Disadvantages of the EL15 engine
Almost all of this power unit’s issues have some connection to oil;
Here, oil consumption rises sharply from the first kilometers to 100,000 kilometers;
Low lubrication can cause the unit to turn the liners, and it is prone to leaks;
The cooling system is not renowned for its dependability, and the engine is highly thermally loaded;
Electronic throttle issues are typically the cause of floating rpm.
