What i've read Highlander and it was 64 pages long lol, all diesels would benefit from the extra lubrication due to our poor quality diesel but i'm a little concerned about using it common rail diesels as they're apparently designed to withstand our diesel.

If you have a spare few days give this article a read it's quite interesting.
