What Grease To Use In Grease Gun?

There are many kinds of grease.
Depending on the usage or area, lithium grease, synthetic grease, food grade grease….etc are all perfect for priming.
Distinguished by the NLGI consistency number, it has 9 grades from grade 000, 00, 0,1 to grade 6. When the grade is higher, the grease is thicker.
