Is there any easy way to tell which gear oil is yellow metal safe. I am looking for 80w90 to put in a tractor, and I can't tell which ones are safe and what isn't.
Most do not seem to say either way, does anyone have a list?
I can't afford expensive synthetic, just conventional from an "off the shelf" supplier. Possibly the Napa branded Ashland stuff? Tractor holds 5 gallons, so i have to watch the budget.
