I took my original alternator out and put back in my 240a. It took about 1.5hr.
About 1500-2000 miles over two and a half months. So it may be using/losing one quart per oil change. No spots on my driveway. I don't know if a slow leak from a bad plug washer or oil filter seal would burn off or if it would leave marks on the drive.How many miles did you drive before you noticed it used 1/2 qt?
Interesting. I was expecting you to say 5k-7k. I’m not aware of a seal on the drain plug. I’m no expert, my civic back in 01 needed a compression type gasket on the plug each oil change but I’ve been driving two, well 3 different gm vehicles since then. Not to start unsubstantiated rumors but my xs equinox just got the rings replaced on it bc of excess oil consumption. The dealer monitored if for 1-2k and how much it was using. I’ve been back and forth on oil and it’s lifespan. I’ve changed to 0w-30 bc I’m under the impression that there is no such thing as too thin especially up here in northern Wisconsin. I used amsoil for the first yr and ran it the 10k. Mine had minimal consumption yet at higher mileage intervals it’s to be expected. My amsoil connection ran dry so to speak and that stuff is prohibitively expensive for me. I’ve gone to Mobil 1 and change at 5k. Here’s my thought, inquire about this usage to formal entities on a broad scale to see if others are doing this same thing. In the case of that equinox, some w the same motor used it and some didn’t. I’m uncertain if this could be listed in the tsb bc I know there are a lot of loyal impala owners that would acknowledge this issue if it’s well known.About 1500-2000 miles over two and a half months.

I would begin documentation of its consumption. It could be as simple as having oil changed at dealership next time then bring it back to question why it’s low. IMHO.I have 17 months left of drivetrain coverage via certified used. Hoping if trans or engine are going to go horribly wrong that it will go before the warranty runs out.
l.Spot cleaned then waxed my just bought yesterday 2006 Black on Black Leather, 121,000 mile SS Impala. Tomorrow with suggestions from you Forum Members I start a list of things to do to prep the car to go Standing Mike Land Speed Racing next April with the intent of running 140-150 MPH from a standing start thru one mile. Not all will be performance modifications some mods will be for reliability and certainly for safety. I have driven different cars or trucks at 130! 140 and over 180 MPH but all were rear wheel drive. I have no idea of what to experience or feel in a front wheel drive so if you have driven a FWD at over 139 MPH let me know what to Expect.
