"I am doing a bit of research right now."

If you didn't see it, I put a comment towards the end of yesterday's DrumBeat which may be relevant. High Asian demand for naphtha may cause problems for the US this summer as exports from Europe are sucked East. It's also interesting that Saudi Aramco has apparently informed Asian suppliers that it will be cutting supplies of naphtha in the second half.

For anyone who wants to make their own (eyeball) judgement on the relationship between WTI crude and RBOB gasoline, here is the chart. It'll take a few seconds to load, and once it has done so drag the left hand side of the time period bar so the chart extends out from the initial 200 days to 658 days. Then look at 2007 vs 2006.

Brent may tell a slightly different story.

that is a very interesting chart with a very large spread opening up since Feb this year.

if only we could do the same thing for Brent and TAPIS oil price, which i think would track regional gasoline prices a little more closely.

Go back clear through 2006 and you see the exact same pattern as we are seeing now - as summer driving season comes along, the price of gasoline climbs above the price of crude and stays well above or just slightly below til roughly early August when if falls well below crude again.
