I have been using Stanadyne for months based on discussions on this forum and the advice of a local diesel pump service company. I am a believer. Today I was surprised, the Stanadyne I keep in the truck bed was frozen! I mistakenly thought one of the benefits of Stanadyne was to help the fuel flow in winter, along with the lubrication benefits and aiding with the filtering of water in the fuel. Yesterday it was -10 F most of the day and my truck was sitting in a parking lot. It started right up, but after a brief wait, battery charging at a normal rate and the high idle working I started my drive. Going up the first incline there was a major power loss, the little engine light came on and ther was no power above 2K RPM. Having a Hypertech tuner installed, I used that to clear the code, P0087, after which the truck ran normally. Could the Stanadyne have created the problem by freezing in the fuel line and plugging the filter?
