Just drained 10 quarts of oil from my L8T

Yeah, I was planning on sending in another sample after my next change or two. My sample was from the old rinsed-out lemonade jug (rather than as it was draining out of the oil pan as they recommend), so I wonder if some water left over in the jug settled on top and contaminated the sample and affected the viscosity.

Chances are any water in the jug would have stayed on the bottom as is typically the case as oil floats on water. However and this is just a wild guess that perhaps the more volatile components as per gasoline etc might tend to float to the surface ( again only speculating ). I get the idea that these fuel injected engines are bad for fuel dilution when started cold due to lack of atomization at cold temps and that would add up if done repeatedly without a good heat cycle to burn the gas off. Like you said, next time you do a sample you catch it directly with the jar and have just turned off the engine after an good run time.
