I have a 1968 Charger and I rebuilt the 383 engine 20 years ago. I dont drive it much but I am wondering if using high mileage oil is better to help keep the seals etc plyable like they claim. At some point it will start to leak as after 20 years the rubber will become a little hard so I am wondering it this is a good simple preventative action that may help down the road. Of course it's not high mileage at all. I am wondering what you all may think.

Not needed with a fresh rebuild.

A quart of Lucas is known to soften the seals if they have hardened. Otherwise, not needed. Once you get to 75K miles on the engine then I would recommend using the "hi mileage" oils.

I’ve never used high mileage oils, even in 200k mile cars.

I use regular oil in both my old cars. Not worried about zinc as the possibility of excessive wear is slight under the way most of us drive our older cars. I change by year unless I happen to drive a larger amount of miles in any particular year. So usually every two years oil and filter are changed unless the mileage is really low for that period.
