hey diesal,
rocket fuel costs approx R60 a bottle, if i remember correctly the bottle is approx 100ml, my oppinion is to mix both rocket fuel and prolong, its actually cheaper to buy prolong and use it on its own as the bottle is much bigger, also prolong has water displacing properties in its composition hence it works much better!!!!!
