My SDL sat just over one year before I purchased it here and consequently the fuel in there is of the same age also. There's around 1/3 tank remaining in there and I'm not sure if I should mix it with new or try to drive around with that old stuff.

What do ya guys have to say?

I say add good fuel to that and use it ...
When I sold my 81 wagon it sat for 18 months... they guy that bought it simply put a good battery in and it started within 2 seconds.... he was not surprised... but I was...
Now regular gasoline would be different...

i found a full fuel oil storage tank in the basement of my building that held 2500 gallons. i estimate that it sat for 40 years. i used a tank in my 350 sdl with no ill effects and then sold it all to a freind who has heavy equipment. he burned it all in a week or two and had no problem.

this is the short version of this story.

Looks like I'll add some fresh to it and run it!

I have a similar story. When I bought my place there were two 55 gallon drums of diesel in the barn. The guy who I got the place from had been ill for a long time, so the fuel had been there a few years when I moved here.

After a couple more years went by I decided, what the heck. I pumped some in my tractor. It looked good, smelled okay and after running a few tanks through the tractor, I burned most of the rest of it in my 240D.

I also would just run with it and keep an eye on the prefilter.

Good luck,
