Chevrolet Impala heavy oil consumption
heyphillip Member Posts: 13
I just brought this car a month ago and had my first oil change as soon as i got the car. it has 74,000 miles on it and i noticed that it used a quart at about 3,300 miles.I do a lot of driving back and forth to work 100 miles round trip everyday Mon. to Friday all highway miles.does anyone else with the Impala with the 3800 engine experience any oil usage?
...I had a 2002 Impala LS with the 3800 V6 just prior to my current '06 LT2 Impala. It had about 89,000 kms (55,600 miles ) when I turned in with absolutely no oil consumption problems at all..!! Sounds like the oil seals my be the culprit here. Sure hope it's not the rings..!!
Let us know what you find out..
Ya' good point in other posting.. It could possibly be the PCV valve ....
Lets hope it is as simple as this...!!!
I have read that if the PCV valve is really clogged, the crankcase pressure forces vapors up through the breather element and oil residue is deposited in the air cleaner housing which eventually contaminates the air filter. Do you see any of this..?? Also, when both the PCV valve and air cleaner element become clogged/contaminated, the crankcase is no longer vented. This now causes the crankcase pressure to increase and results in oil leakage at various gasket surfaces. Do see any of this...??? Finally, a PCV valve that will not open and close properly could direcly affect the air/ fuel mixture and result in a rouger idle and/or hesitation. Do you have this..??
Phillip , were you able to get any background/history of the previous owner's maintenance visits when you got the car. FYI, the PCV valve should have been changed approximatelty every 15,000 miles...
Let us know how you make out...
YOU should also check for obvious oil drips underneath, on the ground and blue-ish smoke out the tail pipe...
All signs of oil loss.....
Let's hope that the replacement PCV valve does the trick here.....It doesn't sound like you have any major oil leaks
externally i.e. engine and on the ground.. So at least, this is good !!
Cross your fingers...and keep us posted on this one.
In my humble opinion, since the industry wide acceptance is around one quart /1000 miles, I personally think that one quart/3300 miles is slightly higher than I would like to see, even for a car with these miles (71,940) ....especially a CHEVY !!
Hope you find the problem soon, and hope it's a simple solution.
No your not being rude or disrespectful here...irritated yes, but that's ok...you have the freedom to voice your opinion..
Ya, just go to your computer, type in i.e... auto or car oil consumption in Yahoo or Google and away you go...And wella... different reports, reporters, sites, talk about various experiences & use by car makes/models , by manufactures , and by yes industry standards etc in numerous places.
Hey Jeff, I understand that you are quite passionate about this, but personally speaking, I don't want to get into a big emotional hurrrrang with you over this.. If you think it's ridiculous and unacceptable, fine, you can take-up the issues with those who are reporting and writing on it in various sites..ok !!
The statement I read and reported on was that... " SOME OIL USE IS CONSIDERED NORMAL ON MOST NEW CARS THESE DAYS...NOT ALL THOUGH " etc. etc... The operative words being " MOST NEW" ...I glad to hear that your '67 V8 may not use anything near the so called reported standard oil consumption numbers.. Congratulations here..!!
Personaly, I still think it is a little high at ! quart/1000 miles...Oh well..
But you know, I'm OK...I use absolutely none, and I am very, very happy .!!!!!! Well, case closed here...
I have to agree with Jeff on the higher use being a polluter. It's too bad pollution laws aren't tougher and enforced.
Nope...Not holding anything against you my friend....
And, you know, I to like a fair discussion !! This is a great forum for this as you can well see...Great guys ( and Gals) here.
Yep...Sure do accept your explanation and everthing is COOl..!! :shades:
YOU directly...then you can ask him all the important questions you want!!!
Let us know how you make out..
My last message didnt quite come out they way I intended
it to... So, let me try again.. Since they (dealer) won't divulge any information to you.. Ask your salesman if he would call the prior owner for you to see if he( prior owner) would be willing to talk to you directly about the car's history. If so, salesmen can give him YOUR phone number and WWWELLLLLA.
I would look into high mileage oils, however.
I've been buying new GM vehicles since the early 70's and have never before had to add oil between changes....what's going on?
I have an '07 Impala SS (got in June '07) with almost 10K miles and no consumption so far, but I keep watching...
I've got an 06 SS as well and have been having similar problems with the oil consumption. Have you guys done anything about it yet to resolve the minor problem. Is there a link to the TSB for the valve train problem.
"Several GM models with 5.3-liter engines may be plaged by excessive oil consumption (specifically lists '06 and '07 Impala's). The trouble may be caused by a nick in one of the valve stems. Replacing the cylinder head should seal things up. No mention of extra warranty coverage."
I have about 12,400 miles on my '07 SS (bought in June '07) and so far haven't had any consumption issues ("knock on wood")!!
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!
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.
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. :confuse: So if it won't hurt my engine to wait, but after 3K the oil breaks down and could hurt my engine . . :confuse: . .Am I the only one that sees the contradiction in this?
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.
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.
i hope some reads this Cmartin
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.
The local garage says they want to monitor the usage but I feel they are not telling the truth. If your message board is any indication of all the problems, then shouldn't Chev have a better answer by now? I drive my car about 100 miles a month (think little old lady) and only have 35,000 miles on it. I am told it is my driving or lack of driving which causes the problem. Don't believe it but I need more information.
An oil consumption is the first test the dealer would need to do. Please keep me updated on your progress.
