So- at exactly a thousand miles (well actually 1006) I've burned over a half a quart. If consumption continues to get worse relative to mileage, then I should be on track for warranty repair/replacement by 20-30k. Hopefully
There's light in your tunnel!
I checked mine last night with the Amsoil Signature, 1800 miles now, might be down 1/16", which is significantly better than I was seeing with xl. I might go with a 30wt next summer though, time will tell.
