130-AA.... This grease will wash off with gasoline. It will work with propane or natural gas.
Your best bet would be to replace the valve for $55....

Having tried many of the lubes listed herein the easiest was a drop of 100LL every time the cap came off. Grease, EZlube and others washed off after 4-5 flights and back to dropping fuel. So . . .
I did a little research on the solubility of DC-4, DC-2, EZlube, Lubriplate Lithium, and many others in 100LL. All were soluble in gasoline
I finally found a pure PTFE product called Krytox GPL-205. It claimed not to be soluble in gasoline so I cleaned the caps and o-rings then applied the Krytox. Three BB sized balls and worked it around. A tiny smear on the pivot too.
8-9 flights and three fills to tip top and it the operation is still butter smooth. If this works, a small tube will last till TBO.
BTW - a 0.5 OZ tube was over $20, so not the cheap solution but hopefully it is lasting.
I think I need better bait. It's clear many people don't read past the first sentence. With this lube, the cap does not stick and need the press after lifting the tab.

Just a couple of drops of gas a couple of times a year seems to keep my caps happy. EZ Lube, etc. is just too sticky for this use.

Nothing seems to dissolve that stuff. Rubbing it off is the only way I've found. Miserable stuff for this application.

I used isopropyl alcohol and naphtha (separately of course) to remove all residual as I has tried several things in the past year. I'm not sure which one is good for EzTurn, but between the two and the rubbing, the o-rings were clean.

THIS is the best tip in this entire thread. Lift the lever to the vertical unlatched position then while holding the lever in the vertical position, push it straight down "into the gas cap". I tried this for the first time yesterday and it worked like a charm! The cap then comes out of the tank with zero resistance!
