What's the price of gasoline around your neck of the woods? Here in Seoul, north of the Han river, for the regular stuff, it's about 1850 KRW/Liter, which translates to 1.80 USD/Liter or $6.85/US Gallon. My car requires premium, which is about 2350 KRW/L so it works out to about $2.30/L or $8.74/Gallon. That's right, $2/gallon difference between premium and regular! It's 10-50 cents/gallon in the cheaper parts of Seoul and once you get south of the city. On post (US military bases), it's closer to US prices at about $3.50/Gallon for regular. Edit: Added the question.
