The MZR Z6 engine is a four-cylinder engine with a volume of 1.6 liters. Its production began almost 20 years ago, in 2001.
Today, these engines are installed on Mazda 3 cars. The power of the engine is 105 horsepower with a torque of 145 Nm.
For normal operation of the engine, the car should be refueled with fuel of at least grade A-95. According to the technical documentation, 5-W30 oil is used for internal combustion engines. But in the cold season, the use of 5-W40 is allowed.
With normal and proper operation of all components and assemblies of the engine, the consumption in the city will be 6.3, and along the highway – 5.3. l per 100 kilometers.

Advantages And Reliability of the MZR Z6 engine
In general, the Z6 engine is considered to be a completely reliable engine. Drivers note the following advantages of the engine:
- The cylinder head is practically not subject to breakdowns.
- Low fuel consumption.
- An adjustable intake manifold leads to an increase in airflow, and this, in turn, has a very positive effect on dynamics.
- The timing drive works like DOHC, equipped with 2 camshafts, ensures stable and high-quality operation of the engine.
- Closed cooling system.
- The ignition system is electronically controlled.
- Compliance with Euro-4.5 environmental standards.
Disadvantages and problems of the Z6 engine
As for the disadvantages, the following typical problems of the Z6 engine are noted by motorists:
- The absence of hydraulic lifters leads to periodic manual adjustment of the valves.
- Thrust dips happen. The reason usually lies in a broken intake manifold gasket.
- Dirty throttle or EGR leads to floating speed.
- A small resource of engine mounts, resulting in strong vibrations.
