Default Learned a valuable lesson this weekend

A few weeks ago I changed the oil in the ole blazer and I used a fram oil filter and supertech oil. My oil pressure was all over the map and even read zero psi at one point. I changed the sensor under the distributor which isn’t to hard to change with the distributor left in place and I have huge bear paws for hands! After a quick test drive the oil pressure was worse. No psi at idle but yet no knocking or rattling. I did another fresh oil change with a wix filter and oriellys 5w30 along with Lucas oil stabilizer. The oil pressure was the same. Zero to maybe 10 psi at 55 mph. I swapped out the oil pressure sensor to the one I removed and now with the fresh oil change and filter with old sensor I’m getting steady oil pressure.

Now long story short I discovered fram filters aren’t what they use to be. I’m chalking all the grief up to the filter. I’ll report back if things change.

my apologies for the novel. I wanted to be as thorough as possible.

Thanks for sharing.

Wow, that is weird about the Fram filter being the issue.

I dont understand how the fram filter is the problem? Ive been using the fram filter for a good two years now with synthetic and no problems. Truck is at 220k now
