A few days ago I was towing my fiver through OK on the way to AR when I stopped at a Loves Travel Plaza to fuel up. I started refueling and then noticed a tag on the pump stating 15 percent biodiesel....
My 09 6.4 is only approved for 5% bio makes it difficult to find #2 in the mid-west states they all seem to have the up to 20% bio sticker. I did have to run it just to get out of there and had no problems....yet.
