How many gallons will a 1993 Chevy suburban hold?

The fuel tank capacity of a 1993 Chevy Suburban depends on the specific model (1500, 2500) and whether it has a standard or extended wheelbase. There's no single answer. However, it was typically in the range of 26 to 30 gallons. To know for sure, you'd need to check the owner's manual or the sticker inside the fuel filler door.
