So I read in the owners manual that it's a 15.9 gallon tank. Today I filled up and 18.03 gallons fit in it! Do gas tanks stretch with age????

No really, any of you guys fit more gas in it than specified?

I put 62 litres in my 60 litre tank.

I thought it was just the "reserve" section. I thin,k (keyword is think) these tanks are rated to just above the R marks. So in reality they are larger than what the manual says.

I'm just guessing here... :P
