drops of medium engine oil added. The old style
D e l c o - R e m y distributor has a built-in oil reservoir.
Every 200 hours of operation, remove oil plug in base
and refill with No. 20W oil. Seal plug in reassembly.
The new style Delco-Remy distributor does not have
an external oil plug, since it is self-lubricated by oil

Every 100 hours, apply 3 to 5 drops of light engine
oil (10W), to the felt in the top of the cam sleeve,
