My 09 E was due for it's first oil change, so I brought it in to the dealer last Friday.
At somewhere between 5300 and 5400 miles, the L1 code and the 15% oil life message came up on my dashboard. I was about to take it in anyway, so the timing was perfect.
Anyway, I was seriously thinking about putting synthetic oil in but since I would probably be changing oil at about the 7500-mile mark if I did so, I asked the service guy if the oil life computer could be adjusted to allow for the longer oil-change interval with synthetic, or would the L1 code and 15% oil life message continue to come on at 5400 miles or so (As you know, when that code comes up, you can no longer see your mileage or the outside temp reading.). He said there is no way for the computer to know if there was regular oil or synthetic oil in the vehicle so, yes, the codes would continue to come up at the lower mileage.
Was he right ? Any way to "adjust" the computer for this ?
Thanks.
