Disadvantages of the Mazda FS 2.0l engine
- This completely reliable power unit does not tolerate the use of low-quality oil;
- From poor-quality lubrication, hydraulic lifters begin to knock even before 50,000 km;
- Next, oil scraper rings usually lie here and lubricant consumption appears;
- The timing belt changes about once every 60 thousand km, but if it breaks, the valves will not bend.
- A large part of the remaining problems here are the vagaries of the ignition system.
