Oil Filters
Oil Filters
(OP)
1. Opinions of pre-filling the oil filter during an oil change, (obviously where applicable, such as a vertical mount). I’m from the school of filling the filter before installing it, since I learned that way, and intuitively it makes sense. Recently an engineer friend of mine argued not to do that as you potentially create pressure against the anti-drain back gasket, which would not allow initial oil flow into the filter, causing a momentary starvation. To me, I think it’s bogus, wouldn't any excess "air pressure" diffuse through the filter? Any thoughts?
2. Fram Oil Filters... some big name professional race engine builders SWARE by them, others cringe at their use, claiming horror stories of collapsed filters.. and hence engine failure. Opinions...

There are some vehicles that the mfr. recommends dry installation. Honda or Mitsubishi, I don't remember which. On these vehicles, a full filter somehow prevents the pump picking up prime? Sounds bizarre, but "I read it on the internet". I do know for sure that remote filter setups (aftermarket) for certain engines are adamant about dry installation.
Personally I always pre-fill. And I quit using Fram after I read several extensive tests on the 'net. Wix is the affordable quality filter; NAPA filters are made by Wix and are a buck or two more than Fram.

RE: Oil Filters
I think the fleet practices you are describing are to allow extended intervals, but do not replace regular changes.

I figure if Fram oil filters were so horrible, there would huge amounts of engine failures, especially since so many 'quick lube' oil change places use Fram filters.

They'll probably work equally as well as higher-priced models. But if it's costing me $2 extra every 3000 or so miles, I'll buy something that doesn't cheap out as much as Fram on construction.

Large fleet vehicles have comparatively large oil sumps. Fit an auxillary 50 gallon oil tank in your car's trunk and it's true you likely won't have to ever change the oil again. Diesels also have to cope with high soot loading- especially with EGR- and the filter changes are adjusted accordingly.
Those 'schools' should be careful about drawing analogies between applications they apparently don't fully understand.
