I've been skeptical of claims of damage by gasohol, but I've passed thru Tulsa and other towns in OK a total of 4 times in the last year. I keep real close track of gas mileage, and it always drops significantly (20% or more) on tankfuls purchased in OK. I suspect they are adding more than 10% ethanol around there. That will indeed start to damage lots of components.

Still, I drove thru there 2x in my truck, which has an Airtex pump, no problems.
