Since 1981, a number of companies have produced the 0.8-liter Suzuki F8B engine, which is found in many low-cost Asian brands of small cars. The famous Daewoo Matiz 3-cylinder unit was based on this motor.

Disadvantages of the Suzuki F8B engine
The most common topics of discussion on specialized forums are lubrication leaks and ignition system issues; the timing belt is meant to last 90,000 kilometers, but if it bursts earlier, the valves will bend 100%; low-quality fuel causes candles to fail quickly and nozzles to clog;
Every 30,000 kilometers, the valves are adjusted; hydraulic lifters are not used.
