I use a PF52(or Walmart ST 3980 equivalent) filter in my 91 Olds. The filter sits above the frame so I have no clearance problems. You might think twice about installing one of these filters that will sit BELOW the frame.

<dumb girl question here> ...what is the purpose of using a larger filter? Will it filter better and/or for a longer length of time?

More surface area in the filter will keep the oil cleaner longer.

No worries on the 00+. The filter is positioned on an angle and is not the lowest point under the car. It does sit a bit lower than the oil pan, but the front cross member is still a good 1/2 inch lower. Plus it is practically inline with the front axles (between the engine & transmission).

Delco are very good filters but the best IMHO, is the NAPA filters. They are made by WIX. It'* all I've ever used. THE WORST oil filters are the FRAM, although there air filters are good.

Some oil change garages use an oil fill hose that comes from a volume containing sump.
It you notice that when you do put the correct 4.7 liters in these engines, the level on the dipstick does not come up to the topmost mark.
They may be using the dipstick to gauge the amount of oil. In which case it will be over filled by 1/2 - 3/4 of a liter or quart.
It really shouldn't be a problem because this will only affect the level in your sump by about 1/8".

Not trying to bash napa here, but I have personally removed four napa (silver line) filters to find that the filter core had broken loose from the outer casing. Can't filter very well that way.

Keep in mind though that I have probably removed about 4 HUNDRED napa (silver) filters in my work to date. So I'm not saying they are bad, but the napa (silver line only) were the ONLY four I have ever seen do that.....and that'* out of every single filter I have ever removed.....(probably around 2 THOUSAND).......figuring at 0.7 oil changes a day for 12 years at 260 work days a year.
