translated by Google) undefined (Original) Was referred to this Kia and it didn’t disappoint, Joe worked with me through it all and helped me pick my car i love! I recommend if you go to any Kia to stop by in evergreen first, they dont try To play games and work with you on what you want! New to all of this but if i can I’d recommend going here first and you’ll see!
