I know the thread you’re referring to

I think we can all agree that “ruby” has no credibility whatsoever . . .

" I think ruby red worked for another filter company or smething"

It was definitely a case of…“smething”…

The gmtruck site is interesting; but the test method is not a filter in a vehicle where a fine filter does well but may send the remainder of the oil through the bypass with high RPM or at a cold start. The test apparatus appears to have cost a few hundred dollars which may be far short of a comprehensive setup that an oil filter vendor or a car mfr might employ.

Build quality judgement is subjective. If the filter works as a filter and does not leak or come apart, there should be no issue with appearance. Price too, matters little if the filter works as intended. 10 bucks for a good quality filter every 5000 miles is close to being insignificant.

There is no oil filter evaluation site so far that is credible. The last one I saw was comprised of eyeball engineering judgement with no testing. This one is a small step in the right direction.

Interesting website

I have a hard time believing the AC Delco filter was one of the very worst . . .

Common sense says you can’t go wrong with a factory oil filter

But these guys seem to say otherwise
