Old cranks on new BB squeak

Shimano 600 cranks from 1988 on new Sugino square taper bb are making a lot of squeaking noise. It's not the bb cups. Any suggestions besides tightening the crank arm bolt as hard as I can?

Grease the spindle interface.

Greasing a square-taper spindle isn't always the best idea.

I'm having the same trouble. IT IS THE CRANK BOLTS. I tighten them down, they loosen up, I tighten them down, they loosen up...............
After I tighten them, no creaking.
I was thinking of going back to the bolts from the old BB. They're tightened with a 14mm socket. There was never any creaking with the old BB with these bolts.
The new BB, Interloc Racing, has 8mm hex key bolts with rubber seals. I have a suspicion that the rubber seals may have something to do with the loosening. Before I put the old bolts back on I'll remove the rubber seals on the new hex bolts and see if that solves the problem.

I have had more problems with square taper BB's then most . Not to beat a dead horse, but from what I understand greasing spindle is a bad idea, and it makes sense why you shouldn't. Next time will definitely stick to external BB's.

I'm sure cottered cranks have their issues too.

I've had square taper setups that never creaked.

I think the problem I'm having is due to the plating on the spindle. The old spindle was not plated, super cheap, but the new BB is nicer, Interloc Racing, with a nicely plated spindle.
Next time I have it out of the bike I'll try roughing it up with some sandpaper. Although, I took some square taper BBs out of some old bikes and the spindles didn't have a scratch on them despite being well used.
They were Shimano BBs, a UN72 and a UN91, with pretty plated spindles.
The UN91 was in a "duraluminum" Alan cyclocross bike from the mid-90s and it creaked like crazy. I think it was due to the softness of the frame.
