Let's do the math --
- I don't know what the cost of a rebuilt engine would be but I'll guess around $7,000.
- Total cost of Racor oil filters for the lifetime of the engine - $558
- Total cost of Prime Guard filters for the lifetime of the engine - $230
- Total savings by risking Prime Guard over Racor - $328
#1 (engine value) >>>>>>>> #4 (savings) therefore I'll stick with Racor.
Calculations based on current pricing for Racor ($13.95) & Prime Guard ($5.75) filters via DieselFiltersOnline and assumptions 200K total miles & oil change interval 5K miles.
