NMAX's official fuel consumption is 45km/L. Here is an introduction to the NMAX155: Weight: The NMAX155 has an equipped weight of only 130kg, comparable to most 125cc sports scooters on the market. Its 1340mm wheelbase is the same as the sixth-generation Cygnus X, greatly enhancing agility. Energy-saving technology: The NMAX155 is equipped with Blue-Core energy-saving technology, combining high combustion efficiency, high cooling performance, and low power loss. Additionally, the idle stop system automatically shuts off the engine when waiting at a red light. When restarting, it integrates with the SMG intelligent start system to directly drive the crankshaft, reducing vibrations and noise during startup, achieving a fuel consumption level of 45.2km/L. Engine: The NMAX155 is powered by a 155cc Blue-Core liquid-cooled engine, balancing efficiency and performance. Besides excellent energy-saving performance, it features VVA variable valve timing to compensate for the power output gap between low and medium-high RPMs.

I usually commute on my NMAX155, with an actual fuel consumption of 2.2-2.6 liters per 100 kilometers. The bike has a 7.1-liter fuel tank, allowing me to ride about 250 kilometers in stop-and-go city traffic, and an additional 30-40 kilometers on suburban roads. I weigh 70 kilograms, and the fuel consumption increases by 0.3 liters when carrying a passenger. During the first three months after purchase, the fuel consumption was slightly higher but stabilized after the break-in period. I've tried two different oil viscosities and found that 5W-40 saves 0.2 liters compared to 10W-30. Maintaining tire pressure at 28 psi for the front and 32 psi for the rear is the most economical. On my last long-distance ride, keeping the speed around 70 km/h, I managed 300 kilometers before the fuel light came on. Fuel consumption is slightly higher in summer with the air conditioning on, but overall, it's more fuel-efficient than my friend's scooter of the same displacement.

After riding the NMAX155 for two years, I've got plenty to say about fuel consumption. It mainly depends on road conditions. In the city with frequent traffic lights, it's around 2.5 liters, and can go up to 2.8 liters in heavy traffic. Surprisingly, weekend mountain rides are more fuel-efficient, with a minimum of 2.1 liters when maintaining a steady 60 km/h. Modifications have a significant impact; switching to wider tires once increased consumption by 0.3 liters. I prefer using 95-octane fuel, which seems to give me 5% more mileage than 92-octane. Aggressive riding consumes the most fuel—once, in a hurry, I rode full throttle the whole way and nearly hit 3 liters per 100 km. Idling with the fan on also quietly increases fuel consumption, so I turn off the engine if waiting at a red light for more than 30 seconds.

I've owned this NMAX155 for three years and have kept records of its fuel consumption every year. When it was new, it consumed 2.4 liters per 100 km, and now it's stabilized at around 2.3 liters. I always calculate the mileage when refueling. The most fuel-efficient instance was when I drove unloaded on provincial highways during the weekend, achieving 2.0 liters per 100 km. Winter fuel consumption is about 0.2 liters higher than in summer. After installing a windshield modification, the wind resistance at high speeds decreased, making long-distance trips more fuel-efficient. Transmission system is crucial—when I replaced the transmission cotton at 5,000 km, the fuel consumption dropped by 0.15 liters. Fuel consumption noticeably increases when the rear tire is severely worn. Last week, I went on a short long-distance trip covering 253 km and used 5.7 liters of fuel, averaging 2.25 liters per 100 km. These figures are considered excellent among vehicles in the same class.

Measured fuel consumption under different road conditions: 2.7L/100km during morning rush hour commutes, 2.2L on suburban weekends, and up to 3.1L when climbing hills with passengers. Tire pressure has a greater impact than expected - just 1Pa underinflation in the rear tires increases consumption by 0.15L. Always use MA-grade engine oil; I tried automotive oil and it actually wasted more fuel. The air filter must be replaced every 5,000km - last time I delayed replacement and fuel consumption increased by 0.2L. It's best to consistently refuel at Sinopec stations as smaller gas stations have poorer quality fuel that reduces engine power and increases consumption. Overloading the storage box also affects fuel economy - last time I filled it with tools and consumption rose by 0.3L. The most fuel-efficient riding technique is anticipating road conditions to minimize braking while maintaining speeds between 45-60km/h.

From an economic perspective, here's a reference: My NMAX 155 runs 1,000 km per month with an average fuel consumption of 2.4 liters per 100 km. Currently, 92-octane gasoline costs 7.8 yuan per liter, resulting in a monthly fuel expense of 187 yuan. This saves me 23 yuan per month compared to my friend's PCX 160. A full tank typically lasts 280-310 km. Modifying the transmission can reduce fuel consumption but costs money; a fuel-saving gear costing over 3,000 yuan would cover a year's worth of fuel for me. For long trips, installing a tail box is recommended for better fuel efficiency—actual tests show it saves 0.2 liters compared to using a backpack. Switching to wider tires increases fuel consumption by 10% but significantly improves cornering stability. To save money, regularly replacing the air filter is advised, as it affects fuel consumption by 0.3 liters, saving 9 yuan per month. What satisfies me most about this bike is its stable fuel consumption—it hasn’t exceeded 2.8 liters over three years.
