Nice article, I do have one question though. I have been told, and admittedly have not experimented enough with it at 30 dollars a gallon, that higher OIL content actually will make the engine run a little hotter, while lubricating better.

Something about the alcohal in its unfired state cools, and the more oil, the less it cools. I know, this sounds wierd.

Also, when a car idles down, at idle, and then 10-15 seconds later, idles out, and stalls, this is actually 'loading' from the high end needle being too rich correct?

If you lean out the high end, then the low end could go either way. It could be too rich or too lean, so you will have to adjust accordingly.

Lastly, if the low end is too 'lean' will it rev up and out, or again, just idle stall. This low end idle is always the hardest thing for me to get to the sweet spot.
