Pumps, dispensers and devices for blending gasoline and motor oil.
1.
The use of pumps, dispensers or other devices which are capable of withdrawing gasoline from one tank containing gasoline and another tank containing motor oil and dispensing them as a single combined product and of withdrawing gasoline alone from the tank containing gasoline must be authorized if the Division of Consumer Equitability of the State Department of Agriculture determines that all the following conditions exist:(a)
The device mechanism accurately measures the quantities being simultaneously withdrawn for dispensing as a combined product from each of the two tanks when the combined product is dispensed, and the quantity being dispensed from the gasoline tank alone when gasoline alone is dispensed.(b)
The device mechanism accurately and visibly records and displays the ratio of gasoline to motor oil, the quantity of each ingredient being dispensed, the price per gallon for gasoline being dispensed and the price per quart for motor oil being dispensed, or accurately and visibly records and displays the ratio of gasoline to motor oil and the total volume of the oil and gasoline mixture delivered, and computes the total cost based upon the price set for the finished blend.(c)
The device mechanism prevents the changing of the ratio of gasoline to motor oil during dispensing.(d)
There is firmly attached to or painted upon the device mechanism panel a sign or label plainly visible consisting of the words “two-cycle motor fuel” together with the brand name or trademark of the product, all of which must be in letters not less than one-half inch in height.2.
The provisions of this section authorize the operation of a blending type of pump or dispenser connected to two tanks, one containing motor oil and the other gasoline, but only if the motor oil in its separate state meets the specifications for lubricating oil as required by NRS 590.080 and the gasoline in its separate state meets the specifications for gasoline as required by NRS 590.070.
