I would stay away from Kerosene. There is not enough lubrication properties in it to protect the pump and injectors. A good additive like Stanadyne, Redline, etc. will lower the pour point and provide lubrication for the injection system. Remember that MB's recommendations were made when all on-road fuels were high-sulphur and so cutting it with kerosene was likely not a big deal. I fear if you were to cut todays low or ultra-low sulphur diesel with kerosene there would be little to lubricate the injection system. If you absolutely had to do it I would recommend the running of some kind of additive and/or maybe some two-cycle oil to help with the lubrication. Our fuel systems were not designed with low sulpher diesel in mind. I always use some sort of additive both to add lubricity and antigel properties. Considering the low cost and effort of running an additive it is sheer folly not to, unless you enjoy paying for a new pump and injectors. The best thing you can do is buy fuel from a high-volume source if possible and use a good additive. Then you can be positive you are protected. RT
