An oil filter doesn't care if the oil is mineral or full synthetic oil. The reason you see some filter makes say the filter is "for synthetic oil" is because those oil filters are rated for longer oil changes, and the filter maker doesn't want someone using a filter rated for 5K miles with out rated for 15K miles and over-use the filter.Proselect as far as I know are made for low oil change intervals and less efficiency also only for mineral Oils.
Yes that was my point. Cheaper filters=Lower oil change intervals. Media is not able to whitstand 15K miles. These filter media often has less grammage and lower Mullen values.An oil filter doesn't care if the oil is mineral or full synthetic oil.

A lot of people do 5K-7.5K mile OCIs even with synthetic oil. About every oil filter these days can take that amount of miles unless the engine is a total sludge monster.Yes that was my point.
