Many different thoughts on this one.
Let's hear what brand of fuel you run, not the octane but the brand name and if you have a reason for running this brand.
To add to this topic, the one hose pumps that some avoid because of the possibility of low grade fuel being left in the hose from the last customer have a drain back valve in the pump that drains the remaining fuel from the last customer so you get basically what you pay for.
Feel free to leave your comments as well.
