My 3 litre Toyota pick up if fuelled up at my local garage on Romney Marsh will be half way up Loch Lomond before the little yellow light comes on, why on earth would anybody buy fuel on the motorway in 2020?
Assuming you mean a Hilux, that appears to have an 80 litre tank. My Yaris only has a 36 litre tank. Fuel economy on the Yaris will be better, but it's still likely to get thirsty somewhere near Carlisle doing that trip.
