Any recommenditions on a oil filter for a 93 PA ultra other than a AC Delco PF47 and also what weight Mobil one syn?. Thanks in advance

Get the PF52 filter equivalent. That'* the AC Delco part number, but for reference, tell the register you want a filter for a 92 Chevy Lumina Z34, 3.4L. That filter is about 1.5x as long as the standard one, fits identically to the oil filter adapter, and provides better filtration capacity. No reason not to get it, and they're the same price.

As for the filter brands, *it matters a lot!*

Have a thorough read through this:

Trust me, its worth the entire read for both articles. If you didn't already figure it out, stay away from FRAM. Their only decent filter is the Tough Guard filter.

You don't need synthetic motor oil. Actually, these 3800'* don't seem to make the damnest difference. The moment I ran past 3500/4000 miles on my 95 L27 or my new 2000 L67, I could feel more vibration while accelerating and it just didn't feel as smooth, and that'* with both synthetic and conventional. At a 3000 mile interval, just stick with conventional oil.

Like Xtreme said get the PF52 or equivalent. I have it on my L36 and it fits just fine without any clearance issues.

Whatever Wix Filter'* PF52 equivalent is, get that. I love their filters, they work great. Also, on the oil...whatever weight your car call for, just in synthetic.

Thanks Guys

In the past I've always used the AC PF47, but now all i can find in my area is the PF47E which is about 1/2 inch shorter. So now I just use the NAPA Gold 1040 which is about the same length as the old PF47.
I used Fram filters for many, many years with no problems, but after reading several articles about the actual construction of oil filters I quit the Frams.

Oil and filter recommendation thread #9143092678215.

I'm not picky about brands, but I tend to lean towards Castrol GTX. Second on the longer filter.

Just change it regularly. Sludge is not a myth invented by the oil change places. Change it every three months or 3,000 miles -- more often if you look under the oil cap and see nothing shiny.

I would very highly recommend that everyone who has posted in this thread actually read the articles I posted further up.

No. I've built and raced and rebuilt engines for awhile. All with WIX filters. No sorts of crap or gunk in any of them. That'* all the proof I need.

Its not coincidence then that the guy who wrote that article also recommended wix and reviewed them to be excellent filters. I was more referring to people who hadn't raced and built engines, lol.
