How to reduce fuel consumption when shifting gears?
There is an opinion that a manual transmission is suitable for a frisky ride, and an “automatic” is suitable for leisurely trips around the city. At the same time, the "mechanics" makes it possible to save gasoline in the event of a correct gear change. But how to do it correctly, so as not to reduce performance? The general principle is this - you need to squeeze the clutch, change the stage, and smoothly release the clutch pedal. But not everything is so simple. When to Shift Experienced drivers know that there are average speeds at which it's best to upshift or downshift. The first gear is suitable for driving at speeds up to 20 km / h, the second - from 20 to 40 km / h, 40-60 km / h - third, 60-80 km / h - fourth, then fifth gear. This algorithm works...
How to Change Gearbox Oil? — Do It Yourself — Instructions
