Should Infiniti Use 92 or 95 Octane Gasoline?
2 Answers
Infiniti vehicles require a minimum of 95 octane gasoline. Not recommended to switch to lower octane fuel: Under normal circumstances, it is not advisable to switch to a fuel with an octane rating lower than the standard specified in the vehicle's manual. Using lower octane fuel may cause premature combustion, leading to engine knocking. Additionally, incomplete combustion can increase carbon deposits, potentially clogging the fuel injectors and intake manifold, while also reducing engine performance and increasing fuel consumption. Follow the manufacturer's fuel recommendation: In summary, always use the fuel grade printed on the fuel filler cap or a higher grade, but never use a lower grade than recommended.
I've been driving an Infiniti for several years and often get asked whether to use 92 or 95 octane fuel. Generally, 95 octane is more suitable because the engine is designed for higher-octane fuel, resulting in smoother and more stable performance with less noise. While 92 octane is cheaper, it may cause engine knocking, long-term engine damage, and increased fuel consumption. I tried using 92 octane once, and the engine had noticeable jerking and slower acceleration. I recommend checking the owner's manual for the specified fuel—most Infiniti models require 95 octane. Don’t try to save a little money only to end up with costly repairs. During regular maintenance, consult professional technicians who emphasize that matching the correct fuel grade is key. Safe driving is the priority—don’t cut corners with fuel strategies. Keeping your engine healthy ensures a worry-free and enjoyable driving experience.
