Stupid oil / grease question

My manual windlass has an oil reservoir and a plate that says to fill with "Oil Grade SAE 140 Or Nearest" I'm not familiar with what this is.

Where would I find this...an automotive store? No luck at WM.

Re: Stupid oil / grease question

Oil is not stupid and neither are questions.

5W oil is very thin
30W oil flows
90W oil might go in a manual transmission gear case, it is pretty thick
140W oil might very well be a good grease

Re: Stupid oil / grease question

To add to Caleb's good post..

Looks like a heavy gear oil.. IIRC most differential case oil is SAE 90 - pretty heavy compared to motor oil already... so this is going to be nearly grease.

Re: Stupid oil / grease question

Google "heavy duty gear oil" and you'll find sources online for purchase.

Re: Stupid oil / grease question

I have only found a multi-grade so far:

Lucas Oil 10042 SAE 85W-140 Heavy Duty Gear Oil

Think that will work?

Also, I found a manual on-line for the windlass (a Simpson-Lawrence Hyspeed) and THAT says

Automotive Gearbox Oil SAE Grade EP80

Which, seems to not agree with the tag on the windlass.

What would you use?

Re: Stupid oil / grease question

Get a quart of SAE 90W gear box oil and try it out. It is close to the consistency of honey or molasses but will still flow slowly. Won't cost that much either at Napa or similar.
I'd believe the manual more than a random tag attached to the windlass.

Re: Stupid oil / grease question

I would go with the multi grade but SAE 90 W will work you aren't dealing with high speeds or excessive loading...

Single grade oils have generally been superceded by multigrades, which have viscosity modifiers to reduce their tendency to get thinner as they heat up. I don't think you'll get any wear problems with the multigrade oil, but I do wonder if you'll have trouble with it pouring out of the winch when you're on well heeled on a tack, as the multigrade is thinner when cold.

Re: Stupid oil / grease question

gear oil is 80-180 wt--- 140 is a mid weight gear oil and will be found at napa or auto zone, mebbe. wallys wont have it----nor will costco.
lower end unit lube could well be what you need, if it is proper weight.
