I remember reading a msg from the PS people.. and you can actually use a 'stupid' amount of concentration without harm.. but you get no bettter results than about the double dose level.. etc... at least for the white bottle anyway..

If you read the label, 32 oz. treats 100 gallons of fuel; ergo 32 oz. divided by 100 gallons = .32 oz., times 5 gallons = 1.6 oz., doubled equals 3.2 oz. per 5 gallons for the recommended maximum doseage 
I reused an empty 32 oz. Sta-Bil bottle; the one with the little measuring vial attached, and filled with the PS. Squeeze the bottle to fill the vial to the one oz. level three times, dumping each time of course, then to the quarter oz. level and voila!, you have your measured max. dose I'm of a frugal nature and won't waste anything

Read the new PS labels before you add it, because the instructions have changed. They no longer tell you to double dose for winter, and the bio dose rates are down quite a bit. It makes me think too much is a bad thing for the engine, or that too much doesn't work as well as the proper dose. I posted about this a month or two ago but here are the dose comparisons again right off the white bottles:
Old bottle rates:
Summer = 32 oz per 100 gallons of fuel (.32 oz per gallon)
Winter = 32 oz per 50 gallons of fuel (.64 oz per gallon)
BioDiesel = 32 oz per 30 gallons of fuel (1 oz per gallon)
New bottle rates:
Winter and Summer = 1 oz per 3 gallons of fuel (.33 oz per gallon)
BioDiesel = 2 oz per 30 gallons of fuel (.64 oz per gallon)
Old bottle rates:
Summer = 32 oz per 100 gallons of fuel (.32 oz per gallon)
Winter = 32 oz per 50 gallons of fuel (.64 oz per gallon)
BioDiesel = 32 oz per 30 gallons of fuel (1 oz per gallon)
New bottle rates:
Winter and Summer = 1 oz per 3 gallons of fuel (.33 oz per gallon)
BioDiesel = 2 oz per 30 gallons of fuel (.64 oz per gallon)

Perhaps they have changed their formulation, as the last bottle I purchased still had the X2 winter doseage recommendation Certainly want to adhere to manufacturer's recommendation's on (any) additive

What do you use to measure .58 ounces?

I got away from the messy measuring cups and funnels and the need to clean them all up after every use when I set up my fuel drum and pump.If you read the label, 32 oz. treats 100 gallons of fuel; ergo 32 oz. divided by 100 gallons = .32 oz., times 5 gallons = 1.6 oz., doubled equals 3.2 oz. per 5 gallons for the recommended maximum doseage
Now I simply dump a quart of PS in the drum before filling it.
I've done the same. It's quick and easy. Two squirts to the 1oz mark and then I'm off to fill the diesel can. I've had no gelling issues using road diesel (pre treated I'm sure) and adding PS.
