I just made it to 1019.7 kms on a single tank of fuel! When I filled it, I was at a diesel pump that had the larger nozzle for big trucks and I couldn't completely fill the tank up to the very very top because the fuel kept foaming and spitting out of the filler neck. I managed to put 54.7 liters into it. I also tossed a half bottle of Redline DFC in there too.
Nice, that's about 40 further then I ever got in my 92 TD jetta
93 Jetta w/ AAZ. To be fair, I was damn near completely empty when I hit that distance. It stalled when I pulled into my driveway and it took about 20 seconds of cranking to get it to start back up again. My brother has a vacuum pump so it wouldn't have been too much trouble if it was totally dry but I didn't need it thankfully.
