Hey everyone, i was chatting with a rover specialist out in Long Island, New York and he explained that oil change intervals should be every 3k miles or three months on our LR4's. He said that even 5k/6 months intervals were too long for this vehicle. Apparently our engines are very prone to engine sludge since the oil filters made for our trucks don't filter oil as well as they should. I'd like to hear how often everyone changes their oils and what mileage they currently have on their truck. I don't know if i agree with a 3k/3month interval as i think that's a bit excessive, but maybe i am wrong and the rover specialist is correct. Please shed some light on this for me guys!
