What Type of Fuel Does a Rolls-Royce Use?

[NathanLee]

Rolls-Royce uses 97 octane gasoline. Below are the relevant details about the Rolls-Royce Cullinan: Power: The Cullinan is a large SUV equipped with a 6.7L V12 engine featuring twin-turbocharging, delivering a maximum horsepower of 600ps and a peak torque of 900nm. Dimensions: The vehicle measures 5341mm in length, 2000mm in width, and 1837mm in height, with a wheelbase of 3295mm. It is a 5-door, 5-seat SUV with an 8-speed automatic transmission. Drivetrain: The Cullinan employs a front-engine, all-wheel-drive (AWD) system with a full-time AWD setup and a multi-plate clutch central differential.

A top-tier luxury car like Rolls-Royce requires 98-octane gasoline. I once discussed this at a high-end car repair shop, and the technician mentioned that its engine is particularly delicate. While 95-octane fuel can be used in a pinch, it tends to cause carbon buildup and affect performance. The manufacturer's manual explicitly emphasizes using 98-octane—ignoring this could cost hundreds of thousands in damages. By the way, I once saw an owner who skimped on fuel costs by secretly mixing in 92-octane, and within two months, the engine shook like a tractor. The repair bill alone could buy an ordinary car! Remember to check the small label inside the fuel filler cap—it tells you exactly which fuel to use.

Must use 98 octane! Last time when accompanying a friend to pick up the Phantom, the salesperson emphasized the fuel grade three times. The Rolls-Royce engine management system is very sensitive - if you fill up with regular 92 octane fuel, the onboard computer will directly limit power output. An auto repair shop owner once showed me a case: a customer who long-term mixed 95 octane fuel ended up with clogged fuel injectors requiring five-figure cleaning costs. It's recommended to wipe the fuel tank opening clean before refueling to prevent impurities from contaminating the fuel system. Frankly, when doing the cost-benefit analysis, those who can afford such cars really shouldn't penny-pinch on the fuel price difference.

Our fleet has been managing Rolls-Royce vehicles for five years, and our experience is to only use 98-octane fuel from the two major oil companies. Its air flow meter is particularly strict in detecting fuel quality, and lower-octane fuel can cause the sensor to falsely report fault codes. Once during a self-drive trip in Qinghai, the gas station only had 95-octane fuel, and we reluctantly filled half a tank. The next day, the engine yellow light came on. Back in the city, the inspection found that the oxygen sensor was contaminated with lead compounds. Later, we learned our lesson and always carry two bottles of fuel additive in the trunk for emergencies during long trips.

While working in Monaco, I came across quite a few Rolls-Royce owners who were particularly meticulous about refueling. An engine engineer once told me that the V12 engine has knock sensors in each cylinder. Using 92-octane fuel can generate abnormal vibration waves, which can damage the crankshaft over time. Some owners, skeptical, tried 95-octane fuel, and after six months, upon disassembling the engine, they found the valve seats cracked from the vibrations. The newer Cullinan is even more particular about fuel, with the manufacturer even recommending 102-octane racing gasoline. Also, remember to change the air filter regularly, as excessive dust can affect fuel combustion efficiency.
