i dont usually let the fuel level below 1/4.the pinging occurs occassionally whether at full tank or half tank, however i noticed that below the 1/2 mark the pinging occurs more often and when the car is driven for about over an hour in stop and go traffic traffic. in driving short distances and less traffic routes, i hardly notice any pinging.
