The following data is information gathered about Royal Purple oil filters from various applications. Any listing with a date code is data taken from an actual in-hand oil filter unless otherwise noted. If there is no date code listed, it is general information taken from somewhere online and information like the country of origin should be viewed with skepticism. The "Check" date is when the oil filter was last checked. If a date code says "None", that means it was in hand but no date code was found, even when checked with UV light. If you see a part number multiple times, it is because multiple examples have been checked, so changes may be noted. The "Plain" number removes the brand-specific letters and numbers to show the similar/common code among some filters for the same application.
Be aware that this is compiled by hand and subject to mistakes, so don't buy a filter based only on application and quality data found here.
