September RBOB prices took on a higher track during the overnight and early morning hours, registering a higher high in the process. Some traders indicated that a source of overnight support came in response to private inventory data late Tuesday that showed a slightly larger than expected draw in US inventories last week. Expectations for this morning's EIA report are for draw in the range of 2.0 million barrels. So far, the market has been able to overcome yesterday's weakness prompted by the restart of a BP refinery in Indiana.
