Where these numbers come from

Every chart on this site is computed from the tank's nominal geometry at 231 cubic inches per gallon, the same math your oil company's chart book uses. Steel oval charts include a 2.2 percent dished-head allowance, calibrated to the manufacturers' published capacity charts, so they line up with the chart books dealers carry. Real tanks still vary a little by maker and age, so treat any chart as a close estimate and cross-check your tank's data plate when precision matters.
