What grade of gasoline should the SYM Fiddle 4 use?
3 Answers
SYM Fiddle 4 uses 92-octane gasoline. The Fiddle 4 was introduced to the domestic market this year. In terms of appearance, it follows a retro-style scooter design, featuring an integrated LED headlight for both high and low beams at the front. The front also includes turn signals on both sides and a position light in the center. How to determine the appropriate gasoline grade for a motorcycle: The suitable gasoline grade for a motorcycle depends on the engine's compression ratio. Generally, motorcycles with a compression ratio below 9.5:1 are suitable for 92-octane gasoline, those with a ratio above 9.5:1 are better suited for 95-octane, and those below 10.0:1 are ideal for 98-octane. The owner's manual will also specify the recommended gasoline grade. If the manual states '92-octane or above,' both 92 and 95-octane can be used, and there is usually no significant difference between the two. Classification of gasoline: Gasoline products can be divided into three main categories based on their use: aviation gasoline, automotive gasoline, and solvent gasoline. The first two are primarily used as fuel for gasoline engines and are widely applied in cars, motorcycles, speedboats, helicopters, and agricultural or forestry aircraft.
When riding the SYM Fiddle 4 scooter, I always find 92-octane gasoline most suitable because its 125cc engine has a low compression ratio and is typically designed to run on regular unleaded fuel. The manufacturer recommends 92 or 95-octane gasoline, but in my actual usage, 92-octane provides smooth engine operation with fuel consumption around 2.5 liters per 100 kilometers, making it economical. Occasionally trying 95-octane gasoline showed no significant power improvement, just extra cost. Small-displacement motorcycles don't need high-octane fuel as too high an octane rating may lead to incomplete combustion and resource waste. I recommend forming the habit of checking the fuel grade before refueling to avoid mixing or using the wrong type, and regular maintenance can extend engine life.
I've been using the SYM Fiddle 4 as my daily commuter for several years, always sticking with 92-octane gasoline. The engine feels responsive and the ride is nimble. When the bike was new, friends recommended 95-octane, but after trying it, I found no significant difference in fuel consumption or engine sound. Saving money to buy small accessories seemed more worthwhile. For economical motorcycles like the Fiddle 4, manufacturers typically specify 92 or 95-octane, and 92-octane is completely sufficient and cheaper. The key is to choose quality fuel from reputable gas stations—don't compromise with lower-octane fuel to avoid knocking. During routine maintenance, pay attention to the fuel tank condition and refuel promptly to avoid running on empty.
