I am not hearing and enginee noises. [2020, 370Z Sport Touring]

It honestly doesn’t matter what your driving habits are because Nissan/Infiniti highly recommends only using premium 91+ octane pump gas fuel in our 370Z’s. Also Nissan/Infiniti only recommends using top tier gasoline in our cars as well running cheap low quality less expensive fuels in our cars will only hinder performance and over time add to carbon build up and deposits in your engine. If you own basically a new 2020 370Z don’t risk detonation by using 87 or 89 octane not good. In the hot summer months you are asking detonation/pinging and possible engine damage over time by not running the correct fuel. As stated if you can not afford premium top tier gasoline for your Z then you really can not afford to own a 370Z. For pump gas I will only use Chevron 93 or Texaco 93 octane. Any quality top tier gasoline will work just fine as long as it is 91 octane or higher. Be selective of what gasoline you choose to use in your Z because Nissan/Infiniti vehicles were always sensitive to cheap inexpensive low quality fuels be careful.
