For the 2018 Nissan Maxima, premium fuel is advised but not mandatory. The manual suggests using premium unleaded gas with a rating of at least 91 AKI. If you opt for a lower fuel grade, modern vehicle technology can adjust for varying octane levels. However, using lower-quality fuel may lead to decreased horsepower and MPG, alongside higher CO2 emissions. Your driving habits play a significant role in fuel efficiency – aggressive acceleration wastes fuel while unnecessary braking squanders the energy used to gain speed.
I own a 2017 Nissan Maxima LS. Is it safe for me to use regular gasoline?
I've been using regular gasoline with my car's 18-gallon fuel tank to its full capacity.
Every 2018 Nissan Maxima comes with identical drivetrains, transmissions, and 3.5-liter engines. Whether it's the Maxima S, Maxima SV, Maxima SL, Maxima SR, or Maxima Platinum, they all require premium unleaded gasoline exclusively and cannot run on regular gas.
It is highly suggested to use lower octane fuels in the engine to prevent potential damage. Choosing lower octane fuel is recommended because the engine is equipped with ping sensors that allow it to adjust accordingly. However, using lower octane fuel may result in decreased performance and fuel efficiency. The engine control systems are impressive mechanisms that are capable of adjusting to different fuel types. 😊
You have the option to utilize 89 octane or regular gasoline. If your knock sensors are functioning properly, the computer will simply adjust ignition timing, leading to a slight decrease in power output, which shouldn't be very noticeable during regular driving. However, avoid using regular gasoline if your check engine light is illuminated.
