Re: Much smoother than RT6 To overcome extended drain anxiety, consider doing used oil analysis 1000 miles before scheduled oil change.
You can confidently, continue with the oil if the report indicates all the levels to be within spec. Repeat the oil analysis again until the report recommends changing the oil.
This is the most informed and scientific way to establish oil drain intervals. We see conventional oils breaking down below spec before their scheduled interval, indicating accelerated engine wear (even with frequent and regular oil changes). Therefore, the condition of the oil should be the factor that call for an oil change. Replied by Tech Admin
