My experience with the Clarity needing an oil change hasn't been called for more often than I estimated. The first call for an oil change (A01 service I think it is called) was at about 4,000 miles which I thought was reasonable. Yes the engine hadn't run much but I think changing the oil on a new engine soon after it's new is reasonable. Now the car has 27K miles and is 16 months old. So in for another oil change. I have been reluctant to use Jiffy Lube just so I don't void any warranty conditions. BUT, after waiting a week to show up for my appointment, it took the Honda dealer 2 1/2 hours to simply change the oil. Jiffy Lube from now on. I asked the service technician if there would be any warranty issues if I used Jiffy Lube and he said it would be fine. I'll just make sure to keep records.
