I ran this oil pretty aggressively with Italian tune-ups and many sprints at subzero temperatures entering 70 MPH highway on ramp literally less than 3 miles away from a quick warmup from a 45F heated garage. The other two oils which were Idemitsu IFG7 0W-16 with the high Moly and Pennzoil Platinum 0w-16. The replacement oil was again Ravenol 0W-16 EFE and will try to keep OCI under 7,500 miles afterwhich I may jump to a 0W-20 or 0W-30 for summer use oil. BTW BS turnover was lightning quick, 6 days. The journey continues.
