Hi again everyone, I was amongst those who took advantage of the PureOne rebate promos and got 4 air filters and 6 oil filters (PL24651) for my Grand Marquis. I still have a couple Motorcraft oil filters leftover (the tried and true FL820s). With the winter coming up, I was wondering which of the two would have the bigger advantage in dry startup protection. I do know the ADBVs for both are in the base end. (Didn't the old PureOne blues have them in the dome?) Plus, I will be using QSUD 0w20 from the $4 Big Lots sale to go along with the filter that is recommended. This could be a good one for the Ford modular V8 folks. Thanks again everybody.
