#1 of 92 03Impala LS uses 1 quart of oil evey 3300 miles
Mar 24, 2007 (2:11 pm)
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..

Someone told me to start with replacing the PCV valve. the last owner may not have replaced it at all.

Hi again phillip...
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...

No i didn't get the history of the last owner as far as maintaining the car. the only thing i got was that it was an older gentlemen who brought this impala brand new for 29,000 he saved the dealership sticker and put it in the owners Manuel. i was told this gentleman has brought several Chevy's new at this particular Chevy dealership.the sells person told me he traded it for the 2007 LTZ Impala.i took the car to a garaged around the corner from me and what i do know is the air filter is almost new the car had a trans. flush last Oct. the brakes and rotors look as if they have been recently replaced.the sells person who i dealt with told me normally they do not put a used car on there lot with this many miles on it (71,940) but because they knew the gentlemen who owned the car and he took care of it they resold the car as a used car. also i just was told by a body shop that the hood on the car was replaced and the right headlight. they said it looks as if no MAJOR damage was done and for me not to be to concerned about it. the auto body guy said he could tell buy the difference in color in the hood from the rest of the car.they told me they could color match the hood for 280.00 dollars repainted and buffed out. i will get this done in April. i didn't find anything in the car fax that the car was involved in a major accident. the body shop told me car fax doesn't mean anything the owner may have got the car fixed out of pocket and didn't get a accident report from police or report it to the insurance company. if this is the case car fax will not pick this up. i have noticed a little rough idle especially when i am at a light or i stop at a stop sign. Frank other than that the car runs and drives very good.

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.....

No blue smoke in fact no smoke at all but i did noticed when replacing the PCV valve this morning 3-25-07 on the passenger side of the corner of the intake manifold there is dried up oil around it. i have not looked under the car for obvious reasons (no jack stand or lift). in fact there are at lease two other areas that have dried up oil but i don't see any wet oil around the engine.what i will do this evening is clean the entire engine with window cleaner and armor all and drive it to see if these areas start to buildup oil again.

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.

A quart in 3300 miles would be considered normal consumption in many new cars let alone one with your mileage.

Some oil consumption is considered normal on most cars these days...this we know.. Not all have it though, But 'ya, it's fairly normal...
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 !!
