I just ran 15,912 miles on HPL No VII Euro 5w30, for about $80 since I was able to pick it up in Manteno. That’s $5 per thousand miles.
If you’re using the average shelf oil from WM @ say $26.97, and use one filter for 5+ 3k OCIs to match my mileage, you come up with $143 just in oil, which comes out to $9 per thousand miles. If you change filters at every OCI, add in another $40-75. Plus the time, effort, and 24 extra quarts of waste oil to dispose of.
How exactly does this method come out to be cheaper?
