Very Good Full Synthetic Diesel Oil

This is a very good full synthetic Diesel oil derived from a synthetic oil base. People do not realize many synthetic oils are not derived from a synthetic oil base. You need to read the fine print on the packaging. *** Shell T6 is a Fully Synthetic Oil ***

Best oil

I've been using this oil for my 2500 diesel truck for the last four years and I put 4 to 6000 miles between oil changes and the used oil looks like the same color when I put it in new. Full synthetic. 15W 40 Rotella. I use oil filters for synthetic oil . Keeps truck working great !
