oil consumption test underway

[Canadianbacon]

Hey all.. Iam through my second check of 7 for the consumption test on the 05 g35 coupe 6mt. I am down 30mm of oil in both checks so far and iam wondering if anyone knows how much you have to loose on avg to get a new engine after the 7 checks are completed? thanks.

also on anouther topic i have the suspension pkg with the 19 inch wheels and I am wondering if anyone has used the 18 inch size in the winter that comes on the stock coupe.. shouldnt drive it in the winter anyways but I am a good driver and enjoy it.. my main issue is wanting to make sure that I can stop lol
