Disagree.....I wouldn't call it an LOL. Depending on the design of the specific filler-pipe and tank, the number of clicks on the nozzle might vary from vehicle to vehicle. But, as I said before, the main issue is, regardless of the number of clicks, NOT to overfill the tank or nozzle and cause damage to the evap-canister. I typically pull the nozzle out at the first click and hang it up...and it doesn't seem to affect my cruising-range very much, if at all.

 

I nor anyone else in my family have ever gone past the auto shutoff click lol!

 

Did you have the Hemi tick?

 

I haven't, ether, since vehicles first started using evap-canisters. Too risky.

And, even before the days of the canisters, some vehicles with horizontal filler-pipes would spit back on you if you overdid it, and gas would run down the rear bumper or fender.

 

Not going to go round and round, but your owners manual clearly says that you can top off the tank up to three clicks. It’s there in your own text you posted. You’re not disagreeing with me you’re disagreeing with your own owners manual you posted.

That was the whole point of what I said. American and Japanese cars allow for a top up within reason without endangering the charcoal canister, German cars do not. Which is why I told AJT that…since this is his first German car and he has a EVAP fault. German cars cannot be topped off even with one extra click.

 

just looked at the 21 4Runner. Toyota says do not top up the tank. Maybe becaus of the cap less filler it’s allowed on the Buick.

 

No, none of mine did. I changed their oil out on the dealer lot and then drove the hell out of them for 100 miles before changing it again. I never planned to buy the 17 but I got rear ended at a light by a guy going 70.....uninsured as they always are

The 17 had a freaking rust issue though and both front shocks failed at 31k miles and had a rear main leak at 33k. I was done with it and new cars in general at 37k

For me it was way too much expense for far too little, what really pissed me off was the warranty service being slower and worse than me just doing it myself

 

That's an interesting point, Jill...you may (?) be right.

 

I’ll have to look and see what the manual on my Lexus says. I can tell you all the Lexus cars I have had have been topped off and no problems have resulted.

My guess is most manuals say not to top off the tank. Every gas pump I have ever seen does.

 

I stopped topping off years ago as soon as I read that it's not great for the evap system.

Couldn't even tell you what the BMW does or doesn't allow. As soon as it clicks off, I put the nozzle away.

 

You should what TFL studios on youtube does when running mpg test. 3 clicks spaced between each other smh

 

I find it interesting.... I'm like the only person here to leave my cars on while getting gas (except for MB) and have since the stone ages and will until I drop dead, yet I never top any cars off and never have. One click and it's done.

The MB clearly says "Do not top off" on the gas cap or on the inside of the filler.

 

buy why?

 

but obvious. car keeps temp controlled for one thing. maybe someone is in the car while it fills. maybe a pet. maybe groceries like ice cream.

 

There's really no reason to leave the car running. I refuel with my whole family in the car with the dog and on a hot summer day and the car is off for such a short period of time it doesn't impact the comfort of the cabin since the fuel pumps are under roof. Certainly no ice cream is going to melt, and typically thats in the trunk where there isn't any climate control anyways if its a sedan. Nobody has ever yelled out "Daddy turn the car on!" to get the heat or AC running again, and believe me my kids are spoiled as hell they would if they were uncomfortable lol

In a 48v car or hybrid you could put it in accessory on and the HVAC would run as normal with no engine. Both our cars have that capability but it's never occured to me to do that because there's no need.

Like topping the tank off, there isn't any necessity in doing that...but people just do what their habits are. I ALWAYS topped up the tank before I got my first Mercedes, and I had to un-learn that. Thats how my Dad always filled a gas tank and thats who I learned to do that from. My wife always does it too because I taught her how to fill up a car since she grew up in NJ and had never done it before.

I have now trained myself not to top the tank off, but it took a while of telling myself when I started "remember don't do that" but now I don't do it in any car. My wife still does it, she never gasses up the Mercedes and it won't hurt the Pacifica.

I think leaving the car running when refueling is a bad idea mainly because the car can easily be stolen. Other than that I doubt there is any harm. If you've been doing that your whole life it would take a good several months of forcing yourself to turn it off before that too will become a habit.
