Default Worm Gear oil for older simplicity snowblower

I have a 1987 Simplicity 860E snowblower. I use it every winter but I have never changed, (or added) oil for the worm gear drive for the auger. I believe it needs to be a special oil for yellow metals but the manual doesn't seem to say what to use and I can't find anything listed for it by looking up parts info. A quick search online seems to be giving answers all over the place from gear oils, grease, engine oil, and syncromesh transmission fluid.

Any ideas?

Thanks for your time and help!

For what it's worth Simplicity calls it Roticul oil. A heavy dark brown consistency.

I don't know what Simplicity specified, but a quick smell test should tell you whether it's gear oil or not. It has a unique scent.

If it is gear oil, 90W GL-1 is safe for yellow metals. Avoid any other GL levels.

Short version: At some point they probably used steam cylinder oil, as that got more rare I suspect they switched to EP gear oil.

We used worm drive winches on shopmade well pulling rigs for years. They did have bronze worm wheels. In an inquiry with Braden winch years ago we came up with 600W gear oil. From memory, I believe they had origionally used a lubricant that contained lead, but that became an environmental issue. These winches were worked hard, many 10 to 12 hour days for years . I don't recall ever replacing a bronze gear, or a worm. Just had to service the brakes. For what it's worth this was our experience.

I have been a Simplicity dealer for 30 years. I called the factory when original oil was no longer available. I talked to the techs there and we all agreed the Ariens L3 lube is best alternative for them. Gear oil doesn't work because its too thick for winter.

At one place I worked, the boss made "snot" it was gear lube mixed with green grease just thin enough to be runny, but slightly thick. We used it in snow blowers and rototiller boxes and things like that. Put in a ketchup bottle to squeeze into the gearbox. Seemed to work, never had a failure on the equipment.

You might try lower end gear oil for outboard boat engines. The other alternative would be Snapper 'OO' grease, used in their snow blowers and brass geared mower transmissions. Both are not a hard grease, but are like a 'stiff' oil, similar to STP engine oil treatment in consistancy Both come in plastic tubes for easy dispensing.
