After drove 351 miles on I-75 with 3000 rpm most of the time on the weekend, I found my oil was 1/4 qt low from the H line and some dark deposits in the tail pipes, which wasn't there before. Concerning the oil burning, I did a bit of search and found this TSB. I'd like to share it with you, particularly for the folks having the issue. I will be keeping a close eye on the oil level.
