lucas has a minus rateing for wear and is designed for both gas and d. The ford stuff is good and i us ps which you can get at any napa store. ps tested very good with a plus 14 or something like that and is cheaper than lots of the others. Improves mileage by 2mpg not towing. What ever you decide on make sure it is formulated for diesels only.
