Unless you've got some super huge tank on a geo metro or civic vx, you shouldn't be going 90 days w/o a fillup. You also shouldn't get to ride in the top 10 for a year by having a good set of fillups and then just not entering new data... When I click on the top 10, I want to know who the best are out of people who are still actively participating in the site. Maybe others feel differently about this...
This my main compaint. I know i'm not active much but i see top 10 charts and see a one fill scooter or some low mileage fillup and never see person participating in forums. IMHO it's like they just like to see there naem at top of charts even if they know it's not the right area. I know i'll never make top 10 but still nice to see what people are doing that actualy post here and don't just join and make a gas log to see therre name in list.
I actualy get a lil happy to see someone with same car as mine and see how there doing.
My personal feeling is this... A 90 day average is just that. If you are only purchasing fuel once every 4 months, then when you fuel up you will be in the 90 day rankings for 90 days, then drop until you fuel again. If staying on the list is important then make sure you top off the tank every 90 days. I don't think that's too much to ask.
Well, if someone like that tops off every 90 days and gets smaller amounts, they will spend more miles dragging around more weight in fuel (which may matter more to highly efficient or insufficiently powered vehicles); and worse, they may not put in enough gas to qualify for the list, which shouldn't be based on 8 gallons in 90 days.
However, if you're driving so few miles (let's say 50mpg and a 14 gallon fill -- that's 700 miles, or under 8 miles per day) then your results are probably not meaningful to compare to those who drive ten times as much.
