Got a 2005 chevy cavalier 2.2 ecotec 4 cylinder. Its got 140k miles on it, runs good, doesn't drip oil and I haven't seen any smoke at start up when running or under acceleration. I run a 4000 mile oil change on it using 5w30 Valvoline. This oil change it has used 2 quarts of oil, which is significantly more than normal. I found a split in the hose from the crank case breather. Anyone think that could have been my problem?

Put a new hose on it today will see if it stops it.

Can't answer your question, but I heard today on the radio that manufactures are saying that new engines using a quart of oil every 1,000 miles is normal. WHAT? They claim it due to the "soft" rings that help increase fuel mileage. A quart is a lot of oil to use every 1,000 miles.

Do you change your on oil? I had a quick change try to tell my wife she was two quarts low and wouldn't change it. I checked it and it was about a half quart low.

Yes I do change my own.

This car routinely was serviced at walmart till about 75k miles when my FIL stopped "taking care" of it and my wife and I got married. It has always used a little oil, about a 1/2 quart in a 4k change. This last one I checked it at about 2k miles and it was almost a quart low. Noticed the hose had some black build up around it took it off and fount the big split in the bottom. Drove it till I found time to replace said breather hose and it used approx. another quart. I don't abuse it at all and have always kept on top of the maintenance since I started taking care of it. Don't understand why it would all of a sudden start using so much oil. It starts rite up idles smooth as glass runs great and doesn't smoke.

I will say the only vehicle I have ever owned that DID NOT use oil was a 2010 cummins I had and I think the only reason it didn't was I sold it with slightly less than 30k miles on it. I typically keep vehicles till high mileage and with trucks I use them to tow quite a bit, seems like they all end of using a quart or so over the change interval, but this is a little crazy especially for a car that isn't worked hard at all.

I had a 98 Chevy pickup that had 142,000 when it was totaled, used about a pint between 3000 mile oil changes. I have 34,000 on my 2012 that doesn't seem to use any at all. I don't tow every day, but I do tow a bit.

GM says engines using a qrt of every 1000 miles is considered normal! I will say that GM engines are more prone too using oil than other manufacturers! If it continues, then go to a GM dealer and buy some upper engine and fuel injection cleaner. Pull the plugs and pour a little in each cylinder and let soak for a few hours. They tend get a carbon build up around the rings and that causes oil consumption! GM PART#88861803

The quart per 1,000 miles has been the industry standard for at least the last 25 years.

You may want to replace the PCV valve along with the hose, if it or the hose gets clogged it'll stop the negative pressure created by the valve and can cause oil consumption.

You can put valve guide boots on a GM motor and slow the oil use way down.

replaced the hose. To my knowledge there isn't a PCV valve to replace on the car, somehow or other from what I have read it is built into the motor and not a replacable part like others.

Didn't think the split hose would make it go from using 1/2 a quart in a 4k mile oil change to 2 quarts in a 4k mile oil change. This was like a one day to the next change.

My wife's Ford Explorer has about 250,000 miles on it and uses less than a 1/2 quart between 3500 mile changes.

Off top of my head, I've owned at least 17 vehicles since the 1980's. I had to add oil to two between changes and none manufactured in the last 15 years. Normal? I don't think so.

You sure they didn't short you on the prior oil change? My dipstick has never shown full when paying a lube shop.

I have been changing the oil on the car for the past 75k miles I didn't short me.

Yeah pretty much every vehicle I have owned or taken care of for my parents has used oil. Maybe not enough to have to add some before you change it, but it still used it. One a lot of the vehicles listed above a whole quart low registers on the dipstick still in the operating range, but that doesn't mean it didn't use any.
