Why does the manual state to not use any fuel additives? Many fueling stations already incorporate additives in their pumps?

Compatibility mostly, not all additives play well with each other.
The only fuel additive PCNA ever sanctioned using is Techron, which is a system cleaner, not a performance additive.
If you are buy quality fuel, it already has additives in it.
