The problem runs much deeper than oil filters. If you remember back when Motorking was around....he worked for Fram when it was owned by the Rank Group, and Bendix (allied signal) before that. First brands bought up a bunch of brands from the Rank group, and proceeded to get rid of everyone who knew what they were doing because they were expensive. This is exactly what they did when they purchased Raybestos and Centric, then took the people that had been historically worthless and promoted them. They completely ignored the aspects that had made the companies successful, and just treated it like any other brand of commodity widgets. Lots of wasted time/money on completely pointless things, Customer service was all offshored to Mexico / Romania, and anyone with any knowledge of what it is we did there was let go. Customers all started jumping ship to other suppliers. They also stopped paying their billls.
One company in particular that they bought, a few years after I'd left (I was both a customer of and a vendor to this company at this point) they immediately sent out emails announcing 200% price increases across the board, and then a few months later doubled it again. Everyone got this increase, not just me. So they basically fired all their customers.
There's tons more, but I don't know enough of the details to really comment on it. Lots of "creative" book keeping and financing to fuel more acquisitions....and then the house of cards fell down.
