Last month OMV (one of two big oil companies in Slovenia) started to sell OMV Sprint Diesel – a “new” kind of diesel with additives. They decided to give out 5x 100 l of diesel to bloggers with diesel cars in exchange for opinion. I applied and I’m currently driving for free! :)

I wrecked my Citroen C4 in meantime so it took me a little longer to burn first 40 l, but I was pleasantly surprised as my fuel consumption actually dropped a bit. A did little surfing and lots of people are finding similar results, so there must be something good about it, right?
Ever since I read about hypermilers and Wayne Gerdes in Wired I’m kind of obsessed with fuel consumption. Currently I’m doing 4.8 l / 100 km (~50 miles per US gallon) with OMV Sprint Diesel.
