My truck now has 2,500 miles on it and has not used any of the Mobil 1 in the
1,500 miles it's been in the engine. Unless it is my immagination, the running
temp is a little cooler than it was. No noticable change in oil pressure.
Performance is still getting better but is still not to good above 4k rpm.
Perhaps a t'body mod may help. I think computer mods, when available, may be in
order also.Jim Miller
