Strange, the signature did show on my last post when I made it, but now it's gone. Anyway, no problem.
The reason I used PS is because that's the only antigel I had on hand. Even though it wasn't getting that cold where I went, I didn't want to take any chances.
Which brings up another issue: since lubricity is a non-issue using biodiesel, the "Slick-Diesel" component in PS isn't much use anymore. I used to use Stanadyne Performance but that was partly for lubricity, too. ARe there any additives that are just for biodiesel issues like gelling, moisture, algae, etc?
