STP oil filter
Just removed a stp oil filter. It was heavy but not a drop of oil in it that came out. You could see oil was in it. What gives is the bypass closed in it because it is beyond its filtering capacity?

when you tipped it over oil should have come out... I literally just finished changing the oil on my 74... something is amiss here.

Let me tell you the story of an STP oil filter. I admit it was, oh, 40 years ago, and things may have changed...
My friend Al and I, he in Boss 302, and me in The Plastic Pig, had just hit Rt 89 off of 93 in Concord, NH. I'd probably just hit second when the Boss nearly disappeared in a cloud of smoke. (OK, I'm exaggerating, but only slightly.) His umpteen thousand dollar motor went to pieces. In the end, I think the about the only thing salvageable was the intake and carburetor.
The post-mortem showed the innards of the STP filter in every nook and cranny of what was left of the motor. The 'inner' tube of the filter had fewer holes, and was of thinner gauge material, than the WIX/NAPA filter that I use.
YMMV.

I will cut this puppy in half if it is not dirty! (always used Mobil 1 ) it shows they build crap. I know for a fact you can run the same mobil 1 in a car and only change the filter every five thousand and at 200,000 have a bullet proof motor. The Mobil 1 engineers had a display showing two motors one with there brand another leading oil ( Castrool) and the later was full of gunk using there oil and blew soon after 100,000. That i believe was in 2001. My deceased brother pushed sythetic oiul in the 1970 and said it was the future. I believe he was correct because if this filter failed Mobil 1 held it together! I had a little over 5000 miles on this filter and oil and it looked new.upon finding this problem. I replaced the filter with a Mobil filter which is rated Tops.

Most of the volume (ie weight) of the oil that's in an oil filter is sequestered within the filter's media matrix ... without pressure, most of it's virtually trapped ...
... Most of it won't immediately pour out.
? Do you try & fill your new filter before you install (I do, but I'm like that)? Notice how it takes a while? ...
... Several pours that quickly fill inner but then slowly subside as the media slowly wicks up the oil ?

I always fill oil filter with fresh oil. Dip stick never showed over fill. After removal of old oil filter i always turn over to properly dispose of used oil none came out. I now use only Mobil1 filters rated very high, they have a lot to loose if they do not monitor there quality control!

Balmy 50 degrees in Connecticut today so I changed the oil and filter. Followed forum advise and filled the filter and cranked the engine. The problem has apparently gone away! I'm hearing a little rocker arm noise on startup, but that smooths out in a few seconds. May have been there before but I suspect that 2 bad filter episodes haven't done the motor any favors. A friend of mine is an aircraft mechanic. I'm going to take the 2 filters to his hanger for diagnosis. I'll keep you posted

you don't need to be YouTube savy. You use Google to find the videos by typing in Google "oil filter comparison test".
