Odds are, the gas that is in the hose at the gas station is not the gas that you want. That part is technically correct. This video explains why it really does not matter to most of us. Not enough gas in the hose to make a difference, and has a neglibile effect on octane dilution. The math checks out.

 

Now there’s some news we can use!

 

Here we go..... 🙄

 

But are gas prices coming down???????????????

 

I get a few shakes on the nozzle to help ensure that it isn't going to dribble fuel all over my tank, but I don't look at it as any kind of cost-saving measure.
Anyone thinking the pump is ripping them off isn't realizing that the same amount of fuel in the hose that they didn't get, was there in the hose when they started pumping - that the previous guy left in the hose...
As long as air isn't introduced in the line, then the amount of fuel that passes through the hose to the tank is unaffected.

 

I'd be more concerned about leaving my gas cap on top the pump and riding off
