full tank. i religiously measure my fuel consumption kasi. besides, i allot a certain budget talaga for gas.

pag hindi talaga kaya full tank or bigla may out-of-the-plan na gamit ng kotse at hindi umabot sa next scheduled full tank ko, i usually fill up P500 worth of fuel which is around 1/3 tank (mga P1500 kasi full tank ko madalas).
