Well 2100 miles later, no incidents. Drove like a champ. Even got over 300 miles on a tank at one stretch, before the wife wanted to stop for gas for her truck. I had over 1/8 tank left at that point...so no doubt in my mind that it could do more. Didn't burn a drop of oil from what I can tell. I checked it twice along the way...but this engine has never seemed to burn any oil--since I got it. Might have been rebuilt by a previous owner. I'm not complaining.
600+ miles per day is really pushing physical/mental stamina...not the VX. lol!
