Broke 0 #26 May 1, 2008 Quote I would love to hear from one of the resident experts. One question: How do we know they're really resident experts? Actually I have heard that running a higher octaine can do more harm than good to an engine. The only reasion you should be running higher octaine gas is if you have a higher compression engine. Or if you are running a turboDivot your source for all things Hillbilly. Anvil Brother 84 SCR 14192 Quote Share this post Link to post Share on other sites
Beerlight 0 #27 May 1, 2008 QuoteQuoteQuoteI have 2 vehicles but the one in question is an '07 Civic Si. I personally don't mind the extra 10 cents/gallon in order to get the best performance from my engine. Maybe we can have one of our resident experts speak, er write on octane v. performance...pros/cons..etc.... The Si engine is a high-revving, short stroke, high-compression engine. It needs the extra octane. The knock sensors can only do so much against a low-torque power plant. I drive a 4-cylinder inline, 4-stroke, DOHC, w/ a 11.5 to 1 compression ratio that makes 147.8 BHP @ 10,000 rpm. Redline is 12,000 rpm. My manual states 87 octane is recommended. Been running that for years now, no problemos. OK, it's a motorcycle but seems to me about the same as a small car. Quote Share this post Link to post Share on other sites

RALFFERS 0 #31 May 1, 2008 Quote damn i love my hybrid you really cant beat upwards of 40-50 miles a gallon Tue - but many people in the automotive industry told me those batteries/motors need maintenance or replacement every 3-5 years. If that's the case, I'd rather have a car that gets 35-38 MPG & spare myself the extra costs. Damn shame too! - Chevy just came out with a hybrid Tahoe; I love that car...

RALFFERS 0 #33 May 1, 2008 QuoteHere it's $3.59 and going up.So, now the question is - will gas ever go back down?? I can't imagine that it'll continue just going up (of course, what in the hell do I know...)

mamajumps 0 #35 May 1, 2008 Filled up for $3.56 a gallon at Wal-Mart in Florida. If you use a gift card to pay for your gas, you save .03 cents per gallon. Ive been doing it for years... .03 cents adds up! Quote Share this post Link to post Share on other sites

BillyVance 34 #38 May 1, 2008 Quote Quote Toyota MR-2 Spyder convertible. Did that come factory with a rainbow sticker? Hey, I wasn't the one who bought it. My wife did. She wanted a fun car to drive to reward herself for earning her Masters degree. I admit it was a fun car to drive, but I liked my old 1975 Porsche 914 better. And oh yeah, I have gotten speeding tickets in both. Hell I have speeding tickets in just about every car I owned, including both of my wife's cars! When she got pregnant, we traded the Spyder in for a family car."Mediocre people don't like high achievers, and high achievers don't like mediocre people." - SIX TIME National Champion coach Nick Saban Quote Share this post Link to post Share on other sites

sharimcm 0 #41 May 1, 2008 It's the same in Texas... $3.44 is the cheapest I found it and that was at Wal-Mart (Murphy USA). The usually going price is $3.49/gal.
