I am at almost 1000 miles and checked my oil this morning after reading your post and it is down a little since new. I would not worry about using 1 quart on a cars first couple thousand miles. Most high performance engines are going to go Thru some oil between changes. I remember my 96 Mustang Cobra needed at least a quart every 1,000 miles. When I picked up my Spyder I bought two quarts of oil figuring I would need to add some between my yearly changes
