Congratulations on your purchase and welcome!
First things first - there is no Amoco. Several years ago they sold their motor oil line to Chevron, who kept the name but used their own formulations with the exception of a couple items like hydraulic oils, where they used Amoco's formula. Then a couple of years later, they sold their light oils (fuel, gas) division to BP. BP kept the Amoco name as they had a reputation for quality products, in particular in the midwest. When BP aquired the refinery in Mandan ND, they lowered the quality of gas 5 times before they ultimately sold that off as well (I know the head engineer at the refinery). And BP does not stand for Beyond Petroleum as their commercials would have you believe, it stands for British Petroleum.
Alrighty now that that is done. White gas was a common item 50 years ago. It's not anymore. White gas now refers to gas used in lanterns such as colemans.
The "White gas" you are purchasing at "Amoco" is premium gas - you can use it. Amoco used that marketing ploy before they sold out, saying that the premium, or gold, or white gas as you call it, were as pure as water.
