Hi folks. We purchased our first diesel truck in February. A 2014 Sierra 3500 HD. I've been reading a lot about diesel trucks as it pertains to pulling a trailer, but what I haven't found is info...
My 10 year old PowerStroke was rated for B10 and the new Cummins is rated for B20. The PowerStroke liked the additional lubricity of biofuel over the low sulfer offering (even when I added cetane) - It ran noticeably quieter.
