1. Others can probably attest to this better, but you may be filling both the tank and the filler neck. The most accurate is the same fill every time.

2. I set it on slow and take the first click (more on why in a moment)...

3. #1 drawback is evaporative pollution (ozone). The fumes evaporate into the atmosphere to create this unhealthy pollutant. Secondly, your truck's check engine light may come on. It happens now and then, but there's something to filling too much and freaking out the on-board vapor recovery system and/or return line from the fuel injection rail.

4. Not much else -- just consistency is key to getting an accurate number.

1 - Is topping off a good/safe thing to do to keep an accurate record of fuel used?
2 - Are there alternatives to topping off to be accurate?
3 - Would there be be any possible safety/mechanical/other drawbacks to topping off?
4 - Any other questions somebody else might have........?
