Ok I'm sure I've seen this topic here before but I can't find it. I thought I read that most people were getting around 10000-12000kms per oil change. I had the oild changed when I bought the truck and I had around 10000kms before the oil change message came on. I put synthetic in this time and now I'm barely at 4400kms and the message is coming on?? All of the kms have been on the hiway and the only thing I have hauled in the box is my quad. Does anyone else go by the sensor or by kms?
