I just got a new civic DX-VP 2 weeks ago. While I was there I was talking to the salesman about oil changes. I've always changed oil every 3K miles but he said it was bad for these engines because it can ruin some engine seals. Has anyone else heard this? He said every 6 - 9K miles. I have also changed the oil quickly (<1K miles) when the engine is new for just the first time. He also said this was a bad idea and suggested to just use the 6 - 9K rule and watch the oil life gauge. Using this info as a guide is fine with me but I don;t see how changing it earlier could hurt as he claimed. Has anyone else been told this?
