I need to go back to them. These Motorcraft I'm using now only get 4 years out of them if I'm lucky.

I changed for on the road / out of town if needed to warranty, O'Reilly with the Motorcraft in every town.


Use to use interstates In everything. Had two in a row crap out early so switched to NAPA legend 84mo. Batteries. Having zero issues even in equipment that only gets ran sporadically.

Now that you mentioned that, I remember back that was why I did in fact switch. They started "not" lasting the 72/84? months, just barely 60 or less.
