NAPRO® B-4000 is specially formulated to help heating oils obtain top burner performance. More useable heating value (BTU's) per gallon/liter of fuel means less fuel is required to maintain the same temperature or steam pressure. This results in fuel savings in oil fired furnaces. This all-season, energy saving fuel oil combustion improver is an organic petroleum derivative and burns completely.

All types of burner fuels, home or industrial

One (1) U.S. gallon of NAPRO® B-4000 to 4,000 U.S. gallons of burner fuel assures maximum results. In small fuel tanks, add one (1) U.S. ounce to 32 U.S. gallons of fuel. One 55 U.S. gallon drum treats 220,000 U.S. gallons of burnerfuel.

NAPRO® products are shipped in steel, non-returnable 55 U.S. gallon drums ready for repackaging and industrial uses.
