Erubin,

I'd run it as is until almost out of fuel and see if filling with the fuel you previous used made any difference. Let us know if different fuel does makes any difference. You might take off the fuel line and drain a little fuel to see if it has water in it. You can do this without spilling much if you jack up the car or put it on a lift or back the rear end over a drop off. The water will be in the bottom of the tank and come out first.

I have never seen any type of Diesel fuel I used make any difference in running in any of my Diesels. I have used, kersosene, 2 cycle gas/oil mix, fuel oil, vegetable oil mix, used crankcase oil mix etc. Diesels are a multi fuel engines and run on almost any type of liquid fuel.

I've been running Diesels for 35 years so I have a lot of experience.
