Re: Gas Companies and MPG
These assertions are, by and large, entirely false. Gas is gas. The difference between most brand names and no-brands is that brand names add differing degrees of their proprietary detergents into the fuel and advertise the difference as being better for your engine's longevity, performance, etc. Government regulations demand that all gasoline has some minimum level of detergents in it so it's not like you're missing out with no names. Additionally, those no-name stations don't actually drill for and refine oil like Shell, BP, Chevron, etc... Where do you figure they're getting their gasoline from?
Most new engines can handle gasohol without issue, but whether they need it or not is another question. Ethanol gives the gas a higher octane rating and therefore reduces knock. Great idea for your grandpa's carbeurated clunker, assuming it can handle the gasohol at all, but not so much your 3. The supposed benefit is that it burns more slowly and completely, thus producing less emissions. It's not cheap (money or energy wise) to make, though, so the benefits of burning it are probably largely mitigated by making it, but I don't know about that.
