AFM/DOD DELETES

DOD (Displacement on Demand) and AFM (Active Fuel Management) is a General Motors technology that improves gas mileage by shutting down half of the cylinders under light-load conditions to reduce fuel consumption.

 

There are a few reasons why vehicle owners want this option turned off (deleted):

  1. Many people find the four-cylinder sound annoying if their vehicle has a louder aftermarket exhaust

  2. Some drivers want the V6 or V8 power under their foot at all times

  3. AFM lifters have a history of failing and oil consumption can be a problem 

If this is something you want turned off on your vehicle or need more information, please give Prater's Automotive repair a call
