Tim, is your Odyssey a N. American or the JDM/International version?
If N. American (you shipped it to Thailand), you need 86 octane, minimum. No more than 10% ethanol. NO methanol.
If JDM/International, follow the manual. I've always found refueling in Europe and Asia a challenge, because a single gas station can have many grades of gas, and figuring how much alcohol they blended is a real challenge.
