Any one have any info on the k100d additive for diesel engines? I just came from the snowmobile show in Syracuse and they had a k100 dealer there. They had glass jars there with the k100,star-tron and another gas treatment. They had put a little water in each jar. The k100 stayed mixed even after it sat for awhile, the other brands separated right away. I figured if the gas treatment worked so well maybe the diesel treatment would too. The dealer gave me a free bottle of both the k100 and k100d and said to try my own tests. I will get a few glass jars and run my own tests. I will get a few common diesel treatments and mix with a little water. I will post pics and results on the forum.
