Should the Dodge Journey use 92 or 95 octane fuel?

[LandonLee]

The minimum fuel octane rating required for the Dodge Journey varies depending on the model. The 2.4L model has a minimum requirement of 92 octane, while the 3.6L model requires at least 95 octane. The diesel version uses No. 0 diesel fuel. Here is some related information about 92 and 95 octane gasoline: 1. The most commonly used gasoline grades for gasoline engines are 92 and 95 octane. In fact, there is no difference in fuel quality between these two grades. 2. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline is composed of 95% isooctane and 5% n-heptane. The different proportions of isooctane and n-heptane in these two fuel grades result in varying anti-knock properties, with higher isooctane content providing stronger anti-knock performance.

I always believe that the first principle for Dodge Journey owners is to refer to the owner's manual, which clearly states the recommendation to use 95-octane gasoline because it corresponds to a high octane rating, preventing engine knocking. Once, I carelessly filled up with 92-octane fuel, and the engine started making that rattling knocking sound. Switching back to 95-octane quickly restored normal operation. The manual is the authoritative guide—don’t take risks guessing; prioritize safe driving. High-octane fuel reduces carbon buildup and wear, making it more worthwhile for long-term engine protection. During routine maintenance, technicians also emphasize strictly following the manual for fueling to avoid turning minor issues into major failures. Remember this small habit—it makes driving much more reassuring.

In my car usage experience, cost is a major concern: 92-octane gasoline is cheaper, saving a few cents per liter, and filling up a tank can save dozens of yuan, which sounds cost-effective. However, the Dodge Journey's engine is designed for 95-octane fuel, and using 92-octane may reduce fuel efficiency, increasing consumption by one or two liters per 100 kilometers, ultimately not saving money. I tried comparing expenses over several months: although the initial cost of using 95-octane fuel is higher, the engine runs smoother, and repair costs are significantly lower. Considering all factors, 95-octane is the smarter choice—don’t try to save small amounts only to invite bigger troubles. This investment in the maintenance budget is worth it.

Using 95-octane gasoline in the Dodge Journey significantly enhances the driving thrill: quicker throttle response, smoother acceleration, and explosive power. The car's high engine compression ratio perfectly matches the 95-octane rating, reducing knocking noise. During a track test drive comparison, I noticed 92-octane made the power feel sluggish, while 95-octane delivered full vigor and even protected the pistons. For daily driving, this choice directly impacts both performance and longevity—worth the extra cost.
