This is a heads up to those who, like me, have had performance issues since last October. Symptoms included running hot, poor acceleration, loss of a deep sound from the pipes, dramatic decrease in gas mileage, and a coffee grinder sound coming from motor when accelerating sharply. After hurricane Katrina the government evidently relaxed standards for gasoline and many of the additives are no longer added. Performance issues are particularly evident on our larger motors. Johnson Performance in Sarasota suggested putting octane booster in at each fill-up (bottle is for 15 gallons so you have to make sure you only pour in 1/3 a bottle at fill-up and keep it away from your paint!). What a difference! Great having the SEEG performing like it use to! Others having these issues? If so, octane booster may just be the ticket.
