Winterization of 120

Post by Pack120 » Mon Nov 15, 2021 7:54 am

What process do you use for winterizing your cars - eg., a '41 120. Without an oil filter, is the process any different than just doing what we would normally do with a filter (except change the filter)?

What oils are you using?

How do you handle the issue of zinc and oil?

Any other considerations you can thinkk of?

Thank you.

Any name brand good quality motor oil today is far superior to what was available back then. And the zinc additive is really only needed for engines with very high loading on flat tappets, not particularly applicable to your car. If it makes you feel better use a ZDDP containing oil, it really offers no benefit, a quality oil of proper viscosity is more important.

When I was younger and winterized more thoroughly, I did the following.

Oil change annually in the fall so it winters over with clean oil.
Fresh antifreeze every 3 years.
Remove the battery and store indoors. Charge as needed.
Fogged the motor with a little oil down the intake while running.
Fill gas tank, add Stabil, and seal the tank cover or plug the vent.
Desiccant bags in interior. Moth balls if a wool interior.
Plug the tail pipe and seal over the air filter intake.
Wash, wax and cover. Vacuum interior and wax metal trim.
Over-inflate the tires slightly as an alternative to putting on blocks.
Block the clutch pedal down if stored in hi humidity conditions.
Leave in gear with parking brake off.
