What's Happening?
In the U.S., only a few new vehicles require 89 octane fuel, specifically models from Stellantis subsidiaries Dodge and Ram. These vehicles, including the Ram 1500 and Dodge Durango, are equipped with the 5.7-liter Hemi V8 engine, which necessitates mid-grade
gasoline. Despite the low demand for 89 octane fuel, gas stations continue to offer it because it can be created by blending regular and premium gasoline, eliminating the need for dedicated storage. Most vehicles in the U.S. are designed to run on either regular 87-octane or premium 91-plus octane fuel, with no significant performance benefits from using higher-octane fuel in vehicles not designed for it.
Why It's Important?
The information is crucial for vehicle owners to understand the specific fuel requirements of their cars, which can impact engine performance and longevity. Using the correct octane level is essential for maintaining vehicle efficiency and avoiding potential engine damage. The continued availability of 89 octane fuel, despite its limited necessity, reflects consumer misconceptions about fuel grades and their impact on vehicle performance. This situation highlights the need for better consumer education regarding fuel choices and their implications.
