I use half tank of gasoline in my chevy 2014 pickup per month. Is it better to maintain it between full and half empty or between half empty and almost empty?


More full is always better. Fuel systems are better sealed these days
but condensation was always a consideration. Ethanol added helps in
that regard too.

I usually fill at 1/8 to 1/4 but have to fill up every 5 or 6 days so
nothing collects.

Fuel has been improved too with better additive packages and filtration.
If you use cheap unbranded gas, use a top tier every few fillups and
you will get some benefits.
