This is perfect! I must admit that I only change at the ~ 20% oil life indicator, it happens only after I drive about 2500-3000 miles.
In my case, the time factor of the % makes the difference, since I do not daily drive my 1LE and I believe that the % indicator counts 365 days from 100%-Down to- 0%.
So even if I would theoretically not use the engine at all, if 1 year goes by since the last oil change, I will be down to 0 % no matter what.
