What type of gasoline should the new Sylphy use?
2 Answers
The new Sylphy uses 92-octane gasoline. The grade of gasoline is classified by octane rating, with 92-octane gasoline referring to a fuel that has anti-knock performance equivalent to a mixture of 92% isooctane and 8% n-heptane. The higher the octane number, the better the anti-knock performance. The appropriate gasoline grade should be selected based on the engine's compression ratio, which is specified in the vehicle's manual. The Sylphy is a compact sedan under Nissan, with dimensions of 4641 mm in length, 1815 mm in width, and 1450 mm in height, and a wheelbase of 2712 mm. In terms of power, this car is equipped with a 1.6-liter naturally aspirated engine that features EVTC technology and multi-point fuel injection, with an aluminum alloy cylinder head and block.
My Nissan Sylphy has been running for over three years, and the fuel tank cap clearly states unleaded gasoline with an octane rating of 92 or above. The 4S dealership advised at delivery that 92 is sufficient, and there's no need to use 95. The HR16 engine in this Nissan has a compression ratio of 11.7, which isn't particularly high, so 92-octane fuel won't cause knocking. Last week, I did the math while refueling: 92 is 0.6 yuan cheaper per liter than 95. Based on driving 1,000 kilometers per month, this saves nearly 1,000 yuan in fuel costs annually. However, it's important to avoid small gas stations—Sinopec and PetroChina's 92-octane fuel is more reliable to prevent fuel injector clogging.
