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

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

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

Re: Engine Oil
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.

Re: Engine Oil
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.

Re: Engine Oil
They were not changing oil, they were adding a quart to stop the engine from seizing up. Times were tough, think about it !

Re: Engine Oil
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.

Re: Engine Oil
Back, before they put detergents in the oil, a lot of people put used oil aside and let it sit for a few weeks. All or most of the contaminants would settle out and "clean" oil could be scooped out for re-use.

Re: Engine Oil
The guy I worked with does somewhat the same thing. He drains the oil from each container into his oil cans. When adding fresh oil to an engine, I let each one drain for a while before adding the next one.
