Nope, never. I once had the unfortunate experience when i was younger of gas spraying back on me from topping off too much so I’ve learned my lesson. I just stop when it clicks the first time. ---

[QUOTE=Qadgop the Mercotan] Nope. Fill until pump shuts off. No topping off the tank, it just wastes gas. [/QUOTE] Please explain how fuel is wasted. 😕 ---

[QUOTE=Happy Lendervedder] When you buy gas with your credit (or debit) card, do you always make sure that the total is an even dollar amount? [/QUOTE] It would never have occured to me to do this, and I can’t think of a single reason, other than whimsy, to do so. The only time I wouldn’t just fill up my tank is if I expect the price to go down significantly in the near future. ---

[QUOTE=kunilou] I top it off, round it off, even it out - whatever you want to call it. I do it every time. If I don’t the world as I know it will cease to exist. [/QUOTE] Yep, me, too - same line of thinking. And not just rounding it off, I like it to be an even number. $40.00, $38.00. I hate when it rounds out to an odd amount. I do it with my personal vehicle and my work vehicle. ---

I think the reason I do this (make sure it ends on a .00 amount) is because I expense my gas for work, so, in my mind anyway, I want to get back a nice round amount when my expense check comes rolling in. (It very rarely works out this way due to other things that end up on my expense report.) Plus, if I didn’t do it this way, the world would cease to exist. ---

99% of my gas purchases are at place I am a repeat customer. I do a different thing at each. I can instantly see if I was the card user and if not, at which place the crook used the card. ID theft and CC ripoffs are a real PITA, ask those who have suffered. We have so little $$$, we have to be ANAL about it. ---

I specifically pump an uneven dollar amount. Fifteen years ago, before pay-at-the-pump was prevalent, I frequented an Amoco station and paid inside. Someone there sent through a bogus transaction for an even $20. When I reviewed the monthly statement, that number stuck out like a sore thumb. Even though I rarely pay at the cashier anymore, I still pump an uneven amount. ---

[QUOTE=Happy Lendervedder] When you buy gas with your credit (or debit) card, do you always make sure that the total is an even dollar amount? What I mean is, do you “top off” so that it’ll come out to $23.00 as opposed to $22.87? [/QUOTE] No. I pump until the handle clicks and that’s it. ---

Nope. When it clicks, that’s sufficient. ---

What I mean is, do you “top off” so that it’ll come out to $23.00 as opposed to $22.87? I do so, obsessively. My wife, not so much; and she laughs at me because I do it. You? [/QUOTE] Its OCD, but its harmless in this form. No one gets hurt; no money is wasted, etc. Its just a way that your mind has found to get rid of stress. ---

[QUOTE=amarone] [Not true.](http://www.epa.gov/donttopoff/) [/QUOTE] I did not know that. I almost always go for the second or even third cut-off. Not to round off the figure, but just to fit more petrol in because I know it will have gone up by another 2p a litre next time I fill up ☹ ---

I almost never do. When it clicks off, that’s it. The only time I aim for a certain amount is when I am filling a gas can for the mower. ---

I just filled up my van. Just pump 'til the pump clicks off and that’s it. ---
