Blaze

Vicky's Nissan has been acting up lately with regular octane 93 unleaded gasoline, and we've been loading the vehicle with octane 95 or 96 gasoline in order to minimize the engine knock.  I've been pretty frustrated because the instruction manual clearly states that the vehicle can load octane 92 and up, and the "trill" sound generated by the engine just drives me bananas.  Just last week, Vicky loaded the vehicle with Petron's 100 octane Blaze and voila...the engine knock has practically disappeared!  I understand that Blaze 100 has been loaded with premium additives that are supposed to clean the engine and preserve the catalyst, which is also why the price of this premium blend is much higher than regular gasoline.   In addition, ordinary gasoline from octane ratings 88 to 96 have been blended with 10% ethanol, while Blaze 100 has no ethanol, which is probably another reason why the product works better on engines with higher compression levels.
