Exactly what oil is in the car? My Brad Penn (now Penn Grade) oil is a semi-synthetic with a high amount of zinc and phosphorus. IMHO and based on reading a bit on the subject.... First, a lot of the oils aimed at the old car, flat tappet market are synthetic or semi-synthetic. Some are...

It’s still just as green as it was before.

...Rod Muscle car oil. I am not saying to use Lucas exclusively, just saying this is the type of oil you need for old flat tappet cam engines. I use Lucas in clients cars as it is pretty easy to purchase up here. For my personal cars and clients that want it I have Brad Penn/Penn grade high zinc...

Gibbs GP-1 uses the same American Refining Grps additive package Brad Penn originally used. There's some conflicting info on whether Penn Grade uses the same formula anymore. I haven't used Penn Grade but the Gibbs is green like the Brad Penn was.

Brad Penn is now known as Penn Grade and that’s what I use in my classics. I order it though summit but it is also on the shelf at my Auto Value parts store. 30 weight would be what you want. My trans guy tells me ATF+4 and that I shouldn’t be picky about brands. I use dot 5 brake fluid as long...

Valvoline VR-1, Driven racing oil, Penn grade Are all great. Buy the oil made for the job, forget the ZDDP additives in off the shelf Modern motor oil. It has too much detergent and it fights your additive. many oil tests test the oil, then when thy put in the additive in the same oil the...

...probably not too different from Maryland where I live. I think your choice of oil is a little light as regards weight. In my 440s, I run Penn Grade 15W-40, and I use NAPA gold filters. Sounds like you got the right filter, but your choice of a conventional oil is not a good idea. Penn...

Penn Grade all the way!:thumbsup:

And there is my answer...

20W-50W was a popular racing oil for loosely fitted race engines back in the day. I probably would not run that oil in a street engine unless it burned a lot of oil with lighter weights. The Valvoline VR series of oils is available in several grades and all of them have adequate zinc. A...

Yes. Penn Grade does.
