Hi, I'm snoboy, and I'm new to the forum. I would like to say thanks for a great forum and I look forward to an education about oil. I hope I can contribute as well. I am a very small time Amsoil dealer but have been using it in every thing I own for apx. 4 years now. Is anyone running Amsoil High Performance 10w-40 oil in a 6.0 Powerstroke yet? I would like some feedback please. I am currently running HDD S3000 and getting great mileage apx. 17+ mpg unloaded and 13+ mpg w/ camper. I will sample oil in next few days, and post when I get results. the oil has apx. 5800 miles on it. I run a BMK 11 with a BE 100 on my 6.0. This will be an OIL ANALYZERS but I also ordered a Dyson kit from Blackstone. How long do they normally take to arrive? Thanks again... Mike
