Are all gas stations the same(Exxon, Shell, Chevron, Wal-Mart)?
well i have also heard about the diffrent additives also – but about the tanker there is a plus and minus to that – maybe it stirs up the setiment but it also has a higher octane rating – i know a few race gas dealers that have told me 93 octane for example is made at about 95-96 octane and by the time it reaches the fuel station it has lost 2-3 octane points – the fuel has a higher octane the fresher it is.
