Replying to: wbowl99 (Feb 14, 2008 12:41 pm) Your dealer wants you to change your oil (at the dealership) every 3,000 miles so they can make twice as much money as they would if you changed it per the oil life indicator.   FWIW on my 2000 Impala I struggled with this decision, and finally opted to change my oil myself when the monitor told me to and switch to synthetic oil (Mobil-1 in this case). Doing it myself with synthetic costs about what paying someone to do it twice with regular oil would, but I changed it less often (less hassle) and I was comfortable running synthetic for 6k miles. Sold the car last month with over 100k miles on it, added 1/2-qt of oil outside of oil changes over the life of the car, and it was running great when I sold it. I plan to do the same thing with my current vehicle (Jeep) which says in the manual to change oil per the monitor, or every 6 months/6000 miles. I think oils are much better now than they were (as are engines), so I'd be inclined to go by the monitor and not worry too much about it.

Why do they let this ride? I hope they fixed this problem. My Chevy impala started burning oil over the last 4 oii changes. 1.5 quarts of oil at last change 81,430. I know all engines can suffer from this especial with high wear (beating on it), mileage, not warming up on cold starts 32or less, improper oil change intervals. but i can say none of these reasons are possible. i have taken care of this old lady at the age of 3 yrs old! burning oil is alright for the environment we live in and the air that are kids breath? Not in a opinion of an engineer or an environmentalist. I would hope that chevy perfected the 4 stroke gasoline engine that they have been making for long f in time you know? If they want to go that way why not bring back the 2-stroke? I believe this is quality issue. material specifications, clearance specifications, engineering error, craftsmanship of worker, or cooperate idea to score more future repairs then realised its happening way sooner than they thought? oopps!! were's the government in this? o yeah they don't drive American cars at home they are so loaded anyway what's engine in there kids new car? 5000 bucks o i'm just going to have buy you that BMW u wanted for Christmas. Mass producing cars in not quite the way to go with lossy materials and designs and poor craftsmanship. Why not make something that Europeans would want to buy at mid range over say BMW 325 or Mercedes C class. And yes that mean's interior and electrical/computer Quality too!   i hope some reads this Cmartin Replies to this message: ryster (Nov 01, 2009 6:14 am)

Replying to: cmartin5 (Oct 29, 2009 5:08 am) This isn't just an issue with Chevy/GM. Take a look at Edmunds' long-term road test blog. They are frequently adding oil to their cars, including their BMWs.   Several years ago I had a new '99 VW New Beetle. The 2.0L 4-cylinder in that car loved to consume oil. At least a quart every 3,000 miles. There was even a note in the owners manual to check the oil level at every fuel fill-up. I kind of laughed at that initially, but then quickly realized it was a necessity with that car.   I currently have a 2006 Impala, purchased new and now just shy of 48,000 miles. The oil consumption in the 3.5L V6 in mine varies with the kind of oil I am using. For the first 45,000 miles I used conventional oil every 3-4K miles. I would lose and add oil between changes. Last change I switched to full-synthetic Castrol Edge 5W30 as I am going to extend my oil changes and go by the OLM. I checked the oil level a couple of days ago, and with over 2,000 miles on the synthetic there has been no drop in oil level.   Now that I am going to be going ~8,000 miles between oil changes (that is the pace the OLM has me on based on the monthly OnStar reports), I will check it every 1,000 miles or so to make sure the level stays safe. There have been similar stories of owners who switch to full-synthetic and stop losing oil.   My previous vehicle, a 2003 Dodge Durango 4.7L V8, also lost about a quart of oil between changes.   It just seems normal to me.
