Hi All,
Great forum, I've lurked for awhile but just now joined up.
I've been using Lucas Marine grease as my go-to for years. I use it in everything from my Volvo boat outdrive, Craftsman riding lawn mower spindles, Dexter EZ-lube trailer wheel bearings, to my New Holland tractor backhoe pins, etc. I went to grab a new tube today and noticed that is was now an OBCS (Overbased Calcium Sulfonate) rather than the lithium-complex I've been used to using. I'm worried because the 4 ball wear and the timken load lb ratings have gone down. Will it be okay for the shock loads in the backhoe pins and boat outdrive anymore?

So should I use the new formula or should I look into a different grease? Or am I overthinking it? I'd really like to continue using just one grease for everything.

Thank you.

Nope, the OBCS/polymer greases are the big deal today.

Amsoil uses a similar formula.


Science is about objective reality, not consensus.

In the case of the Timken load lb rating, higher is better. For the 4 ball wear number, lower is better. It means the wear scar being produced is lower. I think that is the way the numbers work. I could be wrong.

It's been this new calcium based formula for at least a few years now as that's the stuff I bought a few years ago when I replaced an axle with a damaged spindle.
