2. the value of specific gravity of the oil.Analysis of the oil lamp, for example, to measure the volume of a certain amount. The density measuring tube in oil, for example, by measuring the density measurement tube density range only. So if a sunken tube or excessive Loy The density measuring range should be changed to suit the type of fuel. After that, apply the values that are entered into the program to calculate the value of specific gravity and a value to compare with the quality of oil.
