Ummm doesnt higher octane fuel actually burn colder than lower octane?

From what I know we only use higher octane to prevent engine knocking given that it burns at a lower yet steadier rate.

 

I don't really understand what you're saying.

1. He's running his engine at >230 degrees. That's hot. Engines suffer when hot. Oil doesn't lube well when hot. He can't go over 60mph or put any load on the engine without it getting even hotter.

2. That's regardless of whatever octane he's running.

3. My point was that blocking the radiator to improve aero and improve gas mileage is robbing Peter to pay Paul.

4. If you wanted to save money on gas (without resorting to blocking off your radiator), you could run cheaper gas and drive like a granny... thereby not needing higher octane gas. Temps would be far lower than 230 because of effective cooling.

 

True.. you would save money with 87, but at the probable expense of engine knocking. Sure you can get away with it but who wants to feed their baby with fuel that knocks them upside the mouth

hope u guys understood my super lame pun! sry its the , and lots of it

 

I think his factory MPG is too low. We have all gotten better MPG.

 

Hm. by the way, running lower octane actually INCREASEs gas mielage (as long as the car doesnt pull timing due to knockage). Lower octane fuel has a higher energy content, IIRC.

By the way, is this guy who did this who I think it is? Someone was asking earlier how to get the car to run hotter to get better gas mileage...hmm

 

When I worked at Ford, My delivery truck would get better MPG if I used 91. If I used 87 it would knock like crazy.

 

Remember tho depending on location only premium gas
will contain no ethanol

 

Impressive mileage without a doubt, but its such a waste of a fine car..
get a prius & sell the S2k to someone who will use it for what its made for

 

Amazing how most of you have nothing to contribute to his thread. Pretty cool to see that our cars have that kind of potential, I've actually been getting 26-27mpg city only but I don't really get on it at all.

 

Not really that amazing. Discussion forums are there for sharing opinions as well as facts.
