thanks for posting this as i will now NEVER travel through or into (SE Iowa) in fact maybe the whole state.

if my car ever got anything below 93 oct. it would stop running forever. lol
if i were u, I would buy the highest octane i could find and i would put a bottle of octane booster in every tank. refill the tank at the last notch just before the fuel light comes on,, the car will thank you. it will run better,, it will get better mileage,, and it will last longer. also it will have the power you bought it to have. jim
