In my 9729, I use 30W Non Detergent oil that I bought at Pep Boys. That’s what the Grizzly tech told me when I ask what HL-70 oil was as recommended in the machine manual.

I have run out of the 30W Non Detergent that I bought from Pep Boys years ago, so I am planning on replacing the headstock oil with 30W Non Detergent Compressor Oil as others have mentioned. I will be going with the Mobil Rarus 427. For sure it will be superior to what I have used in the past, plus I can use it in my air compressor pump. I found a 5 gallon jug on eBay for $23.33 plus $5 shipping. Will never have to buy another jug after this.

I'd use straight SAE30 non-detergent oil. Avoid multigrade oils, as they use additives to get the higher viscosity rating, resulting in an oil that is actually inferior in lubricating properties to a straight grade oil.

I use Amsoil "Super Shift" synthetic transmission fluid.

I figure it's for gears in high-torque applications. And temperature stable for those mid-winter days in a cold shop. ;-)

What the detergent does in detergent oil is the same thing it does in your laundry - keep the crud in suspension.

That's fine and dandy of you have an oil filter, or in the case of the washing machine, a drain, because it means that crud isn't going to come back to haunt you.

Older cars (e.g. Ford Model A) don't have filters and rely on gravity (it's not just a good idea, it's the law).

Particles settle out into the pan and don't continue circulating. The oil change interval on a Model A is 500 miles with scraping out the pan every 2,000. Of course the oil they were using was only slightly removed from whale oil, but the important thing is it was non detergent whale oil :-)

If you use detergent oil and it's not a total loss system where the oil just flows thru, the oil will be holding onto the crud and running it thru your bearings.
