Nope. Either no increase, or a DECREASE.

ALL gasolines on the US market today are subject to US federal EPA
regulations (and, in addition, sometimes even state EPA regs) governing
detergent additives. ALL gasolines on the US market today have detergent
content sufficient to maintain emissions system performance as mandated by
the EPA. This primarily means deposit control.
