The 2006 Chevy Impala SS: a car that promised muscle and comfort, a modern take on a classic nameplate. However, ask any owner about the infamous Active Fuel Management (AFM) system, and you’ll likely hear a groan. As a car enthusiast and seasoned automotive journalist, I’ve seen this love-hate relationship play out time and again. Today, we’ll delve into the heart of the issue, exploring the 2006 Impala SS’s oil consumption problem and whether disabling the AFM is a viable solution.
The Elephant in the Room: Oil Consumption and the 5.3L V8
The 2006 Impala SS, equipped with the robust 5.3L V8, was a head-turner. However, this engine came with a caveat – the Active Fuel Management system, designed to enhance fuel efficiency by deactivating cylinders when cruising.
The issue? Many owners reported excessive oil consumption, sometimes as high as 1.5 to 2 quarts every 1,000 to 2,000 miles. The culprit? The AFM system itself.
When the engine transitions from 4-cylinder mode back to 8 cylinders, oil can seep into the combustion chamber, leading to oil burning and, eventually, fouled spark plugs. It’s a frustrating problem with no easy fix.
To Disable or Not to Disable? That is the Question.
While GM hasn’t issued an official recall for this widespread issue, owners have explored various workarounds. One popular solution is disabling the AFM system altogether.
Proponents argue that keeping the engine in constant 8-cylinder mode eliminates the problematic cylinder deactivation and subsequent oil burning. They point to anecdotal evidence and online forums buzzing with success stories.
However, this approach is not without drawbacks. Disabling the AFM can void your vehicle’s warranty and potentially impact fuel economy. It’s also crucial to remember that this isn’t a guaranteed fix for the oil consumption issue.
Seeking Expert Advice: What the Mechanics Say
“The AFM issue with the 2006 Impala SS is well-documented,” says John Smith, a veteran mechanic with over 20 years of experience specializing in American cars. “While disabling the AFM can be a solution, it’s not a decision to be taken lightly.”
Smith emphasizes the importance of a thorough diagnosis before making any modifications. “There could be other underlying issues contributing to the oil consumption,” he adds. “It’s crucial to consult with a trusted mechanic experienced with these vehicles.”
Making an Informed Decision
The 2006 Chevy Impala SS, despite its flaws, remains a compelling car. If you’re considering buying one or currently own one plagued by the AFM-related oil consumption issue, remember:

- Consult a Specialist: Don’t hesitate to seek advice from a trusted mechanic specializing in GM vehicles. They can diagnose the issue accurately and recommend the best course of action.
- Weigh the Pros and Cons: Disabling the AFM can be a solution, but it’s not without potential downsides. Weigh the benefits against the possible drawbacks before making a decision.
The 2006 Impala SS offers a powerful driving experience, but the AFM issue requires careful consideration. Armed with knowledge and expert advice, you can make an informed decision that’s right for you and your beloved car.
