My neighbor just today shared with me a fact about Mountain Dew and other citrus flavored products. Mountain Dew products contain bromated vegetable oil. Bromated vegetable oil is used to disperse citrus flavored soft drinks. Which means it's added to keep the citrus flavor additive from separating with the other ingredients creating density (cloudiness). It's true the next time you are in any store check out the ingredients it will be listed probably near the end of the list. It's not harmful because FDA regulates how much is to be used but could present problems if consumed in large quantities over a period of time. Personally this makes me not want to drink Mountain Dew or any other citrus flavored drink.
