Dang! 2000 OCI on Havoline, Bubba? I see that years comtemplation here have not been of any help...
Perhaps you need to climb the mountain..Speak to the Man!
Sprint-ski..
Oil change shops, dealers and garages of every stripe drive the madness. Oil filter companies, the oil companies, too. Its a giant industry, and besides, we're only one generation (people-wise) since the engines went EFI, the metals got good and the oils became superior.
The transition will be fought by the industry, but people will come around sometime. Besides, EVERYONE isn't doing 2,3K OCI, tinkering with the adds and all the rest. That's a small percentage. Most of em here, or hereabouts.
I wonder if it'd be possible to calculate, extrapolate, and collate (?) some way, maybe through filters or quarts of oil sold or something to figure out what our "National OCI" is..
Easy for you to say, anyway, Sprint, YOU have GC after all..
