One finnish tabloid newspaper, iltalehti has an article (in finnish) about their quick, not very accurate test drive. They drove a stretch of about 350km twice, once using E10 and the return trip using 98E5. Most of the trip was on quiet roads, following speed limits. They found out that using the more expensive 98E5 was cheaper in the end than the E10 fuel. The Ford Mondeo with 1,6l engine used 6,25 liters/100km of 98E5 and 6,68 liters/100km. The cost of using E10 was about 3,5% higher than 98E5.
