Does the Infiniti QX60 require premium gasoline?
Infiniti recommends premium-grade gasoline for the QX60 and regular for the QX60 Hybrid.
To new for my books. Check in the owners manual it will tell you for sure what fuel grade to use. You should take some time and read the owners manual anyway as there is a lot of information you will find very vital to keeping your vehicle in top condition.
Most likely, most luxury cars do. Check the Infiniti website.
