Re: My oil ratio tests.

[Casey Lynn]

quote Jim Moffatt:

I will jump in the fray. I have been running a 1932 Fleetwin that was rated a 1 pt per gallon on 6oz per gallon of full synthetic. After each run I check the cylinders for condition with an internal light. Not only is there no scoring but there is a healthy film of oil all around them. MY tentative conclusion is that this ratio works well on all similar hp opposed piston engines. I realize that this is risky but I started with short runs and gradually lengthened them. I plan to continue.

For a long time I have been trying to find lubricity values for ordinary motor oil and twc 3 or ful synthetic oil. I just cant find them.

So let me get this straight.
You did not measure the bore to establish a reference point prior to your "Testing".
You did not measure the piston at the dome and skirt prior to your testing.
No photos of the piston skirt area on the thrust side for reference that you can check for change.
Your method is to simply look at the cylinder wall and see if it is scored.
And from this you are making a blanket statement that a lean ratio is okay for folks to run?
