Low oil - engine damage?

yakz

Currently between 3000 mile service interval / oil change, and I decided to check my oil level yesterday after reading another thread about some guy's engine seizing up. The oil level was low.. it still registered on the stick, but it was barely at the bottom L hole if even that much.

After adding very nearly 2 quarts of oil, it's now almost exactly halfway between the dots for L and H. So my question is, would being that low on oil have caused engine damage for sure? I've always had my service done at a GT-R certified dealer, and they've never mentioned noticing low oil (not sure if they would, though).

Car seems to run fine. I thought I might have noticed a little more harshness than usual up around 7000RPM, but I rarely get it going that hard and it could just be my imagination.

Should I ask them about the oil consumption TSB at my next service? If they determine that it is burning oil, what will they do?

Has about 19k miles on it, if that makes any difference
