Answer:
Mass of oil will be 7.176 pound
Explanation:
We have given specific gravity of oil = 0.86
We know that specific gravity is given by 

Density of oil = 
We have given volume of oil = 1 gallon
We know that 1 gallon = 0.003785 
So mass of oil = volume ×density
mass = 0.003785×860 = 3.2551 kg
We know that 1 kg = 2.2046 pound
So 3.2551 kg = 3.2551×2.2046 = 7.176 pound
