We'll I have never heard in 35 years that phenomena called fuel shear before?The normal reference is fuel dilution when raw non-vaporized fuel gets past the rings into the oil, but starts with what is called fuel impingement on the cylinder walls. Fuel that cannot vaporize for whatever reason has to go somewhere. This has been around for years, and is much better with fuel injection. However asking an engine to ingest more fuel than it's operating temperature can deal with negatively impact this: like being over zealous with the throttle when the engine is cold!
