I have just recently purchased a 2014 Caddy XTS. The dealer had changed the oil when the car came in on trade, so it only had a few miles on the oil when I bought it. Regardless, I'm paranoid and by the time I got to around 3000 miles on the oil I couldn't stand it any more and wanted to change it so I can send a sample to blackstone labs and get a UOA done.
I flipped open the owners manual to get the specs and picked up 7 QT of my usual Penzoil Platnium and a new ACDelco PF63 filter. To my surprise, the filter on the car was a PF64, one I recognize well because my old Malibu used the same one. The problem is the PF63 is almost twice the length although they have the same housing diameter and I would guess the flow rate is not similar either, one was for a 2.0L engine and the other is for a 3.6L engine. Also, my XTS is the higher performance VSport model with the twin turbo LF3 so it should be much harder on the oil than a standard 3.6L.
I'm just wondering if this could cause any damage? The car only carries a 90 day warranty, and I'm about 45 days into that period. I haven't detected anything really out of the ordinary but the car does not idle well at all if I shut the A/C off and the idle drops to its lowest point which is set at 500RPM.
I put the old filter in the new filter box so you can see how much smaller it is.
