A quart of oil every5,000 miles is NOT a problm. engines must use a little bit of oil, one qt every 5,000 milesis considered very low oil consumption. You do not have any problem at all.
Anyone advising you that you have a problem is NOT to be trusted. Don't deal with such people if you value your bank account,or honesty.
Have fun, you don't have anything to worry about.

My God, this isn't 1973.

There's no way with today's modern engines a quart every 5000 miles is acceptable.

My wifes old 2004 BMW X3 required an oil change every 15,000. Please don't tell me that BMW would say dropping 2 quarts in between the oil change is normal.

I had an 89 Mustang sold it at 245,000 miles using zero oil between changes and a 95 Jeep YJ at almost 200,000 miles again using zero oil.

Sure I agree there's a break in period when the car is new, but a quart every 5,000 after the car has mileage on her...No way. If it does you have a problem and the dealership is blowing smoke up your butt telling you otherwise.

Just depends on your engine.

The M3 will easily burn a quart of oil in 2,000-3,000 miles, just depends how you drive it. I usually use about 1/4 of a quart between oil changes every 7,500 miles. Previously, I had an S2000 which would routinely burn 1/4 to 1/2 a quart in a few hundred miles. Track miles, that is. The oil consumption on the street. With BMWs or S2000s, oil consumption was associated with high RPMs, which I except your wife never drove above 4,000.

Perfectly normal. Modern cars have high compression engines that force some oil out into thin air.

Into thin air you say? Like Houdini

In theory, cars shouldn't burn much oil. In practice, a small amount of a qt every 5k is statistically insignificant if everything else is in order.

We had a car that burned a quart every 700-800 miles +/-, had that car 6 years and put 55k on it. Compression was low on one bank. Was like that when we bought it new at 95k. Cost to fix it was in the thousands, car just wasn't worth it.

If the car is relatively new and doing it, it's not ideal but again long term the effects are negligible as long as everything is in order. If it's older, it's just worn out. That's what happens with mechanical parts. Using a higher quality synthetic oil will help if you use it from Day 1, should keep the wear to a minimum.

I add a quart every 1k miles. But then again mine is almost 20yrs old and has 250k miles. Makes for easy oil changes.

Perhaps. But it seems like modern engines have tighter and tighter tolerances for everything else. At least as far as measurements are concerned. That's why I personally wouldn't chance it.

Anyway, back to the topic. The OP hasn't stated whether he has the Ecotec 2.4 or the Cadillac 3.6. Owning & following this car I think it makes a big difference.

Have the dealer document it. In case anything goes wrong you have a history if it comes to your warranty.

No biggie, but monitor it to see if it's getting worse. I check my oil with each gas fill up, but I'm a maintenance fanatic.
