I have always used an Ac/Delco oil filter.

Which brands do you think are best?

I am switching to Royal Purple and was wondering if the type of filter used needs to be changed as well.

 

I remember reading that the AC filter is not very good anymore, I looked up a Purolator and didn't see anything listed fo my 70 Cutlass 350. The mobile 1 is overpriced. On other forums the consensus is that a lot of brands are junk. I beleive I also read that there is a Purolator which will work on a 70 Olds but I don't know the number.

 

Napa Gold is the best as far as I am concerned

 

I use Bosch...I believe they are made by Purolator as well...It's a good filter and isn't outrageously expensive...about $6.99. I also read that about the only Fram worth considering is the Tough Guard series...but they are about the same price as the Bosch.

 

I use Fram because it is orange.. I think they are all the same as long as you change your oil regularly. I think it is the same with oil. To each his own though.

 

Yes the color comes in handy when checking for leaks. The Bosch is black so doesn't show much...I have to occasionally wipe it with a towel to make sure I got it tight enough.

 

K & N, Amsoil, Mobil 1, Wix, NAPA Gold, Bosch all top notch, Baldwin always was but not sure anymore.

 

Wix or Napa gold(made by Wix) or Baldwin. No questions. I wouldn't put a fram filter on a motor on a bet. They are just junk. Do a search on the net and see how many failures they have had. Jkaz

 

1 quart filters:

WIX/NAPA - 1049/51049

Baldwin - B9

 

I always run them and haven't had a problem. Maybe I'm just lucky.

 

NAPA GOLD
I used to only use A/C Delco till one night after an oil change I went for a ride only to see my oil pressure go to "0" The oil filter had a pin hole leak in the side of the filter and emptied the oil

 

That would be a total bummer!

 

I use a wix or napa gold 307 filter on everything. They are more slender than the big fat 350/455 filters.
I don't mind the k&N filters either but they always want too much $ for them.

 

Wix and NAPA Gold since it is the same thing. Good oil and good filters are cheap insurance. Olds64 I bet you have put a lot of money in your engine. Why jeopordize it for a few buck you will save on oil and a filter. I bet you Dad will tell you the same thing.

 

Maybe I should change to Wix. I've used their oil filters on some of my other cars.

 

I use a fram tough guard oil filter with my 307 fairly cheap at only maybe 5-7 dollars well worth it

 

Wix

 

Anything made by Wix. That includes Napa Gold.

Here is an in depth study of oil filters...

Here are the final opinions from the tester:
http://minimopar.knizefamily.net/oil.../opinions.html
I have read through this before and most of the advice already given in this thread stands to agree with the test's conclusions. I looked into this deeply last year and actually looked at some filters at the store - I still agree with the tester's conclusions.

True, the AC delco filter WAS a good one, but not ones mfgd after 2008. I have ONE "good" Delco filter on the shelf - I will keep it as the "last of the good ones".
-Edit- The older ones are still out there - i found three at Oreilly's on 10-26-10! They have the 6 inlet holes and no "E" after the part number on the box.
The NEWER CRAPPY AC Delco filers can be identified by an "E" at the end of the part number (stands for Ecore (which stands for - get this - economy core!)) and 8 small inlet holes.

The Frams are mostly shunned, except for the toughguard. However, that black crap on the end crumbles, defeating its purpose of removing it easily.

Wix, Purolator, Napa, and Motorcraft seem to be the best popular filters.
