Q Can I use Stanadyne Diesel Fuel Addtives to treat Bio-Diesel?

Q Can Stanadyne's diesel fuel additives be used in bulk storage tanks?
A All Stanadyne diesel fuel additives are suitable for use in bulk storage application. However, the conditions under which it is added to the storage tank will have an impact on the rate at which it is dispersed. The level of homogeneity of additive in the tank depends on several factors such as temperature of the base fuel & additive, the size of the bulk storage tank, the degree of agitation in the tank, etc. If there is mixing/agitation in the storage tank, then the additive will be homogeneous and remain that way. However, if there is no mixing/agitation the level of dispersion in the storage tank will be an unknown variable as the rate of dispersion depends on the factors listed above. To obtain proper dispersion in a bulk storage tank, add the recommended ratio of fuel additive to the tank prior to adding the fuel. The addition of the base fuel will provide the necessary mixing/agitation. At the end of fueling, the mixture in the fuel tank should be homogeneous.
