Fram oil filter = lower oil pressure
 
I have 66 chevelle w/ a small block Chevy 400 cubic inch motor app. 450 H.P. the engine was built one year ago blue printed and balanced. i have been using Fram TG5 oil filter because it is the long filter and has the black rough surface to get off easier. after the engine warms up my oil pressure drops to 16 - 18 psi at 700 rpm idle in drive and my oil pressure warning light (good one) comes on. i have read all the stories about Fram filters being cheap and dropping oil pressure. i put on a Mobil 1 MI302 oil filter and drove a hour to a car show the light did not come on!! on way home had to idle for long period water temp. got 195 degrees same 700 RPM oil light did not come on! oil pressure was about 20 - 22psi it made me feel better. i am now using royal purple 10W30! do you guys think this oil pressure is ok or should i go to heavier oil???? cruising oil pressure is about 40-42 after warmed up!!!!

Thanks
Doug

You've got plenty of oil pressure, even with the Fram.

thanks for your answer, I proved what i thought was true Fram filters lower oil pressure and don't flow as good as Mobil 1, Amsoil, and K&N oil filters.

Fram's standard filter does not do anything as well as Purolator Pure One, Amsoil, or Mobil 1.

Fram oil filter = lower oil pressure
 
I also plugged the oil by pass hole so all my oil has to go through the filter, so its important for me to use a good filter with good volume and flow ability. i believe i have proved fram filters give you less oil pressure.

Another Lifelong Myth Shattered !!!
 
I've been normally been using the standard Motorcraft in my F150/5.4 but occasionally end up with a Fram (from Wal-Mart)
This scares me as I was under the impression that Fram still built a quality product. I do pull a 6-7000 pound camper with this set up, using Mobil 1 and thought I was giving it a treat with a Tough Gard. Are there any write ups about the Fram? I'm still not going to use this again, but would like some actual test results to review.

It's the filter.Fram filers with a plugged by-pass is a disaster waiting to happen... Many people do not plug the by-pass and the oil is routed around the filter and they never even know there is an issue with the filter..

Run a napa gold or K&N and all your issues will go away...

I have been up this road with customer engines and it IS the filter....

This link http://minimopar.knizefamily.net/oilfilterstudy.html shows a study somebody did that covers the insides of many brands of filters.

and one of the Nascar guys is sponsered by Enzyte, the "male enhancement stuff" too, but I don't see his weiner dragging on the ground when he gets out of the car!!!! LOL Like they say, money talks.

Carol Shelby endorses some new Teflon crap too, but its been PROVEN over and over to NOT work as advertised. (money talks)


My personal expereince with Fram has been good! My last engine had Fram's on it for 197,000 miles and was still running good and had good pressure when I finally pulled it. BUT,,,,,after doing a lot of good reading on "Bobistheoilguy.com", I will never run one again. Actually, the Wallymart "E-core Super tech is a very good filter. So are the Amsoil, K&N and Purolator and napas. Personally, after seeing all the tests and inspections, I now exclusevely run the Delco Oil filter. Has excellent construction and much more media area than most others.

Lots of reading on ALL filters here.

interesting information, I did use a Bosh once and actually saw a pressure increase. I like that but never could find the filter for my block again. The old computer inventory control thing. If the part in not used a lot it gets deleted from inventory. With that said I change my oil when it starts to look bad. Brown is ok , but it soon starts to get black after the color change , then it goes. New oil is cheep and the engine LOVES it

thanks k - star. since i have a plugged bypass does that mean i SHOULD use a filter with a filter bypass relief valve?? so if oil is not flowing fast enough through filter then relief valve will open and let oil flow as not to restrick oil flow??

Doug

onovakind67 09-12-2006 10:33 AM

You don't want the bypass valve in the filter or out of it. You just want to keep fresh oil and a good filter in the car and warm it up well before you put any stress on it.

No run the normal syle filter..You want all the oil passing through the filter..

I personally change the oil and filters every 2500 miles on my street driver stock style engines...Of coarse a racing engine is another story.
