I tried CRC 5-56 ** as a lubricant on my Ross Yoke Stirling Engine, as it was a bit tight in the cold cylinder, and it worked well, and I ran the motor for an hour or so, then put it away. A few weeks later I bought it out again, it was seized solid, I dripped a bit of diesel in, and left it a while, then gradually it freed up, after that I used the diesel, no more trouble.
** similar to WD-40
Tried Bolt Looser Lubricating Spray (Chinese, $ NZ 2 per 250 ml can), and Caterpillar brake cleaner spray, both these worked OK in the motor
