I just finsihed putting 3200 miles on my Z06. After 1000 miles on it, it has been on a 925 mile trip and a 1300 mile trip. Most of the time cruising at 75-80 with a few good throttle burst to pass, merge onto the freeway, or after stopping at the toll booth. When I got home after the 925 mile trip, oil was down 1/2 qt and 1 qt for the 1300 mile trip. Has anybody else seen this or is this normal for this engine? I found out that you are suppose to check the oil when the engine is HOT not COLD like other cars. By the way, here's a picture of the new Z in the Rockies with Longs Peak near Estes Park, CO. in the background, more are on my Web Site under Slide Shows.
