Do you mean oil filters that hold more oil than normal to avoid dry startups?
It is kind of tough to explain. In fact, I didn't notice the startup shake for many years of ownership.
I can say that with some filters, like AC Delco, I used to get engine shake/quiver on startup. Always in the morning after the car sat overnight. I'm assuming that some anti-drain valves don't work as well as others. Otherwise daily startups were all good, without any shake.
A while back I wanted more filtration, so I switched from AC Delco to Purolator Pure One. I didn't get any better filtration, from what I could tell. But the startup engine shake, which I always thought was normal (dry friction), was gone. Weird, I know.
Anyway, today I'm looking for better filtration, but I want to keep the "no shake" startup. I don't want to go too far beyond $7 per filter, so Mobil 1 or K&N are not good for me.
The only other in Purolator Pure One's range is Wix.
Most 5.0 owners may not even be aware of the shake/no shake startups to comment on Wix oil filter.
Sorry, if I'm making a big deal out of maintenance, but I currently don't plan to do any modifications.
