Well here we go again ,it's either oil filters or oil,,
This question regenerates itself over and over!
Ok , lets roll with it ,
How much oil does a oil filter actually filter?
Answer not much at all! considering the amount of flow passing thru it.
In HP motors, will a HP filter filter more or less oil?
Answer, yes and no, why is that? because a HP filter allows for more oil to go thru it with out actually filtering the oil at all.
The more filtering medium used the actual less filter gets done!
So depending on the application , don't run a cheap standard filter on blown alcohol motor, or in 'disel' application don't run you cars filter on it.
Change you're oil at regular intervals use the proper weight of oil for the application
Now everyone can argue over it say what ever they wish , those are the facts!
By the way, I don't care what filter you run , just so long as it is used in the application that reguired for it!
