Lesson learned here is on MY application: makes NO difference which one you use for 5-10k mile intervals (all filters here have a minimum of 5k and max of 10k miles). These are all Motorcraft FL1A cross references used on a zillion Ford cars and trucks. Every last one looks like it could have gone much longer. The long interval ones (Boss, M1, Wix XP) were run 2 intervals. Prices I paid are as follows in the order of pics from left to right: STP extended life 8.99 AutoZone, Purolator Boss 9.49 Amazon, Wix 7.44 Amazon. Wix XP 6.77 Amazon, K&N Pro Series 7.12 Amazon, Bosch Premium 5.46 Amazon, Mobil 1 9.98 Walmart. I drive my vehicle all day for work which equates to oil changes about every 2 months or 5k miles . All of these are under 2 years old. Truck has 282k miles and runs like a top (things like fuel pump, water pump, coil pack and maintenance items etc have obviously been replaced as needed/scheduled along the way).
