We had tough winter here. Wile using polar power & some others jelled off 4 times.
Went back to stanadyne cold weather add.
Never jelled again. Proof in experience.
Sometimes we learn the hard way.
Had my big 40 injection pump rebuilt this winter, they sent me stanadyne add to use in it when got pump back. The guys rebuilding the pumps know what works. I did use Lucas till I learned the lesson the hard way. Now it's stanadyne only.
Thx
