Supercharger oil has probably never been changed. Easy job to do. You will need 2 bottles of gm supercharger oil. You suck all the old oil out the plug in the snout and put the new oil in it.
Since I live in an apartment complex I don't have the means to do this until I visit my folks. This is where I do all my auto work now a days. So as of now should I check the SC oil level and top it off if needed?
