Factory service manual for my mower calls for this grease but i am a little confused. I have lithium based grease in my grease gun but everything i read online for lithium greases say they are a lithium soap grease. Is the service manual calling for a lithium soap grease with no soap? I know its just a mower but i would like to use the correct stuff. Here is the part number for the grease in the service manual. https://www.cubcadet.com/en_US/all-products/alvania-grease/737-0168A.html
