I just bought 2 older gti's, one of them works great so far and the other seems to be fine. The 2000 gti fuel gauge seems to have a issue. First it does not give a reading on the level of fuel, second the oil idiot light does not turn off. I've looked over other posts and will try to check the sending unit later today. My question is this, does the oil idiot light being on and the fuel gauge not giving a reading tell me anything at all ? I know the thing has Oil in the mixing tank I can see it. Second question, I want to take them out to give them a run tomorrow, with that light being on could it mean that oil is not mixing with the fuel ? The last think I want to have happen is to burn up the engine
