Even though probably true, the mileage ratings I take with a grain of salt. Sort of like "lifetime" fluids, hours ratings on the LED bulbs in my house etc.The one thing that would make me decide not to continue using this oil is the fact that Valvoline really hasn’t given this oil a mileage rating so that makes me wonder if it’s something that I would want to be running for 10,000 mile intervals in my Civic (when I follow the oil life monitor it typically signals a change at 10k)
I still haven’t fully decided but for me one of the front runners I’m considering is M1 EP HM, for the fact that it claims to clean up sludge in one interval and VRP doesn’t claim to do anything about sludge (not that my engine has that issue but just that it might be a good idea to give this different chemistry a shot too, and we know M1 EP can easily handle 10k OCIs)
Many things are different for everyone, the vehicles, the motors, the long/short/driving/idling conditions. That's why some of us crazy OCD people at BITOG do UOA's and people think we should be committed. Just bring it to the dealer at OLM and never worry. If bad replace with the next lease.
How is the 10k mile warranty covered and what proof is needed that it didn't hold up and caused motor failure that they can't blame on something else. If I ever get to doing higher mileage trips where I might consider that I'll see. Currently I'm 2-3 changes per year on each car doing about 5k intervals now.
