115 miles and 11 litres to fill, with an 18 litre tank would give you a range of 188 miles or 301 km.
3.65 litres / 100 km is pretty good in my book.

Don't trust the light! The fuel sender is notoriously inaccurate. The bowser reading is the only true indicator.

Comparing the Thundercat with a Tornado is hardly a fair comparison. The Tornado capacity is half again bigger.
