Spot on. My 2F's got 15,000 miles. Running 5W30 AmsOil or Mobil1 and a CAT filter. Would highly recommend.Rebuilt 2f with new seals and has been running on synthetic? Mobil1 high mileage from costco.
Oil pressure at start-up is immediate compared to running 15W40, is nearly identical at hot idle, and 0 leaks or other deficits to report.
Blackstone Labs analysis also reports it's more than healthy.
