morning,
it seems there is a wide variety of critisism regarding this. i'll go through another tank and see if there are any gains. chances are that i will to back to #87 just because a 10% gain in efficiency cancels out the cost of premium which is 10 to 15% higher than #87 in my neighbourhood. i have found that different brands of premium give me different results. Shell V-Power gives me the greatest gain while Crappy Tire #91 must be full of ethanol, not giving me the required boost for my test. too bad i don't have a dyno and a fuel monitor. that would give me the best test.
