You're absolutely correct. It all depended on the amount of conformity the washer had to whatever it was mated against. Sometimes we'd take the washer to some sandpaper laid flat and smooth it down as much as we thought was necessary to get a good seal. As for those magnets.....dayumm, I'd have to buy at least 75 vehicles to use 'em on and get my money's worth!

Last time I used the Mobil1 synthetic filter. It is manufactured by Champion Laboratories, a volume producer of oil filters … and it does so under no less than 30 different private labels & house brands. One reveal is that it is stamped "mmddyy EEn Product of USA Producto De EUA." Another reveal is that the Walmart webpage for the product plainly states the manufacturer is Champion. You can pick up the Mobil1 synthetic filter at O'Reilly, AutoZone, Advance & Amazon for about $17 before tax.

The RoyalPurple, ToyotaTRD & Amsoil filters are all the EXACT SAME FILTER (other than cosmetic branding). And yes they are all made by Champion Laboratories. The comments and photos I saw indicated the quality of construction is quite high. Unlike all the others, they have metal end caps with silicone seals, metal cores and the filter material is mesh-backed. The RoyalPurple flavor is the least-expensive of the three. The least-expensive sourcing is Walmart-sold&shipped for about $16.75 plus a $7 shipping charge, before tax.

The various cellulose filters were generally available in the $6 to $13 range.

I saw enough negative comments along the way to sway me away from FRAM, Purolator, STP. YMMV. BeckArnley is now a brand owned by a company named DR1VParts and apparently has become mostly a reboxer of sourced parts. The NAPA Gold oil filter appears to be sourced from Wix. STP is licensed to AutoZone by Energizer Holdings for house-branding its oil & air filters.
