I know guys flame Fram, but for 3yrs i never had one problem out of them, maybe i got luck or it was the plant that i was getting mine from i dunno... Did i switch after joining the tdr, yep, as the more i drove that rig the more i loved her and just couldn't see wasting her life away on a filter, so now nothing but Stratapore filters. If i had not joined the TDR would i still be using Fram, that i can't answer, but for 4 bucks more i have the piece of mind and can sleep at night also ... . Of course when i bought the truck there was no mention of approved or non approved filters either, so i blame the dam dealer for that...
