I have an 03 Ford 7.3 Power Stroke and I'm currently using Motorcraft FL-1995 oil filters. I have been reading about the Fleetguard LF3974 Stratapore oil filters and was wondering if the Fleetguard gives better protection and worth the extra money. I'm changing oil and filter every 5K miles. Not looking to extend oil change intervals, just the best protection for the engine.
