Was thinking of removing the left pedal and repacking it.. I found the left pedal loose and some of the grease pushed out. Would something like this be okay. WT-G Precision Bike Grease - 2oz. I’m not sure what’s a decent grease to use. Any suggestions?

I'm more of a cyclist than a rower, and am not familiar with the BikeErg, but here's what many (but not all) cyclists do:

1) if it moves, it gets grease
2) if it doesn't move, it gets anti-seize (especially for different metals which may lead to galvanic corrosion, plus a yearly cleaning)

If you want to pack the bearings in the pedal, that would be grease. If you want to attach the pedal spindle to the crank, that would be anti-seize.

https://www.parktool.com is a well-known and well-respected manufacturer of such items, although they're certainly not the only one.

ASC-1 is an anti-seize. HPG-1 is a grease. They now seem to have a PPL-1 as well, which is another grease. I don't know how it would compare to HPG-1, although both descriptions explicitly mentions bearings. If you have a reputable bike shop nearby and you want another opinion, just ask them. My guess is that either one would be fine for bearings. If you're going to repack the bearings you'll want to clean out the old stuff first, which is a separate procedure.

I've also used Lucas Red Grease, which can be found in many auto parts stores, although I don't remember exactly what I used it for. Probably a cassette or freehub, which is similar.

Another option is to just ask C2.

You can use any grease, whatever you have will work. It's just to keep the metal from seizing together. Just put a little on the threads as it will get pushed out when you tighten it.
