Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What type of fuel is recommended for the 2016-2020 Kia Sorento?

The 2016-2020 Kia Sorento is designed to run on regular unleaded gasoline with an octane rating of 87 or higher. Using higher-octane fuel is not required but may improve performance in certain conditions. Diesel or ethanol blends above 15% (E15) are not recommended as they can damage the engine and void the warranty. Always refer to the owner’s manual for specific fuel requirements.

Q2

What are the maintenance requirements for the fuel system in the Kia Sorento?

The fuel system in the 2016-2020 Kia Sorento requires regular maintenance, including fuel filter replacement every 30,000 miles and fuel injector cleaning every 60,000 miles. Use high-quality fuel to prevent buildup in the system. Inspect the fuel lines and connections annually for leaks or wear. Follow the recommended service intervals in the owner’s manual to ensure optimal performance and longevity.

Q3

How do I replace the fuel filter in a 2016-2020 Kia Sorento?

To replace the fuel filter, first, relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Disconnect the negative battery terminal. Locate the fuel filter, typically under the vehicle near the fuel tank. Disconnect the fuel lines and mounting bracket. Install the new filter, reconnect the lines, and secure the bracket. Reconnect the battery and start the engine to check for leaks.

Q4

What should I do if my Kia Sorento has poor fuel efficiency?

Poor fuel efficiency in the Kia Sorento can be caused by several factors. Check for clogged air filters, low tire pressure, or malfunctioning oxygen sensors. Ensure the fuel injectors are clean and the fuel system is free of leaks. Use the recommended fuel grade and avoid excessive idling or aggressive driving. If issues persist, consult a certified technician for a diagnostic check.

Q5

How can I optimize the fuel performance of my Kia Sorento?

To optimize fuel performance, maintain proper tire pressure, use high-quality fuel, and replace air and fuel filters as recommended. Avoid carrying unnecessary weight and reduce aerodynamic drag by removing roof racks when not in use. Drive smoothly, avoiding rapid acceleration and braking. Regularly service the engine and fuel system to ensure peak efficiency and performance.
