Re: Diesel Fuel Gel test - Pwr Srvc, Howe's, Schaeffer
Here are some additional pics on the water contamination test I mentioned I wanted to add to this post. Sorry it took so long for me to get this posted.
Many folks initially jump to gelling as being the problem during cold temps, but water contamination can cause problems much quicker than gelling. The water in these samples froze at the bottom of the containers within one hour.
Again, not a very scientific study or analysis - just a good visualization so we can get a better understanding of what might be going on inside the tank and/or engine.
According to the Standard, Diesel fuel can contain up to 100 ppm water. Most suppliers try to keep this under 50 ppm especially during the winter.
This is a #1 Diesel Sample with 2cc's of water added. The pic is a little fuzzy, but you can see the water droplets at the bottom of the sample.
This is a #2 diesel sample with 2 cc's of water added.
Here is a photo of both contaminated samples with Schaeffer's Winterized Dieseltreat additive that contains a water dispersent. It does seem that the additive was a bit more effective in the #1 diesel than in the #2 to the naked eye.
I'll add more info later. ran out of time for now.
