Can the Nissan Patrol use 92 octane gasoline?
2 Answers
The minimum fuel grade requirement for the Nissan Patrol is 95 octane, and it cannot use 92 octane gasoline. Gasoline is a colorless to pale yellow mobile liquid at room temperature, hardly soluble in water, flammable, with a distillation range of 30°C to 205°C, and explodes when the air concentration reaches 74-123 grams per cubic meter. Below are the characteristics of gasoline: 1. Volatility. Gasoline must rapidly vaporize and form a uniform combustible mixture with air in the engine cylinder, which is primarily determined by gasoline's inherent volatility. The main indicators reflecting volatility are distillation range and saturated vapor pressure. 2. Stability. The ability of gasoline to resist oxidation under normal temperature and liquid phase conditions is called gasoline's oxidation stability, or simply stability. The indicators for evaluating gasoline stability include iodine value, actual gum, and induction period. 3. Anti-knock quality. The property that measures whether a fuel is prone to knocking is called anti-knock quality, which is expressed by the octane number (RON) of gasoline. The higher the octane number of gasoline, the better its anti-knock quality. 4. Corrosiveness. Gasoline corrosiveness is related to sulfur and sulfur compounds, organic acids, and water-soluble acids or bases. 5. Cleanliness. Gasoline often contains mechanical impurities and water. Mechanical impurities can cause severe consequences such as clogged fuel lines and increased wear. Water mixed into gasoline accelerates gasoline oxidation and reacts with low molecular weight organic acids in gasoline to form acidic aqueous solutions that corrode metals. At low temperatures, water can freeze and form ice particles that clog fuel lines. Therefore, mechanical impurities and water must be strictly controlled in automotive gasoline.
I've been driving a Patrol for many years, and seeing you want to use 92-octane fuel, I'd like to share some experience. The Patrol's engine is designed for high performance and typically requires 95 or 98-octane gasoline. Using 92-octane is really not suitable. 92-octane has a lower octane rating, making it more prone to knocking issues—that's the sound of abnormal ignition inside the engine. I tried using 92-octane once in a remote area, and the car had obvious jerking, sluggish acceleration, and even triggered the check engine light. In the long run, it can damage engine components like spark plugs or piston rings, and repairs can be extremely costly. The manual is the bible—always check the minimum octane rating specified in the manual first. Occasionally using 92-octane in emergencies might not be a big deal, but don’t make it a habit. For the car’s health, sticking to higher-octane fuel is more cost-effective.
