This is a sweet little car to drive and very economical at the current price of gasoline. I have a used home pump which fills the tank overnight. My price per gallon equivalent at home is about $1.53 per gallon equivalent. Because the fuel is so clean, oil changes at 10,000 mile intervals could probably be delayed further. I have had essentially no major problems with the car. It has saved me a really large amount of money--especially now that gasoline is going for $4.72.
