OIL ADDITIVE
Some Hudson owners, especially those with splasher style engines use a zinc additive in their oil. Some had used GM's #1052367 but this product had been discontinued. GM's EOS (Zinc Additive Package) is again available with a new number, #88862589. Supposedly the change in number is because of a change in supplier. If you have been looking for this additive try the new number at your GM dealer.
**This is not a suggestion to use this additive, just a message on the change in part number.**
