Will the older diesels do okay on the ULSD? How will it affect their mileage and power? Also, does the ULSD have any of the lubricants in it to protect the pumps?
Being in the market for a used CTD, I would really like some info on the above also....
The older trucks will run fine on the ULSD as it has lubricity improvers added to it.. One thing you need to keep an eye on is the fuel lines and seals as the ULSD may make them shrink and leak.. Also mileage and power will probably decrease because the ULSD has less energy than LSD..
I know that was true when the introduced the Low sulphur blends, but most newer vehicles shoudn't have this problem as the seals are no longer soley rubber. This is what I gathered from info when I was at the cummins and cat plants talking to some guys who should now best I think.
