Note GM 50' and today called for 0 NLGI Grade which is the real number you should be looking for. They had GS as a code part numbers and other items. The term "Grease" is too generic. why? look in previous post. Corn Head Grease is NLGI Grade 0 while regular grease most people think of is 2 NGLI thus referring to grease generally is not a good way to discuss this.
But food might
NLGI# Penetration Consistency Food Analogy
000 445 - 475 Fluid Cooking Oil
00 400 - 430 Semi-Fluid Applesauce

1 310 - 340 Soft Tomato Paste
2 265 - 295 "Normal" Grease Peanut Butter

4 175 - 205 Very Firm Frozen Yogurt
5 130 - 160 Hard Smooth Paté
