So was my dad, he drove his/my dart to Douglas Aircraft in Santa Monica till they merged with McDonald, then he drove to Huntington Beach. He worked there right out of college till they retired him.
Not sure of the content of green grease specified by Boeing for the 757 but there are 9750 grease fittings on the thing and some of those are impossible to reach on an overnight.
The exception is the brakes.
They specify a black grease and I assume it has molybdenum disulfied in that.
