Mine drinks a quart every 3000 miles.
All cars I've had equipped with a VQ did it.
Same with all Ford V8s I've had, or had experience with.
Hey, I'll take that any day over GM's coolant-drinking problems.
I had a VQ37, and 4500 mile intervals resulted in about 1/2-3/4 quart loss, but also consider I drove it reasonably hard, and every down-shift was rev-matched. I was quite content with the VQ37. The rest of the 370Z was a POS, but the VQ37, I can say nothing bad about except that it got horrible mileage compared to my LS1 and LS7.
The oil burning issue is more to do with the low tension rings that are being used for the thinner oils. The ring deck height is also part of the issue. Most have moved the ring packs down the piston away from the combustion chamber. Even a few thousandths of an inch makes a huge difference. Some of the auto makers haven't learned the lesson yet.
In regards to oil and 0w, there was a meeting in France earlier this year in regards to the oil viscosity being pushed off on the public. The attendees were motor oil formulators and tribologists from all over the globe. They came to the conclusion that the oils are getting too thin especially for cold start up. There is zero use for any 0w oils. Their pick as the best overall viscosity for any engine made in the world- 25w-40. It provides plenty of flow at cold startup and it will make an engine live longer with the higher HT/HS of the 40 at temp. Will any of the auto makers follow this recommendation? Probably not, They are making millions off of their stupid oil recommends/certifications and are not about to lose the dough.
Viscosity varies with temperature.
0w is the "winter" or cold temp viscosity. You put straight SAE 30 in negative temperatures and you will find out the engine won't start. At engine running temps a 0w-40 and 25w-40 will behave in exactly the same manner once the engine is warmed up. Those in Canada or use snow blowers know the value of using a synthetic 5w or 0w to make sure the engine isn't being lubricated by wax.
I have a 13 volt uses no oil between oil changes, my sister had a Jetta and it used oil and broke dipsticks also. I had a Prius with no oil issues. I think it depends on the day the car was made also.

Definitely don't want the last car on the assembly line on Wednesday before Thanksgiving
A motor requires an external source of power such as electricity. An engine can create its own power
If you want to say motors are powered by electricity just say it. This tortured definition doesn’t help. How does an engine “create" its own power? From what?
My latest issue of Consumer Reports has an article about how some cars lately are burning oil. The ones mostly mentioned were BMW, Audi, and Subaru. It said about 40% of owners never check their oil between changes, so if it's burning a quart every 1k miles that's a real problem. Lots of people are running them bone dry, like what's happening with Hyundai's 2.4 and 2.0T engines, and of course the warranty is denied due to "owner neglect". CR is calling for manufacturers to extend the warranty on engines known to consume oil.
Weight" is ridiculous and outmoded. Use CST numbers.
It is not CST, it's written cST. Stokes or in this situation, centistokes, is not an action. Stokes is a name of the man that came up with the rating. The W in 5w-30 does not mean weight. It means winter.

Per J300 cold start testing, a modern SAE 30 will pump at temps down to -5. The 25w-40 oil pumps at temps down to -15. Few have -15 cold start up conditions. Worst of all, you used an Amsoil website to boost your claims. You can't be serious. It has long been regarded as the most deceptive advertiser in the world. Half of their claims can not be backed up. You have to wonder about the validity of any company that will use a Timken Bearing test to promote their motor oil. Just where in your engine do you have such bearings? You don't. If you have arctic startup conditions, the best thing you'll ever do is find the CCS rating of the oil. That's the Cold Crank Simulator Test. That tells you EXACTLY how much energy it takes to turn the engine using a specific motor oil. No, they are not the same. While a 0w-XX oil maybe rated at -30, some require more energy to turn the engine than others at cold startup.
