was filling up the 16.3 gallon tank on my current car with 93 octane this evening... 300 miles for 16 gallons = less than 20 mpg... plus Super is always at least 20 cents more...
got me thinking... what is Toyota's "recommended" fuel for the Prius?? I saw that the new engine will be 13:1 static compression ratio and depending on valve timing this is extremely high.
My 325 calls for 91 plus and is only 10.5:1...
A friends S2000 calls for 91 and is 11:1...
(for everyone's info, there is absolutely no more energy per volume of gas for a higher octane, this "rating" is a ratio or percentage of 8 carbon gas to non-8 carbon gases (heptane and lower) - more power CAN BE EXTRACTED from a higher octane because it is MORE STABLE)
