What grade of gasoline does the Pajero use?
2 Answers
The Pajero uses 92 octane gasoline. Gasoline anti-knock properties: The anti-knock substance in gasoline is isooctane. The ability of gasoline to resist knocking when burning in the engine is its anti-knock property. The octane rating of 92 or 95 represents the fuel's anti-knock property. The higher the octane number, the greater the isooctane content, indicating better anti-knock performance. Gasoline anti-knock value: Different engines require different anti-knock values. Similarly, different octane grades of gasoline are suitable for engines with different compression ratios. The higher the compression ratio, the higher the octane grade of gasoline required. Gasoline compression ratio: The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center.
I've been driving my Pajero SUV for many years and always stick to 93-octane gasoline. The engine runs smoother with less noise. Occasionally tried 92-octane, and the engine would have minor vibrations, especially noticeable when climbing hills in mountainous areas. This vehicle is designed for higher octane fuel with a higher compression ratio. While 92-octane can be used, it might lead to some carbon buildup, potentially increasing maintenance costs in the long run. I recommend using 95 or 98-octane whenever possible, especially for long summer trips—it ensures stability and even saves some fuel. My average fuel consumption is 0.5 liters lower than my colleagues'. During maintenance, the mechanic mentioned that higher-octane fuel extends engine life, reducing the need for part replacements. For daily city driving in traffic, 93-octane is sufficient—don’t risk using lower-octane fuel just to save a bit.
