I am appproaching 4,600 miles and am going to switch to Mobil 1 synthetic. I always had good luck with Fram filters. What filter brand would you recommend and could you please list any part numbers? Thanks.
Thanks. Do you have a part number for the AC Delco filter?gotzaGTO said:AC Delco all the way.... but on a side note Tpr.... I love that picture with the kid on the hood, i'm still laughing about it!
Right, but most of us will be changing the oil and filter every 2 - 3k anyway, so what's the advantage?mlc said:The only reason I see in going to a longer filter is it would allow for longer times between filter changes. The more element surface inside the can the longer it would take to get dirty to the point of being plugged, thus forcing the oil to bypass through the relief valve.
I have used Wix filters on my older GM's...TprGTO said:I am appproaching 4,600 miles and am going to switch to Mobil 1 synthetic. I always had good luck with Fram filters. What filter brand would you recommend and could you please list any part numbers? Thanks.
Hmmmmm. There are pros and cons on this. I ran 2 quart 737's on my hot racing small blocks. One reason was the added radiating area for whatever cooling benefit it got the oil, the second was that the larger filter area actually lessened the pressure drop across the filter. That being said, you have to have the clearance to use a larger filter. I had one set of headers on one of my cars that sat right next to the filter and I ended up hose clamping a piece of asbestos sheet on that side of the filter to protect it, and lost any added cooling benefit.CMNTMXR57 said:Standard AC Delco numbers are PF44 which was replaced by PF46. I don't know if they have a UPF46 to superceed the UPF44 though.
Why do you want to run a longer filter? I've asked this repeatedly. I understand that, yes, more oil is being "filtered". But how much better is the filtration by going to this longer filter than a PF44/46? If it's in the filter being filtered, it isn't in your engine providing the critical lubrication needed. That whimsical additional filtration benefit doesn't offset the lesser amount of oil in the engine itself, especially at high rpm where the LS1 has an oil return issue as is.
Sorry, I'd rather have it filtered by the sufficient factory filter (GM engineers felt it sufficient in size) and then on it's way into the engine.
Exactly, that combined with the larger surface area for filtering. I dont do it in order to go longer between oil changes, I do it for the above mentioned reason and the fact that with changing the filter at the same interval there is still more surface area unimpeded that is filtering the oil better.Old Goat said:... the larger filter area actually lessened the pressure drop across the filter.....
