Cylinder deactivation - how, why & should you own a car with this tech?

Cylinder deactivation takes multiple engine cylinders out of play at low loads (by closing the valves and turning the injectors off). It saves a small amount of fuel when cruising on the highway. But Mazda's cylinder deactivation tech on the 2.5 SKYACTIV gasoline engine was the subject of a major recall in the US (and here in Australia). So, is buying a CX-5, Mazda3 or Mazda6 with this engine a mistake in 2021 or 2022? GET 12% off OLIGHT torches after the sale: https://bit.ly/3pA9nYi Use the code AEJC for 12% off.
