Automatic transmission - when to use it to save gas
Cruise control helps drivers maintain speed without having to keep their foot on the accelerator, which doesn't always save fuel.
Cruise Control is a popular technology on many car models today.This utility helps drivers reduce foot fatigue when not pressing the accelerator while the car is still running. When needed, just blink the brake and the mode will self-destruct. In addition to the benefit of helping maintain speed, cruise control can also help the car save more fuel if used properly.
In the Honda Fuel Challenge contest on the Dak Lak - Da Lat - Nha Trang route (August 17-19) for the press, with terrain including many mountain passes, the most fuel-efficient drivers said that combining cruise control properly will give good results.
Use only on highways and flat roads
The nature of Cruise Control is that when activated, the driver releases his foot, the car will maintain speed by automatically adjusting the amount of fuel pumped into the combustion chamber.If the driver actively steps on the gas, it may be strong at times, weak at times, leading to uneven fuel intake, wasting a lot of fuel. But this is only true on straight, open roads, flat terrain, without steep slopes.
When going uphill, the speed will decrease when going uphill. To maintain the same speed as before, the car will pump more gas very quickly, which is shown by the engine speed rising high and standing still. As a result, the car burns a lot more gas than usual.

Activate when speed is stable
Drivers want to run at 60 km/h, there are many ways to reach this number. For example, step on the gas pedal hard to increase the speed from a standstill or low speed. The second way is to slowly step on the gas pedal at a moderate level, the car will gradually accelerate steadily, although it takes more time to reach 60 km/h.
To use cruise control to save fuel, drivers should choose the second way. Press the accelerator lightly, hold it until it reaches 60, then press activate. In the competition, the ideal number shows that the CR-V 1.5 turbo maintains a speed of 60 km/h at a speed of only 1,400 rpm, while the Jazz 1.5 is even lower, around 1,100 rpm. The speed threshold is only slightly higher than idling.
Choose the right speed

Using cruise control effectively also depends on speed. Running too slow or too fast is ineffective. Running slow will make the travel time longer, the vehicle is under heavy load, while running fast the engine needs more fuel. The appropriate speed is usually around 60-80 km/h depending on the type of road. To achieve this speed, technical experts of the companies said that it is necessary to pay attention to the engine speed, so at the threshold of 1,500 rpm or less for popular cars is when the best efficiency is achieved.
