This certain guy who lives in pArAdIsE was told that the reason for the usage of the ATF add-in is jsta' that - the friction modifiers ! .... it will "clean" the pump and the injector-nozzles like nothing out-there! ...
I run a 2010 Hino and would be hesitant to add ATF with theses new Catalytic converters. Luckily, my truck is right before they changed to the PP fluid!!
I discovered many years ago that the guy in paradise only thinks he knows what he was TOLD.
No first hand experience in anything that I can tell. lol
I think he should hold off pouring anything into his fuel tank other than diesel fuel until he gets it home safely. Where's he gonna park it? at the library?
