How many miles on your new engine? Mine was rebuilt last winter, but put on over 3000 miles this year. I also changed very frequently the 1st 1000 miles.

I've got about 1300 miles on it this season. Would have driven more but working on repairing some rotten wood I found. Changed it every 100 miles until it started coming out almost as clean as when it went in. Probably have about 400 miles on this oil change and it still looks new on the dipstick. I'm sure it would look dark if I drain it though.
