Stop athe Click (When gas nozzle shuts off)

“…that extra gas probably isn’t going to make it into your tank anyway. It’ll likely get stuck in the hose or the pump’s vapor recovery system, or just dribble on the ground as you return the nozzle to the pump.”

Really? Ain’t never had no gas get stuck in
Manyears ago as teens we wouldrain the hose. New nozzles will not allow that.

It is a different time, you aren’t a teen anymore, people rarely pay cash for gas, and your car’s vapor recovery system does NOT like you topping off.

So stop at the first click.


I’ve never found rounding up to be a problem. All within reason of course.
In the case of the pump stopping at 34.87 I would round up to 35.00. If it were 34.23 I would stop at 34.25 instead of 35.

Wife and kids have always done this with no issues also.

Rounding up 5 cents back in the early 70’s could dump another 1/6 gallon of gas in the tank. Rounding up 5 cents today - it’s less then 1/20th a gallon. Far less chance of doing any damage rounding up when gas prices are higher.


In any event, with most customers paying via a credit card or a debit card nowadays, there is really no reason to “round up” the amount on the pump unless someone is paying with cash.

I round up to the nearest nickel, $34.87 to $34.90, etc. A penny’s worth of gas is about half an ounce, roughly 0.46 ounces at $2.799. If I round up three cents it’s 1.37 ounces. My wife, OTOH, just pumps gas until it shuts off.

I admit, I top off habitually. Never had a problem with an evap system, never had to replace a charcoal canister. It’s my understanding on on most newer vehicles the hose that runs from tank to the canister is typically routed from the top of the fuel tank anyway, so the chances of doing any harm from topping off is minimal.

I have to admit that I always run the gas again after it clicks off; I have no intend to round up to nearest anything… I do it because in the past, on two separate occasions, the pump clicked off, and I thought it was full, only to get back on the highway and find the gas gauge reading no way near full. Yeah, I was not paying much interest to what the pump was doing, I was walking around the car, checking tires, cleaning the windshield, checking oil, etc… By the way, when I leave the pump handle on auto-fill; I do not set it at the highest setting. Made that mistake once and the auto shut off did not work and gas was spraying all over before I got the pump handle… And when I do the double fill, the second one is by hand and I’m listening for that sound of gas coming up the filler tube.

In the 1960’s the gas pump shut off valve was at the pump end of the hose, so a little gasoline was still inside the hose after the fill. I’d routinely see teenagers go to every hose at the gas station, tip the hoses and drain the gasoline, yielded maybe a 1/4 gallon of gas so they could continue their evening cruise. Nobody as far as I could tell, even the gas station owners, seemed to mind. Just one of those things teenagers did. 1/4 gallon of gas would have cost less than 10 cents. Modern pumps , the shut off valve is now at the car end of the hose, no way to drain it out.

1960’s cars, if overfilled, the gas would just run onto the ground. Fire hazard definitely, but not damaging to the car’s internals otherwise. A modern car overfilled, the evap canister and various evap system valves can get flooded with gasoline and damaged, and cause all sort of problems. Best avoided. The evap systems in modern cars do improve the overall air quality I expect, so its a worthwhile compromise imo.

Years ago answered a newspaper want-ad.
Older woman seeking companion to drive her car to Phoenix. (Then I would hitchike on to LA to find a friend’septic tank access cover under his lawn.)

I wasleep when she got off the planned route.
Awoke witho idea where Had to look athe stars to discern bearing.
Fuel gauge on empty!!!
Found a closed gastation and emptied hoses into her gas tank.
Coasted down grades iNeutral. Followed semis in their vacuum.
After midnight finally came upon an open gastation.


When we were kids (1960 or so…) and we needed gas for our mini-bikes, go-karts, or lawn mowers, we often raided the local gas stations to drain their hoses. And to think we used soda bottles and beer bottles to hold the gas… This was also the era that if a kid ever had a flat tire on their bicycle, every gas station would fix it for free.

After I started driving, I knew when a pump hose had been drained, when you turned on the pump, it would crank off a couple of cents, refilling the hose…

But luckily for me during that time, most gas stations just turned off their pumps when they closed at night and did not put a lock on the pump handle. I was driving home really late one night on my motorcycle. I had forgotten that I had run out of gas earlier and switched over to reserve. And as expected, I ran completely dry, even tilting the bike towards the reserve valve did no good…

So I start pushing my motorcycle home and it’s over 20-miles and back then there were no all-night gas stations, but I’m hoping… I figure I’ll run out of steam long before dawn and I’ll just have to wait for a station to open.

I make it to a closed station and I’m hoping the pumps were not shut off and I lift a nozzle and find no pressure, but then I remember I tilt the nozzle over, open the handle a bit and gas starts running out.
I’m able to get enough gas from their pumps to get to the next closed station, I do it again and only have to push the bike a short distance to the next station and do it all over again. I did get home long before dawn and swore that if I ever hit reserve again, I would immediately hit a station…

My '84 Sporster’s teardrop tank only holds a bit over 2-gallons and because I run my bike rich, I have about an 80-mile range. I carry two 1-gallon gas cans in my saddle bags when I’m out cursing with my friends and oddly enough, I’ve never needed to hit these reserves, but a couple of my friends are sure glad I’ve carried them…
