Running old furnace/diesel fuel

[burn_your_money]

I usually run glowplugs at least 3 years, if not more before I have to change them. How long do they last for you mystery?

Ah yes, I forgot about the ULSD. I actually had the benefit of being able to run LSD this past few tanks.

ive noticed no difference between the old diesel and treated new diesel.. i never ran a tank of straight ULSD to compare it to the old high sulfur diesel..

How much parafin are you running and how are you mixing it?

I ran a half brick last summer with a tankful, seemed to help.  Gulf wax from the canning section of the grocery store.  I just put it in with a gallon and leave it sit in the sun and it disolves in a couple of days, then dump it in the tank.  I used my empty glass gallon jug of apple juice so I could see the action.

I run dura-therms and the seem to last in the 12-18 month range, and I live in California. Although where I live we get some freezing temps, I think last year my low morning temp was 28*F, about -3 or 4*C if I'm not mistaken. I need to pimp them.

Seemed to help with what? Mileage? Power? Both are easily quantified.

Wax did seem to help with power, however I don't get enough miles to check my mileage accurately.  My jetta generally gets filled up every other month.  I have the low rpm surge/lope that the wax reduced, but when it turned cold (40F) I haven't added wax.  Check the thread in the other area (troubleshooting?) a lot of guys are into this.
