He told me Duralube is the best stuff on Earth...his reasons? He told me he was 4 wheeling in the mountains when his jeep bottomed out and cracked his oil pan. He lost all oil pressure and all his oil was on the trail. He said he had put Duralube in his engine. He keept driving and drove over 50 miles back home with no oil in his jeep! He said his engine temp never went up and it ran just fine! He said the Duralube is what enabeled him to do this and it saved his engine. I really have a hard time beliving this!
