I was looking at the filter difference between a WIX 3148 and 3148XP. The 3148 is paper the 3148XP is synthetic. The local auto parts store that carries WIX does not carry the XP model nor in his warehouses, they do have a 3148 in stock. Any experiences with either or should I travel the extra 15 mile to the NH Dealer for an OEM?
