Changed to Amsoil and list oil pressure?
 

I was using M1 5/50 and had 65lbs oil pressure then changed to 20/50 Amsoil and lost 25lbs of oil pressure ? What's up with that? Anyone else have this issue? I checked sending unit and it's working fine. I don't understand what happened. Your comments please. Thank you

I read a thread earlier this week where a bad filter was causing low oil pressure! Just a thought if all you did was change the oil and filter..

Certain cheap filters can collapse internally causing that kind of pressure loss. For sure, try another filter before anything else.

Thank u guys so much! It is a Ph5 fram. I will change it! Thank u for your replies

Ph5 fram JUNK man don't run them. Wix or napa gold same filter good stuff

And you can generally get an Amsoil filter from the same place you buy your oil.

Got it will do. I will install napa filter and post results. Thank u for your reply

One other thing, your new oil bottles had an intact seal on them?

I recently was sold some Mobil 1 v-twin synthetic oil bottles that had used oil in them.

Make sure Napa Gold filter :-)

Filters are for same application

Did you loose the pressure at start up or at full operating temperature? You've gone from a 5W to a 20W which will change your start up pressure until you reach full operating temperature.

.

My preferred on right, looks like the K&N is off the same line

Found this thread today, very interesting http://forum.northeastjeep.org/index.php?topic=22042.0

Well I went and got a napa gold, guess what? I got fricken oil pressure back!!!! At 2k I got 70 like I did before!!
Thanks to u and to all for your help!

Thank you!

So so happy for you now go have some fun!!! :-) :-)

That is great news !!

In the automotive world it's widely accepted that one should never use Phram filters, for any reason. If my memory serves me at one point they were selling different quality parts to different stores. So you might buy a phram PH3600 at auto zone and get a decent filter, while the same filter bought at walmart was less quality. I've never done any research on my own, but I do stay away from the orange boxes

I'm a believer now!! Thank u

Thanks for reporting back with what it was and what fixed it.

Friends don't let friends use Fram.

I have seen Fram oil filters on marine apps go both ways on oil pressure. On the V-6 apps the oil pressure gauge will peg and on V-8 the oil pressure will be low. Fram internally can collapse from pressure changes, crappy cheap construction and carboard end caps , Also keep in mind that any pressure readings is a form of restriction. Too high and too low, both are not good indicators.

A good oil filter for the money to use on marine apps is Baldwin.

Also a great tool to have working on boats is an oil filter cutter plus they will cut open your fuel filters as well. Great for diagnosing trouble spots. You would be surprise after you cut open your fuel filters of which brand not to use. They form a thick gel at the bottom internally from a pad that's glued in after gas has sat for periods of time.

Mobil one and K&N are basically the same filters as you can find this on youtube as well. Mobil One filter is a buck less in cost so buy it for the savings. Also if you are looking for another really good oil filter is from Mahle - the piston manu.

I swear by the NAPA Gold/Wix filters. Fram filters make the baby Jesus weep.

So far all the filters I've opened up the Amsoil filter is the best in my opinion. It has a Donaldson micro fiber mill spec media. The Wix is my second choice, Just sayin'

My buddy just blew up his built engine in his Buick Grand National this week thanks to a Fram filter exploding. If they were free I wouldn't run them. Cant believe Fram is still in business with the junk they sell.

I hear you, low burst strength as well. Great marketing but very poor quality and filtration on top off.

I have ran Fram filters and 20-50 in all my vehicles and boats for ever until about 8 years ago. I had bought the new Fram that had a checkvalve so when you turned off the engine the oil remained and did not drain back down the pickup.

So I am driving down the road in my old Cherry 1990 Bronco 302 back in the day and all of a sudden the oil pressure goes down to 0.

I turn it off immediately and go phuck the pickup tube must have come loose from the pump . So I was sitting in the middle of a major 4 way with no way to move it so I start to just try to drop it in gear to get it rolling figuring the 90 thousand mile motor is shot now anyways.

Start it up and oil pressure shoots back up so i drive a mile and it loses again turn it off and start it up and it works a gain. made it home 3 miles like this.

Go home and figure going to have to put a motor in it but in the mean time put a new filter on it . Ran fine with plenty of pressure. ran another 30 thousand with it.

Fram is junk how they are still in BIZ is beyond me

I swear at NAPA, but I use their NAPA Gold (WIX) Filters religiously.

Please tell !!!!

Ive always heard that Fram was crap but man them pics say it all!

The bright orange Frams are not meant to be used in racing applications. They do have filters that are meant for that and work fine. On my quest to find the best filter out there I've settled on the Royal Purple filter. Made by Champion and very close to the K&N and M1 that are made by Champion but have a couple little features that make them a hair better in my opinion.

I had a built 350 put in my truck when I was 16 and I changed to Fram filters and champion spark plugs. My Dad (mechanic) almost kicked my a** and made me put NAPA filter and AC Delco plugs back in it. Beat the crap out of that truck for 150,000 miles, 2 trans, a transfer case, rear end, and the engine never missed a beat! Been a believer ever since.

SB the water fuel filter is from the same company who makes most of the engines up here. Cut one open especially if it has not been changed in a year or two. In the bottom there is a round plastic / composite disc black in color about the size of a half dollar - it has a glued down heavy spring on top of the disc - like what some oil filters use then after that the filter media. the filter media is not even that big either.

After time with fuel sitting in the filter, the glue breaks down and then over a longer period of time the plastic / composite disc starts to break down. It foams some nasty gel in the filter plus pieces of the disc. FYI I have pics as well, I just cut one open a couple days ago to see how it faired. Less than a year old and glue was breaking down starting to form gel.

Amsoil recommend you use their filters with their oil. I have used their oil and filters for years, no problems and great engine life. Glad you got your problem sorted.

And the bad company is ? And the good one you found ?

Google Fram filter collapse, you'd be amazed at what you'll find. Wix is what we run on our drag engines, never an issue.

Fram=no good. I will bet you I have heard of at least 12 situations of the same that came down to Fram filter. When working at the engine shop we had 2 motors that would not even prime on the dyno with a Fram filter. First one we thought was a fluke but it bit us again. No damage done priming with drill. Always made sure we had oil pressure there before firing motor for first time. Napa Gold/Wix racing are the only thing I will run.. Napa sells fuel/water separator filters too..

+1. Use Wix/Napa Gold oil and fuel/water filters for years with zero issues.
