A friend of mine runs a small chain of gas stations here in Spain. Here, by law, everyone (all the gas companies) must buy their gas base from the national provider. This means that everyone starts out with exactly the same base, quality-wise.
I then inquired about the difference in quality of gas between brands and the purpose and value of additives, and he answered this:
Additives -any additive- costs less than the gas itself. So the more additives you add to your gasoline, the less actual gas you get in the end.
Do the math.
