Engine lubrication

[roy keen]

I would not consider running a big block olds more then 4500 I think 4000 would be my limit not worth the chance of spinning a rod bearing.I also
wouldn’t consider o-20 oil over 15 -50 in our old tech engines. A lot of stuff you read these days is for newer tech engines but that’s just my
opinion.

I use Mobil One 15-50 and change with filter about every 2000 miles.

When I first got it I changed the oil, whatever I had cheap, and filter every 200 miles to get the crud out.

Hopefully cheaper than a eventual rebuild.

Also every year I drain about 3 quarts of ATF and refill with new.
And suck the master brake cylinder dry and refill.
