YES
TRIM it anyway,
its all bullshite,
all these addatives being discussed no reference to the harm it does to fellow onlookers regarding the fumes they omit also to other road users and lets face it , it only gives people an edge for a while no matter what they put in the tank they all want more and the end result is usually tears,
power from tank fuel is what its all about if not just NOX it and be done
