Diesel additives?

[Gale Hawkins]

While the first 8 came out OK it boggles my mind some at the bottom had a negative results.

Best I can say is that I base my decision on real world experience both first hand and from others.

I went to my own 575 gallon tank several years ago. I buy 500 gallons BP/Amoco Premier #2 50 cetane fuel and treat the fuel in batches. The tank vent is filtered with a dessicant breather, and I have 2 filters plumbed in series and as a primary/secondary based on micron rating. I seldom, if ever buy diesel at the pump.
