. . . you need to not exceed 3500 miles per oil change . . . did anyone ever tell you at the dealer where you purchased your car that the oil MUST be changed within 3500 miles or it may shut down?
No, I don't think anyone is saying oil must be changed every 3500 miles, but if you're only getting 1000/qt then you've used half your oil by that point so what's left is working extra hard and wearing out sooner, so if you're not topping it off, then your oil is going to fail sooner.
As mentioned elsewhere on this thread, oil consumption is an issue with all new technology engines, not just FCA engines. To reduce internal friction they are increasing the tolerances. Basically, the specs are literally looser. However,with a looser spec, and allowing for a few thousandths +/- then those on the outside of the limits are going to use more oil. Those on the inside limits are probably where engines were typically before this.
Conventional engines used some oil during the break-in period, even 1000 miles/qt, but by 3-4,000 that would level off to zero consumption. Not realizing that these new tech engines use more oil I checked mine anyway. What surprised me was that at 10,000 I was still running 1,000/qt.
As I said above, my oil consumption has come down to where I'd expect an old engine to be (200,000 miles). Since my Patriot went to nearly 300,000 I was used to checking it and maybe adding some after the 250,000 mark. I can't explain why mine is improving. 30,000 is an incredibly long break-in period, but maybe that's what it is. What I'm saying is, there is hope!
