Check your operator's manual first, but this will probably work:

Amazon com Sewing Machine Oil Lily White 1 Gallon

This oil is available many places so you can probably search the internet for the best price.

...

If it is mechanical machine (NOT computerized or industrial), you can apply 1-2 drops of fresh, good quality sewing machine oil every place that metal rubs on metal. Avoid using 3-in-1, WD-40, cooking oil, or the oil can from grandma's sewing basket!!! Do NOT oil plastic, rubber, leather, or belts! Be sure to place a drop of oil on the bobbin race every 8 hours of use. Clean and oil the machine thoroughly every 40 hours of sewing use.

You should try to find a manual for your machine that will most likely have oiling instructions. Search the internet for: Manufacturer + Model + the word "Manual"

Because I expect you are using it for home use I will tell you this. Users of this machine may have a mess from the oil pan. Take the oil pan off. A man I worked on began to use synthetic grease on a regular time frame such as 100000 stitches. This prevents the mess from the oil pan. It appears as a powder but will adhere to the gears. I wouldn't use synthetic motor oil because it doesn't stick too well. Anyway, this is only a suggestion. The nice thing about this is it comes in a spray can at Walmart

What model is your Juki industrial machine?

Problem with sump or with sump screw? Or overly full?
I'm currently refubishing a Singer 491. To understand what sump and sump screw are, check out the YouTube channel of becauseimcrafty for their instruction on changing the oil. This demonstrates the large oli pan of a Singer industrial machine that is similar to yours as far as the oil "pan" or "sump" goes. TItle of their video is <<Industrial Sewing Machine l Changing the OIL>>.

Industrial sewing machine oil is usually not brand specific but is not interchangeable with automotive motor oil or thinner lubricants. Do not use WD40 or similar type lubricants as a substitute! Check with a local sewing machine repair shop or order online from Amazon.com (search for industrial sewing machine oil) This type of oil should cost less than $15 for 16 oz (before shipping)
