Question: how much does it cost to fill up a jet ski?
Answer: Jet ski gas tank sizes range from 5 to 20 gallons, depending on the model. As a rule of thumb, an “average” jet ski has 15-18 gallons of fuel capacity, while gas prices are somewhere between $2.50 – $3.00 So if we do the math, it seems it costs around $40 – $60 to fill up a jet ski.
