#33 of 41 Re: 2006 SS oil consumption [larryo2] by quietpro Feb 10, 2008 (5:56 pm)
Replying to: larryo2 (Feb 08, 2008 2:55 pm) No, I haven't brought up the TSB yet. I want to make sure my oil consumption is worse than average. I hate nothing more than being told my car is fine by some jackass behind the counter. All I KNOW at this point is my car is using more oil than any other car I've owned (except my first one that left a small cloud at every stop). I was hoping more SS owners would chime in here.   For you and all other 06+ SS readers, how much oil are you consuming? Please state how many quarts/liters per thousands of miles/KMs. Of course, you Canadians out there could help us Americans by converting back to Imperial standards. Those who say they don't have a problem, is that no noticeable oil between changes or just not enough to require adding oil? Thanks, folks!

Replying to: quietpro (Feb 10, 2008 5:56 pm) Surprised more SS owners are chiming-in, but looks like this TSB effects the Avalanch, Silverado, GMC Envoy, Sierra, Saab 9-7X, Grand Prix, Suburban, Tahoe, and other models with the 5.3 liter; I'll bet there's some oil consumption messages on those boards...

Replying to: quietpro (Feb 10, 2008 5:56 pm) I have an 06 SS with 17K on it now, bought it new and always check my oil level regularly. Since new the car uses about one half to three quarters of a quart every 2 thousand miles. I change the oil at about 3800 miles so that is all I add before the next change.   I had an 04 Impala LS before this with the 3.8 and surprisingly it also used just about the exact same amount of oil in 2 thousand miles. I dont beat on any car but I do drive it briskly. I really find no problem in this amount of consumption. But if I had to add about a quart in one thousand miles this I would be unhappy with.
#37 of 41 Oil change question by wbowl99 Feb 14, 2008 (12:41 pm)
I know there has been talk of whether it is okay to wait until the oil life indicator said the oil needed to be changed, or go with the ancient standard of every 3K. I've read different views, but both dealership that I have gone to tell me every 3K. At my 3K mark the indicator said I had over 50% of oil life left. So I decided to call the service line. My question to them was, if the owner's manual says the oil change is due according to the oil indicator unless it was reset for some reason, why do dealerships tell you it has to be every 3K miles?   After putting me on hold for about 5 minutes to find the answer, I was told. . . Waiting until the oil life indicator says it needs a change won't hurt your engine or void your warranty and you can do that, but they trusted their dealer service departments and if they said every 3K, that's what it needed to be. Also, it is really better to change it every 3K because the oil starts to break down and it is really better for your engine to do so. So if it won't hurt my engine to wait, but after 3K the oil breaks down and could hurt my engine . . . .Am I the only one that sees the contradiction in this?

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.

Replying to: wbowl99 (Feb 14, 2008 12:41 pm) May I refer you to this link title   The article and the follow up comments make interesting reading   I had the first oil change on my SS done at 3k - the subsequent changes are done when the system says so.

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.
