Fuel Consumption Optimax
Is there a clever way I can find out my fuel left? The opti smartcraft fuel gauge proves very inaccurate with my long thin tank, even at rest. Currently I keep a written log, noting fuel used whenever I fill up, and then look at the fuel used number before each trip. Subtracting one from the other gives me fuel used since fill up, and with a nominal 160L tank I assume 140L usable. This gives me fuel available. I fill up if my expected usage + 20% exceeds fuel available.
This seems cumbersome at best, and prone to error!
