Author	Topic: Do you Top Off After the Auto Shutoff?	Post a Reply Back to Topics

Clint357 Rookie Author Indiana Posts:69 Points:159,110 Joined:Jan 2006	Message Posted: May 8, 2006 2:56:47 PM Ignore Clint357 Report Abuse My theory is that repeatedly milking the handle to get as much gas as possible in the tank runs the pump meter more than the actual amount of gas that goes into the tank. Do you squeeze in every last drop or quit when the auto shutoff quits? Today I asked the Swifty attendant to fill it up but not to top off the tank. He asked me again later to confirm I wanted a fill and I said yes but don't top it off after the automatic shutoff. So then I look back in the rearview mirror and he's topping it off. I asked him a third time to please don't top it off and he says, "I'm not, I'm just rounding it up to $38.00." After I'd already paid with a credit card so there was no point in rounding it off. Now I'm boycotting Swifty. It's not worth the aggravation to save a penny a gallon.

gassprite Champion Author Toms River Posts:1,087 Points:139,865 Joined:Apr 2012	Message Posted: May 6, 2013 3:02:50 PM Ignore gassprite Report Abuse Not a good idea to squeeze every drop you can into the tank. If it overflows it goes into the recirculation tube. Here's a more complete explanation I found. "Overfilling the tank risks damaging the EVAP system. The EVAP (or evaporative emissions system) is designed to prevent raw fuel VAPORS from escaping the gas tank and fueling system to the atmosphere. The EVAP system captures these vapors, and holds them until the ECM determines it can purge the vapors through the engine to be burned. But, by overfilling the tank, LIQUID fuel can be sucked into the system and damage the valves, sensors, and charcoal filter media used by the system. The system can tolerate a certain amount of liquid fuel, but, if you regularly overfill the system, it can get overwhelmed and give you DTC codes. And, with today's cars, most of these components are expensive."
