Notes:
- I'd estimate the duty cycle split (in terms of mileage) 1/3 highway, 2/3 city.
- The bulk of the "city" driving was from trips approx. 25-30 minutes in duration.
- First sample taken at 3425 miles / 151 hours
- Second sample taken at 4676 miles / 205 hours
- Oil was NOT changed at first sample. Second sample was taken upon changing oil (but not filter), including the addition of the "polar vortex" with a couple cold starts below -20°F
- Yes, the second sample did arrive before the first sample. USPS had it for close to 8 weeks. (That's what happens when you mail it in one of the Blackstone Laboratories kits without putting it inside another box/bag/mailer)
