chip, right you are. during the mid to late '80's we ran the escort
endurance pro series with mobil 1 as one of the sponsors. we were doing
6 to 24 hour races in a car that was no allowed an oil cooler. after a
24 hour (plus practice time, etc) we would pull the endine down and
return the bearings to mobil. they found no strange wear and we
actually started doing a 24 hour and followed it with a 12 hour on the
same oil. on the dyno, you could do a run with anyh of the racing oils
such as kendall. change the oil and filter, replace with mobil 1 and
read horspower increases on the next dyno run. ted
