It is not an issue with all non oem filters.
These things are made to spec by a number of contract manufacturers. Easy for a bad run or something.
It is odd that Bosch branded units seem to have changed permanently. Very odd that (and I'm guessing) that none of the cars they support are also affected by this seemingly major change. I'd think that spec built oil filters would follow some rather stringent accuracy requirements.
Either way, at this point (and I could be wrong), I have only heard of Bosch changing to convex.
I have not seen anyone on any forum ever mention any of the other common brands making this change.
Has anyone else?
Either way, I'd switch to any of the other good brands before going Frankenstein on anything. IMHO.
MOBIL M1-110 is about $8 on amazon and works for me.
