Calcium-based greases (calcium-sulfonate greases) are a bit more expensive
and have a higher "dropping" point (the temperature at which the oil
separates from the metallic soap). It's a good extreme-pressure grease. If
you have a machine that specifies its use, it would be a good idea to use
it
because pressure may be an issue. But there aren't a lot of such
applications outside of food machinery or machines exposed to salt water.

Wouldn't one of the newer moly (or other high-tech) greases work even
better, Ed?

I don't know. Besides the pressure, there is the dropping point, and
contaminant issues for several environments and applications. Unless you
study the subject a bit, it's a good idea to go with the manufacturer's
recommendations. If you don't know what they are, then it's worth studying
the subject a bit.

That sounds like good advice.

I haven't seen motor oil that was non-detergent for at least 40 years.
Maybe
for farm machinery or something similar. All of the non-detergent oil I've
seen is sold as machine oil and I've seen it mostly in mill supply stores.

I've been using detergent 30wt oil (Castrol GTX) in my mowers for that
long with no ill effects.

Mine gets mostly 10W-30...or whatever else is laying around. I figure the
old Honda will outlast me.

Hondas are well made, fer sher.
