I have a 2006 Mazda 3, with the 2.3L engine, where you replace just the oil filter cartridge itself (i.e. it's not a spin on type).
I noticed on Rockauto that some of the fancier oil filters claim to have an anti-drainback valve to help prevent dry starts, which seems like a good idea. Although confusingly, some say in the description that they have the valve, but in the list of specs that they do not, e.g.: https://www.rockauto.com/en/moreinfo.php?pk=924852&cc=1432714&pt=5340&jsn=465.
On the other hand, the popular and highly lauded Fram Ultra, at least on Rockauto's site, says that it does not have an anti-drainback valve.
So, should I really worry about this? Or just get what seems like a good quality filter?
(Also as a side question, does anyone know if the Motorcraft filter is identical to OEM on the Mazda? I know the Mazda shares a lot of parts with Ford.)
