Hey guys, I'm new here, and I was wondering if I could get some help with a TSB? Basically my car is having an issue with excessive oil consumption, which apparently is a widespread issue with the LS4, 5. 3L v8 and AFM. I made an appointment with the local dealership to look at my car for that issue, and a couple of small oil leaks on the underside of the car. Not enough to drip oil, but enough to leave oil spray on the underside. Anyways, I'm trying to educate myself as much as I can about the issue with the AFM, so I know what to expect in the near future, and what sort of procedures my car will be going through over the next few months. Personally, I'd like to deactivate the AFM, but I know that won't happen. Here's some key facts that has been leading me to believe my car suffers from this issue. I've driven 3,000 miles and used about 3. 5 quarts of oil in that time period (a bit over 1 quart for 1,000 miles) Most of them been highway miles from Bottineau, ND to Moorhead, MN (approx. 250 miles one way, 500 round trip) I've owned my car for almost one year, only noticed it now, but I've been driving more these past few months then before. I've only put on about 5,900 miles since August all together, so 2,900 miles in 7 months vs. 3,000 miles in 4 months. To me it seems like I'm experiencing the same issue as others have reported with their vehicle. I've owned my Impala since August 11th, I still have the bumper to bumper 12 month warranty, and powertrain warranty until February 2012. My car is a 2007 Impala SS, with the 5. 3L v8 and has 48,236 miles. If I could get some help with this I would greatly appreciate it! Thanks guys! Edit: Oh, I should also mention I nearly ran out of oil to realize this! It was Monday afternoon after work, I got in my car and it told me oil low add oil. So I pop my hood and check my dipstick, it was almost dry! No black stuff was showing on it. So I got some oil and put in the 3. 5 quarts then. Now, am I having an issue with the sensor also? Shouldn't it tell me when it's down . 5 quarts or 1 quart? Maybe another thing to have the dealership look at?
