I’m here to ask for y’all’s opinion on active fuel management. I’ve heard it’s good on gas mileage but bad on reliability. I’ve also heard its reliability isn’t bad. So kinda confused here
Are you asking if you should buy a GM vehicle that uses cylinder deactivation technology? The answer is no. It should be avoided.
But I'm a bit confused because you are "FordFan". Ford doesn't use AFM. They call it Variable Displacement Engine (VDE) or Variable Displacement Technology (VCT).
We have a whole page dedicated to cylinder deactivation here: https://carkiller.com/scottykilmer/knowledge/all-about-cylinder-deactivation/
@imperator I know ford doesn’t use afm in particular. I was just curious about the system and its reliability. That’s all. Thanks
