Engine Oil

Hate to start WWIII, but is PennGrade SAE 40 high zinc and phosphorus used by Aers very much?

Not by me. 10-30 or 10-40 depending on what time of year. Zinc is not needed in a Model A engine.

Well stated, the perfect answer !

My engine rebuilder recommended Valvoline VR-1 high zinc racing oil, 10W-30. Given what I spent on the rebuild, I follow his recommendations.

My builder recommended Valvoline Racing oil 20W-50.

The guys at the shop that rebuilt my engine specifically suggested higher zinc level oil. I use the Lucas "Hot Rod & Classic Oil". Good price and no concern about the high pressure sliding surfaces on tappets and gears. Maybe the Model A does not have high pressures on the tappets? I do not know but I wonder how good the cam profiles were 90 years ago. Today's modern oils actually limit the zinc to very low levels and today's engines are made for that.

use a 10-30 or 10-40 that is all you need unless the engine is worn out. Zinc won't hurt anything.

Most stations used a service where the old oil was re-refined and re-sold as reclaimed oil. I doubt he ran dirty oil, there would be no good doing so.

Thats nice,you doubt a story told to me by my father..take a minute,think about that..

I just think he was buying reclaimed oil (drain oil that is re-refined) and called it what he did. Think about it. Why change oil if you are just putting dirty oil back in?

Your story is very authentic and was repeated over and over. My father owned a service station and was part of that process.

NOT unless it is need of an overhaul. But, IMHO, any oil in 2021 is better than any oil in 1928-1931. Over talked. Fill it drive it, change it.

I was told some time back that WalMart brand motor oil was recycled oil from Mobil.

I don't use it myself but a buddy does and has for a number of years with good results in his everyday Pontiac driver. Car has about 200,000 miles he bought it new and it runs fine

Do you walk with a limp? Likely so, because someone was sure pulling your leg! "recycled oil from Mobil"?? WalMart sells a LOT of oil! Where is Mobil getting all this oil to recycle, anyway?

Many moons ago when I pumped gasoline, the station owner had a 275 gallon oil tank in a back room. It contained the residual oil that dripped from every can of oil used at the station. The oil from that tank was sold as "bottle oil" at a lower price than the canned oil. This practice was common place back in the 1950s and 1960s. In my garage these days, I continue this practice of draining residual oil from containers.
