After reading several replies on "what time of day do you fill up", it got me to thinking, ...

Should you fill up the tank if you only drive in the city? It seems that if you are only driving a short distance anyway, you can save 50 or more pounds ov extra weight. (Fuel weighs app. 6.25 lbs per gallon. Don't put in 8 gallons, you save 50 lbs.) The problem I see is possibly water getting in the fuel through condensation, or extra dirt or other solids blocking the filter. Any thoughts?

I remember back in high school, a friend had a suoped up American Rambler. All us kids would pitch in our lunch money to put in enough gas to get to and from school. It was a blast to ride around in, but we never had enough money to put in more than 1/4 tank or so. Then in 1-2 days, another trip down to the cheapest station in town! Those were fun times!

I can only say that if 50# is considered as nothing, I then believe that I am glad that I don't have 50# of dirt or water in my fuel tank for the filter sack to hold back when refilling from near empty, (stirred up).

Then too, 50# of fuel at currant prices relates to near $18,00-$20.00 in cost locally (nothing) becomes an exaggeration cover sometimes. Stirring up any bottom dirt/water each time couldn't be good for any filter after those elements(debris) time after time get stirred about.

Per "I always run my tank down to empty" then top off......? ? ? Most primary fuel filters are ahead of those electric fuel pumps in the tank, secondary filters are sometimes in the line supply. Slowly getting punished..... aIsi Some things have to be renewed to be effective.

When you consider a car/truck weighs 4,000 to 5,500, and then two occupants add another 400 +/- pounds, what's 50 lbs? Nothing.

Since water and "dirt" would always sink to the bottom of your tank, I'm not sure why you think how full your tank is would effect your filters... (hint: it doesn't)

I always run my tank down to empty and then top off. I value my time too much to be stopping at a fuel station all the time to keep it full.

No, once I pass 1/4 remaining I start planning when to fill. Haven't run out of fuel since 1989 or so...

Never had fuel filter or fuel pump trouble, either.

Usually between 25%-75%. .5 to full is almost 100lbs difference.

No, I hover around 50% capacity and less with the daily driver, plenty of fuel stations locally/open 24/7. No need to always transport that extra fuel weight in a lighter daily driven vehicle for economy.

I generally keep more capacity in the tank for front/back traction balance when driving Winter season with an AWD vehicle.

basically, no.... run it right down unless I go by an exceptional price... may strategically take a half-fill, but may not have done that half-dozen times in my life

I don't keep it full, but I do top it off after it gets down around a quarter tank.

I never let it get below half unless long distance driving. It seems to get better mileage that way.

nice, jimbo, a tip of the carburetor to you... as for me, it depends... even if I'm at 3/4 I'll stop at a dependable "res" if I happen to drive by one... currently, with prices falling, I'm letting it run as low as I dare... last fill was 15.001 gals in a 15.9 gallon tank... probably too risky, but it WAS downhill to the lowest-priced station...
