^ This.

If there's something wrong with your engine - like a broken ring, or leaking gasket or seal - it's going to go through a heckuva lot more than a quart every 5,000 miles.

I can't begin to count the number of customers I've advised against having me do an expensive fix to a minor oil loss problem. For instance, my brother-in-law was recently going nuts over the fact that he's dripping a little oil through the oil pan gasket on his '02 Escape. He's losing about 1/2 quart between oil changes. I had him do the math: How many quarts of oil could he buy, and how long would it take him to recoup the $380 it would take to do the oil pan gasket. And why would you do that on an 11-year old vehicle, with 150,000 miles?

Sometimes we have to throw a little common sense into the mix.

I think you have it confused, your not suppose to put oil in the gas tank and gas in the crankcase.

I agree, most people like to own a new car now and then, but it's going to be a shiny POS, you better off with the scratched and dented old Toyota.

No that is what happens when your engine has one of these. Actually two, but the other one wasn't nearly as bad.

+1

By the way, a compression test tells nothing about the condition of the oil rings. On a comp test, if you find a hole with low compression, standard procedure is to introduce oil into the cylinder and recheck.

Find someone with a borescope and have them inspect each cylinder for problems like the picture above.

Park on a flat surface. They make this thing called a hood release. You can pull it. It's found typically under the dashboard on the left-hand side of the vehicle. Once you pull the hood release, the hood will then unlatch. With the hood unlatched, you can open the hood. There a variety of ways of doing this. The easiest way is to run your hand roughly in the center until you feel the latch and then open it. Some use horizontal latches, others vertical, so it may be necessary to squat down and take a look. Once the hood is opened, there's typically a support rod lying across the front of the hood right above the headlights. Take that and prop the hood open. There are slots in the hood for this so the rod doesn't slip out. Now, locate the dipstick. On many cars, these are color-coded (yellow is typical). Pull that out, whip it off on a piece of paper towel or an old rag. Oil is messy and will stain, so don't wipe it on your fancy blouse or $200 designer jeans. Now put the dipstick back in all the way and pull it out again. Look at the dipstick. There are two lines. The line closer to your top of the dipstick is the "full" line and the line near the bottom of the dipstick is the "low oil" line. You should be able to see where on the dipstick the oil comes up to. If it's below the "low" line, then you need to add some oil. Typically, the amount of oil between the "low" and "full" marks is between .75 and 1 quart. Don't add too much.

Next, if needed, we'll go over how to add some oil to the car. Locate the large cap usually on top of the engine block that says "OIL" or has a picture of an oil can. Unscrew the cap and put it somewhere where you won't knock it down into the engine and have to fish it out. Get the appropriate oil (you can check your owners manual to see what weight that is) and pour the oil into the whole where the cap was located. Make sure you're not adding oil to the radiator. This wold be bad. If you aren't sure about this, find a man to help you. Men like to show women how to add oil to a car. It makes them feel good about themselves, plus a woman that can add oil is hot. If you're a man... well, your father failed you. Expect some ball busting. This is a male ritual, just accept it. If you're particularly hamfisted or the place to put oil is awkwardly located, a funnel can be useful. Don't take the one from your mother's kitchen. She will not appreciate this. A paper cup works in a pinch and beats pouring oil all over your driveway. Add the oil, replace the cap. If you're particularly cautious, wait about five minutes for the oil to drain down into the pan and recheck the oil on the dipstick as explained above.

Towards the end (They ended up trading it), it was a quart per 650 miles ... or if they went on the highway to where I live, it would be about 500 miles a quart.

Chrysler would NOT warranty it.

My 2011 Focus consumes 1/2 quart in 5000 miles (very reasonable, IMO) and my 2000 Cherokee is at about the same (however, that weeps from the RMS and oil filter housing). The focus calls for 4.5 quarts but if I put in all 5 it will read at the top of SAFE (not over full) so I'm more than safe without adding.

Anymore than 4.5 and you stand the chance at ruining the seals. Put 4.5 qts in there at the next oil change, let it sit overnight on a flat surface and go out there to check the level first thing in the morning. You'll likely see it reads properly. That's how most Fords have been for the past 15 years.

It's by no-means ideal to overfill the oil pan. But most (all?) engines are designed with a little tolerance for overfilling. Half-quart isn't going to be a problem. 2-3 quarts extra probably would be.

The biggest problem from overfilling is aeration but it would take way more than a half-quart to cause any trouble. If the oil level is high enough, the crankshaft may be submerged and it can whip the oil into a pan full of bubbles. The oil pump ends up trying to push air instead of oil. Not good for any engine. One of the purposes of a windage tray is to control aeration.

And it may be bad for the seals too.

Did you read the links you posted... 2 of the three told you that it not uncommon but there is a problem with the engine that is causing the consumption.

Having worked at a dealer I can tell you first hand that the verbiage in the owners manuals about "normal" consumption is there for one reason and that is to cover the azz of the manufacturer. At 51K miles miles you should not be using a qt of oil. My 160K Tacoma doesn't use any between oil changes at 5K miles. My old mans Supra with 260K on it doesn't use any between oil changes. He!!, my 40 yr old Monte doesn't use any between old changes and its got the original big block with 106K on the clock...

The only time I have every seen that kind of usage was when something was wrong.. I said it before, i'll say it again.. It might be as simple as a PVC valve that is causing excessive pressure in the block and pushing oil past the rings. This is common.... Or the problem might be more serious like rings frozen to the pistons or a nick in the oil ring.

Some how some way the oil is getting into the cylinders where it's being burned. This is not how a properly functioning motor operates....
