I've been scouting the internet to find an answer and it seem to boil to the same issue, using the wrong oil brand... My 06 DE just had its service, I've been checking the oil level religiously, I've found i use about 1L per 100 miles, I've done about 300 miles and the oil seems mega dark, should I try a different oil or just head out for an engine rebuild?
