What type of fuel should a Ford Raptor use?
1 Answers
Ford Raptor should use 92-octane gasoline, as this fuel grade is recommended in the vehicle's official owner's manual. In addition to checking the appropriate fuel grade in the owner's manual, Ford Raptor owners can also find this information on the fuel tank cap, which is usually labeled. Typically, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a ratio between 10.0-11.5 should use 95-octane gasoline. For higher compression ratios, 98-octane gasoline is recommended. However, with the application of new technologies, the fuel grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower-octane fuel due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the fuel grade, the higher the octane rating and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If a Ford Raptor is occasionally filled with the wrong fuel grade, simply switching back to the correct grade after use is sufficient. However, long-term use of the wrong fuel grade can have the following effects: For vehicles recommended to use lower-octane fuel, using higher-octane fuel will not cause damage, but the increased octane rating can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher-octane fuel, using lower-octane fuel can cause engine knocking. Due to the significantly lower octane rating, the fuel's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will develop during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in extreme cases.
