Yesterday w/ my '65 c10 :

changed the oil/filter and lubed up everything. changed the air filter out, checked all the fluids and things while I was dirty.

major adventure : old grease gun started leaking the grease out the end, except it was in a liquid-y mess! Never had that issue before, I'm suspecting it's some synthetic-y lube, it's a reddish color... what a mess!

old trucks are fun!
