What do you mean #2 only??

[kevin21]

Is there an additive that makes that big of a difference in performance? I always see you guys say, on #2 only. That does have to do with diesel fuel right?

Man I'm a rookie. (this is my first diesel)

They mean that there not using propane or NOS, just diesel fuel.

that means no propane or nitrous was used just #2 diesel

I run Ammoco 50 cetane premiere diesel or BP supreme diesel (same stuff) for pulling and dragracing.
