I'm pretty sure most CountryMark Diesel-R does not contain bio. However, some stations, like the one in Noblesville, sell bio in 5, 10, and 20% blends, but it's clearly marked and has a separate pump. However, I refueled at the station in Shelbyville and the Premium-R there had 2% bio, but it was labelled. Up to 5% is allowed by VW in the commonrail engines (and probably good for the HPFP). Also, you can always ask inside. Premium-R has a wear scar rating (lubricity) of 460 without bio anyway. We're fortunate to have an innovative company like CountryMark in our state. CountryMark has its own refinery in Mount Vernon, its own pipelines, and its own fleet of trucks. I don't use anything else. It's the only diesel fuel I've seen yet in the US that comes close to the Euro-spec diesel these cars were designed to burn.
