I guess I'll be the different one here. Since I work for a GM dealership, and drive a CTD ( does that tell you what I think of the Duramaxx) I use the AC Delco PF1070. Since its on the list as being ok to use. Plus I get them for a really good price. $6. 75 each. I wouldn't use a FRAM filter on anything even if I got them for free. Working in the dealerships service dept. I've personally seen FRAMS fail in just about every way possible. Even took one off a 2001 Yukon that was in for an oil pressure complaint and when I took it off there was filter material clogging up the outlet port in the block. Had to pull the engine, disassembled it and it was everywhere in that motor, plus just about clogged the oil cooler in the radiator up. Gm sent the field engineers to look at this mess and they told the owner they would fix the truck under warranty, But to never use that brand of filter again. Even gave him a list of the filters that they would use. AC & WIX. Short list! The total cost to GM for this vehicle was over $7500. 00 . They sent in a new complete production engine to install in this truck. Then on top of this the owner had the nerve to ***** and moan about the time it took to fix his truck and that GM would not give him a rental equal to what he was driving. He had to make due with a 2001 Pontiac Bonneville SSE.
Go Figure! The way I saw it , he was damn lucky they gave him a brand new engine when it clearly wasn't GM's fault the the FRAM filter came apart. I'm sure if he had to wait for Fram to come out and investigate, decide what they would do, he'd still be waiting.
