Yeah,
Chevron had "mistakenly" sent a fleet client of mine 600 gallons of it instead of Delo 400 MG. Everything was fine until the UOA's came back the next month telling us that the additive levels were off, and this wasn't our typical Delo signature. From what I remember there was less Boron in the Ursa Super Plus and a little more Zinc and less Phosphorous. Overall the wear metals/1,000 miles didn't look all that different at 20k miles. The TBN seemed to drop off just a little quicker with the Ursa Super Plus in the end, but it still made 20k. All and all I would say the "experiment" was successful and I wouldn't hesitate to use it if it was cheaper than Rotella or Delo.
