A week or so ago, I paniced when I filled up both tanks with Bio Diesel before I realized what I had done. This is just a note to thank all of you who told me not to worry. We are now 2,000 miles into our trip and truck has run perfect. If I had not known the Bio Diesel was in the tank, I would not have been able to tell from performance.
On another note, truck had l2,000 miles on it when we left home. I put synthetic Mobile 1 Turbo Diesel oil in it before we left. Of the 2000 miles, at least l800 miles have been towing at max gross weight. I just added app. l/2 to 3/4 quart to bring back to full on dip stick. Is this normal for this engine to use a little oil?
