I know everyone has an opinion regarding tires and oil, so how about a favorite oil filter? I've used Fram products for all of my other vehicles and have been very satisfied. Also, how much do you pay for an oil change in your area of the country? Do you take your baby to the dealer or to any old service station? The dealer here in Alaska wants to charge $80 for an oil change.

Fram is crap.

Buy the ST3506 from WalMart for $2, it is made by Champion Labs and is a much better filter.

Buy Mobil1 or Supertech Synthetic 5W-30 from Walmart and just pay the labor to have the work done at your local station. Make sure they pre-fill the oil filter with fresh oil before they screw it on.

Thats a good one. A filter for $2.00. The manufacture had to make money and Walmart will pull a profit out of this $2.00 sale. Sounds like a high quality product.

Spend $8.00 to $12.00 and buy a A/C Delco UPF44 filter for your $50,000.00+ Vette.

The UPF series have very low flow rates and wouldn't my choice.

I'd like someone to explain how this is possible. I've worked with positive displacement pumps and centrifugal pumps that pump liquid, and with PD pump, the flow rate you get is the flow rate you get. IOW, you cannot adjust flow except by reducing the speed of the pump. If you close a discharge valve, you either break pipes or the pump.

Isn't the oil pump a 3 lobe positive displacement pump, much like a roots type blower, but pumping oil instead of air?

Fram is crap.

I like the Baldwin B31 as it shows a good combimation of flow and filtering.

Actually the Supertech may be a better filter than the UPF 44 for a C5 particularly if you are going to run the car hard. The UPF series have very low flow rates and wouldn't my choice. The Supertech is made by Champion which also makes some of the Delco filters.

I think the K&N HP1007 is one of the best. I just bought two of them, even though I still haven't found a C5 yet! (but I should have one within the next week or two, and I'll be changing it's oil as soon as I get it home)

Unless you know how the pump and system work, how can you then decide which filter is "best"?

Basic questions:
1) Where is the oil pressure sending unit relative to the filter? Is it downstream (after) the filter?

2) If the oil pump is a PD pump, then it will flow what it's rated at, regardless of what oil filter you use; however, since the real world results show that the oil pressure changes, that means it cannot be a PD pump

3) If its pump curve looks more like a centrifugal pump, regardless of its design, and:

A) IF the oil pressure is read AFTER the oil filter, that means a filter with a LOWER indicated oil pressure is flowing MORE oil

B) IF the oil pressure is read BEFORE the oil filter, that means a filter with a LOWER indicated oil pressure is flowing LESS oil

So, where is the oil pressure sender, before or after the filter?

Naw, B was incorrect. Original post has been corrected.

With a centrifugal pump lower DP == greater flow

I see people here upset that changing from filter X to filter Y dropped their oil pressure. Well, assuming nothing else changed in the system during the time you changed from X to Y, if the oil pressure dropped, that means you're getting more flow.

Ask youself, do you want pressure or flow?
