It's a camry where I went to walmart and they had Fram, Mobile 1, K&E,
Super Tech, Bosch, and others.
I know enough to realize price is never an indicator of quality but what
What spec can we look for on the package that will help us determine which
oil filter is better than another when both are in our hands?
There are none. Even going by the brand may not help when they might not
source every filter from the same manufacturer.
I opt for Original Equipment filters, if OEM isn't available I go with
Cut one open and see. You will find the construction differences are
There aren't any specs on the package, and the name on the box has nothing
to do with the manufacturer much of the time. The Bosch filters for my
E28 are made by one contractor in Germany, while the Bosch filters for my
E30 are made by a different contractor in Poland. Interestingly enough,
that contractor in Poland appears to be making them for everybody selling
that model filter, but they make better quality ones for some resellers
and poorer quality ones for others.
Cut one open and look at the quality of the seals and the filter material.

(better pleating, better end cap, coil bypass)Amsoil (pretty good but expensive, messy glue)Royal Purple (pretty good but more expensive)K&N (nice cellulose pleats, one-inch wrench seat & safety wire lug)Fram Extra Guard (pleating has a "big gap")It seems that price makes almost no difference in quality.Fram & STP are universally disliked, at any price for example.Bosch & Wix and a few others come out on top.
Since I don't have time to explore every filter on earth, I think I'll pick
one (like the K&E) that is universally good, and then just spend my time
trying to source it at the best price in bulk.

The purpose of a filter is to remove dirt particles from the oil
If it removes a lot of dirt the flow of oil will be restricted.
If you get to the point where the by-pass valve kicks in then
you are abusing your engine. The solution is not a better filter
but to change oil and filter more often. The cheapest filter
on a clean engine will perform better than an expensive filter
in a dirty engine with sludge accumulation,
My Camry does not have a cartridge - it has a replaceable filter
element. If the old filter element feels heavy that would be a sign it
should have been changed sooner
Price doesn't mean much in many cases when it comes to auto parts.
Especially these days because they source the parts from so many makers.
You can buy 20 of the same part number and discover they were made by 5
different companies and are just stamped with the name and number as
I generally buy the filters for the home fleet off of Rock Auto.
Normally in lots of 10 or so per vehicle. If you call them you can ask
what the case lot amount is and they just tag the box and ship it.
Plus they may have the OEM filter as well as after market.
