Jane you were promised a lot of opinion and I'll help deliver on that promise.
I took the time to examine the load report my fuel truck delivery guy gets from the tank farm when he loads. The USDL is delivered into his truck as stated to have lubricity additives and a cetane additive to a minimum of 40. The cetane of 40 is the general minimum required by engine makers. The lubricity additive is subject to discussion.
I buy Power Service Diesel Kleen as well. I get it at target or Walmart and its about 10 bucks for a 96 oz jug, which treats 300 gals to boost cetane by about 6 points. This product also adds lubricity to the ULSD. I don't try to be precise. When I know I need more than 100 Gal in each tank I drop half a jug into each tank and ad fuel. I'm boosting somewhere between 4 and 6 points in most cases and that has given me a fine improvement in a low smoke start up, but as for lubricity, talk to me in another 6,000 gallons of fuel.
I operate in Ft Lauderdale which is a warm and virulent environment for microbial growth. I do not treat my tanks for flora/fauna growth routinely, but I monitor my Racors closely and treat on signs of distress.
Hope this helps.
Oh I did the math a while back and PS Diesel Kleen ads about 0.06 cents per gal. boosting a full 6 numbers. And boosting over a cetane of 50 can actually increase smoking at all RPM's.
