Actually it comes (came?) in light (red cap), heavy (white cap) and extra heavy (blue cap).

No one outside the folks at CRC likely know the actual numbers...like most dampening lubes it's meant for comparison within that family of lubes so the actual numbers, in that context, are irrelevant. And CRC (like anyone else) isn't particularly interested in having customers experimenting or going outside their happy little product family so they aren't likely to release those numbers either.

Best anyone could do is make an educated guess based on how they compare with a known sample. I use the Shur-Lube set and it has the same non-issue "problem"...they're numbered 1-6, not by weight. No one's opinion is likely any more valid (in fact, probably less valid to your own use) than your own...buy a couple known weights and experiment with them vs. your CRC lubes if it's important to you.

EDIT: it seems Trev has an idea what they may be comparable to ^
