I got a 2003 Jetta TDI that’s been sitting parked for about 2 years. Before my wife parked it I asked if she ran it dry and the response was yes. We need it again so I got it running new oil, filter, fuel filter, air filter and a few other things. But it has about 3/4 tank of diesel that was left in it. I opened up the fuel tank and inspected the fuel and it looks fine with no water, rust or growth.
It needs an emission test so will this old fuel cause a fail? Is there something we can add to it? Or should I just drain it out? The issue with draining is 3/4 tank is about 10 gallons and I got nothing to store it in.
