TOPPING OFF GAS TANK. WHICH IS CORRECT. IF I FILL THE PENNY(S) TO NEXT NICKLE ETC. OR DOES IT MEAN TO CONTINUE TO FILL THE TANK AFTER THE HOSE CLICKS OFF.
Short answer,stop filling the first time the pumps clicks off(unless you only got a nickel’s worth in then you have other problems)don’t concern yourself with rounding out the dollar amount.
Don’t post in all caps,review you Posting Etiquette!
Review this situation in previous posts (there have been dozens)
If you check your owner’s manual, and maybe look at the labels in the glove box or under the fuel filler cover, you will likely see that the manufacturer of your car does not recommend topping it off. Topping off most modern cars can result in damage to the system and it often results in not being able to fill the tank easily.
Yea, filling to the next nickel is OK but don't try to get another dollar in there. If you are paying with a credit card, why bother at all. Also please avoid the ALL CAPS most people find it difficult to read.
“TOPPING OFF GAS TANK. WHICH IS CORRECT.”
If you are going to be driving through the Gobi Desert, then perhaps it might make sense to “top-off” your gas tank. However, for the majority of us who live near civilization, the ability to drive an extra 10 miles by topping off the gas tank is definitely offset by the probable damage to the car’s evaporative emissions system by consistently forcing more gas into the tank after the pump clicks off for the first time.
So–the simple answer is–when the gas pump stops, consider the process to be finished. If you are paying with a credit card (does anyone use cash anymore?), there is absolutely no reason to make the total purchase an “even amount”.
The definition is to keep adding gas after the pump clicks off until you simply cannot squeeze anymore in. Rounding it to the next nickle is not “topping off”.
Rounding to the next nickle is harmless.
Topping off can damage the charcoal canister in the EVAP system on some vehicles. Worst case, that can affect the ability of the tank to breath in and untimately cause operating problems and even premature failure of the gas pump. It isn’t worth taking the chance.
