How do we know since gas stations have these 3 or 4 in one pumps that if we are getting 93 that it isnt 89 or 97? Also how do we know if that the last personm that used the pump and used 87 and I put some 93 after ther use that some of the 87 isn't in there?
I think I am going to have to find and stick with the old fashioned pumps with there own individual station.

I've wondered this myself heres what I tried though see if it works for you.
Take the pump handle and squeze the trigger before you turn off the pump, mine was dry and only a couple of drop came out? It seems the hose is not holding any fuel, just my observations

Speaking of gas pumps, if you frequent the same station try to find out when the gas is delivered to the tanks. Make sure you do not buy gas that day or the next day either. When gas is delivered into the tanks it stirs up the water and sediment in the tank. It usually takes 24 to 36 hours for the water and dirt to settle back to the bottom of the tank.

so is that what they call bad gas?

Yes this is one of the ways water and dirt gets into your car'* fuel system. It usually causes problems art the most inopportune time.

That is good to know. I usually don't ever let my tank get below a quarter of a tank so I don't get any sediment in my gas line. I try to keep it 1/2 tank plus. I just drive 350 miles per week at least and then some on weekends so I'm surprised I don't have my own personalized pump.

Gas pumps don't hold gas after their pumps. That'd be dangerous, and cause problems. You'd realise it the second you filled up on anything less then 91 with the Supercharger.

just a side note, check the accuracy too! Wife fueled up our Bonney one day recently, tank was almost empty but it made it to the station with no trouble. Now we all know that we have 18 gallon tanks, so why did this one require 19.9 gallons before the pump clicked off? Station attendenant didnt have an answer for that one either LOL. I wouldnt have believed it if I hadnt seen it with my own 2 eyes

because the tank itself holds 18 gallons, but the filler neck can hold 1+ gallons of gas itself too..

it must have JUST made it in on the fumes then LOL.
