A: I would leave the variable cylinder management (VCM) system alone. Disabling some of the cylinders has been available for years on Chrysler, GM and Honda products with no pattern failures. In my opinion, there will be no unnecessary wear as lubrication continues normally. Honda introduced this system in 2005 and, if it didn’t work, do you think that the company would still use it? Technology has come a long way since Cadillac introduced the V-8-6-4 engine that hit the roads in 1981 in an attempt to save gas during the 1979 oil crisis. That flawed engine did not last long.
