Incidentally there is some controversy about 10W30 oil because today's formulas contain LESS ant wear additives than they used to. This is because the additives poison the catalytic converters on oil burning engines. Today's engines with roller lifters and overhead cams don't require so much protection.

The result is some overhead valve, pushrod type engines with flat tappets are experiencing cam wear.

The precaution is to use Diesel oil which has the full load of anti wear additives.

Of course, good ol' straight non detergent 30wt has NO anti wear additives.

Your Packard is a flathead which should be fine on modern 10W30. But you could use an additive or diesel oil to be on the safe side.

There has been a lot of discussion of the transmission oil question. Some correspondents speak very highly of B&M brand non synthetic trans fluid. They report it cleans the trans inside, refreshes the clutch plates and makes the trans work like new.

It would be a good idea to service the trans and change the trans fluid to B&M in the interest of preserving its life and keeping it working perfectly.
