for me very simple lah, when u ride ur bike, always bring $$ for
petrol. If u know ur bike has tonns of petrol, and u're not going
on a far trip, no need bring much $$.
And for my pattern, i don care how many km i travel, when my tank
reach reserve, i suka suka pump $5-$10. Then i ride ride ride until
next reserve then i pump again.
Why worry abt how many clicks etc etc?? Crazy and waste time right?
Got petrol u go, no petrol u pump, thats my theory.. hehe
