Another oil "story"

Pretty interesting read. Looks like Valvoline and Royal Purple did the best.

I'm liking the Brad Penn cause I was a Kendal guy. But in the Fuel Car we use Torco !

 

Does anyone know what the load rating on Lucas Oil is?

 

I was thinking that too Mike. I'd like to hear what he thinks ?

 

I wonder how Amsoil would have fell into that group
or was it better than the purple so it was omitted

 

I also read this article with great skepticism.
As they "Street Commadores" stated this test only evaluates one quality of a motor oil. Hopefully someone with knowlege of motor oil design and testing will post more information on this subject.
However it has always been my understanding that one of synthetics weak points is clinging to metal as would be required on this type of machine where the oil film would be cut very thin by the pressure of the bearing on the wheel then this super thin film is subjected to shear, this would likely be the kind of load on a pushrod cup or wrist pin at startup. Conversly on a rod bearing the oil is forced in to the clearance under pressure most of the flow occurs near the bottom of the stroke and then as the crank pin rotates a wedge of oil is formed between the shell and crankpin and it is the oils ability to maintain enough film thickness to prevent damage to the shell.
Then of course there is cold flow, ability to carry away small debris, resistance to foaming, lubricity when diluted with alcohol, etc. etc.
