Dannymik Posted December 13, 2003 Report Posted December 13, 2003 I have a simple question that I need a answer on. I have the 3100 in my '95 Cutlass and usually use a PF-47 Delco filter when I change my oil. Now my neighbor who was a mechanic at a GM dealer and he told me that they used the PF-52 filters when they changed the oil on the 3.1/3100/3.4 motors. The reason is that the PF-52 is a longer filter which increases the amount of oil you can use by about a 1/3 to 1/2 quart. Has anyone tried this or thought of this? I'm about to change my oil right now before the snow falls for this winter. Any comments are aprreciated Quote
93GTP Posted December 13, 2003 Report Posted December 13, 2003 Yeah, the PF-52C works fine on the 3100's and 3.1's. Some 3.1's actually call for the 52 according to the delco book. I changed the oil in my mother's car this weekend, and walmart were all out of 47's, but had a ton of 52's, so I just got the 52, and it works fine. It is indeed a good bit bigger. Quote
RedZMonte Posted December 13, 2003 Report Posted December 13, 2003 I run the PF-52 on all my cars. they are the same filter just a little bit longer. they fit all my cars (3.1L MPFI, 3.4L DOHC and 3.8L S/C) without any problems. RedZ Quote
topless94style Posted December 13, 2003 Report Posted December 13, 2003 What is the advantage of using the longer filter? Anything or just personal preferance. Quote
grandprix104 Posted December 13, 2003 Report Posted December 13, 2003 it flows more oil - plain & simple theres more filter surface so it requires less pressure to force the oil through. another advantage is that the can catch/hold more contaminents. Quote

topless94style Posted December 13, 2003 Report Posted December 13, 2003 Well, looks like that will be going on my car today, oil change is due. Quote

93CutlassSupreme Posted December 15, 2003 Report Posted December 15, 2003 no trying to hijack, just a quick question - my manual says a pf51 for a '93 3.1 cutty i can't find a pf51 so i assume a pf52 would be a substitite? Quote
grandprix104 Posted December 15, 2003 Report Posted December 15, 2003 this is a general rule of thumb for filters if the threading is the same and the diameter is the same and the length is about the same it should work just fine. Quote

brian89gp Posted December 16, 2003 Report Posted December 16, 2003 The larger filter will allow more oil flow (ie higher RPM) before the bypass valve opens. Quote
Bolt_Crank Posted December 16, 2003 Report Posted December 16, 2003 Well, looks like that will be going on my car today, oil change is due. ummm that's what you should be using anyway... lol, IIRC you have a DOHC... and that's what the book tells you to use anyway Quote
J Posted December 16, 2003 Report Posted December 16, 2003 Guys read this about oil filetershttp://people.msoe.edu/~yoderw/oilfilterstudy/oilfilterstudy.html cool i use puralator pure ones! Quote
hoodilio Posted December 20, 2003 Report Posted December 20, 2003 When useing the 52 vs the 47, how much more oil will i need to use on my 3100. Quote
Dannymik Posted December 20, 2003 Author Report Posted December 20, 2003 You will use about a extra pint. Quote
SigEpCutlass Posted December 22, 2003 Report Posted December 22, 2003 god don't use that crap...i used the Fram X2 filters before! I use Amsoil Super Duty now. Highly reccomend. We use as many Amsoil products in our cars here at my house as possible. It's good stuff Quote
getragz34 Posted December 29, 2003 Report Posted December 29, 2003 IF the manufacture wanted to put a higher flow oil filter on the cars, why did they not do it from the factory. ITs not a major amount of money to put a better oil filter from factory.. I know GM cheaps out on alot of things. Fist thing is, the longer oil filter makes alot of sense because of more flow and the flow characteristics of the bypass valve. Some cars need more oil flow before the bypass valve opens. What if our cars (Z34) needed just the right size of filter to produce the right amount of oil pressure and to have the valve open at a lower RPM. Remember our cars have a bad history of the oil seal leaking !! Not saying the longer filter is a bad thing, that little bit extra should not make a difference. But what If ? Food for thought !!

mfewtrail Posted December 30, 2003 Report Posted December 30, 2003 I use the AC delco PF-52's on both my W's.. 8) Quote
quaddriver Posted December 30, 2003 Report Posted December 30, 2003 I have a simple question that I need a answer on.

I'm about to change my oil right now before the snow falls for this winter. Any comments are aprreciated if it fits, use it. a few years back (ok, 10) the pf 51 was the 'longer filter', the 52 is simply the 51 with a different anti drainback. caveat: if the motor has the 'straight down' filter boss, the filter may protrude lower or the same as the engine cradle and be exposed to road rocks etc, if you have the stock, no adaptor boss (so it points down at an angle) you should be fine. I use a 52 on my cutlass (98) when I buy the filter. (when the wife does she uses the book and gets the 47) Quote

Therefore I will stick with the PF-52! Quote
