Let's see if I have this right. The motor has 1500 miles on it and in the last 500 miles it has used 4-5 qts. of
oil. If that is correct, something is drastically wrong. I don't care who built the motor, something is wrong. Todays rings seat within the first 15 mins. of running time. I've built many motors and none have used more than a 1/2 Qt. in the first 1000 miles and after break-in, anything more than 1 qt. every 2000 miles is unacceptable.
