It's OK. I only clarified in case someone read it and tried it for their motors. Gear grease - Tri-flow or SuperLube hands down for me. My concern is the motor lube because it's the one that we're having trouble with at the moment - should we or shouldn't we use it? I'm also a little skeptical of the newly developed 3rd party lube since one of the companies is the one who "developed" a new screw for the pinker attachment and sells it for a lot. I just bought the same screw at Gregg Distributors for pennies.

I never thought much about the melting point but; grease have a few other factors that play a role. I have thought of it like this:
1. A sort of grittiness too smoothness factor; rub it between two fingers and feel the difference between a smooth grease like Triflow or a white lithium grease.
2. A gooeyness factor; how sticky it is and how it can slow down parts compared to a light flowing oil.
3. How well it coats the parts involved during use and how well it stands up to time.
I want something as smooth as possible, with the least amount of friction involved.
Well, this is exactly the situation I was thinking of. I just evaluated the wiring on a 15-91 (and topped up the grease tubes) and rebuilt the motor on the RAF - A 15-30 with what I suspect is an add-on motor.
I don't think the motor axle gets that hot. It shouldn't anyway if the belt is properly tensioned. Maybe I'll try to get one of these motors good and warm and see what temp it gets to. (or if someone else has that technology... since I have no idea what my availability will be for the next little bit.)
To be honest, the results were a little surprising to me. I'm re-evaluating what I thought about lubes.
Some people think the teflon might gum up the wicks. I haven't really decided what I think. I know in my syringe, the white precipitate (which I think is the PTFE or maybe it's the paraffin?) in the oil clogs the syringe a bit.
Somewhere, I've read that the melting point is important to the motor wick function. I'll try to remember where it is. Some Singer literature - I
think.

Well, I was stunned that that the original took so long to liquefy, especially considering a video I watched not long ago. That said, I can only compare to what I have and since most people say if you have the old tube and it's not all liquid or crusty, use it... I figured it was as good a comparison as any.
