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 only attempt to top my tank, most likely 6-8 times a year, usually when We are away from home and the price of fuel is much lower wherever, ETC. I then have about 3/4 + of a tank left, or more when back home, roughly 62% more left over than when I left home. I never run low enough to where the fuel light comes on, anytime.

I don't "keep" it any particular level but when I do stop for fuel, I don't generally pull the nozzle out until the tank is full. I also always reset my tripometer with each fillup so I can easily track my fuel consumption. I don't use the tripometer for individual trips.

Were I refuel the convenient time is early morning at least before 8 AM, early referring to after daybreak. Since using E-10 I've had no problems with other moisture in my fuel tank.

Recently buying diesel for utility use in a container, I spotted dirt on the pump nozzle(black grit) and wiped it off before starting the filling. The dirt looked like it came or rubbed off from a very dirty other vehicle's filler tube.>>> ? ? Not knowing/assuming with a watchful eye, I caught that before it entered my container.

Even a lesser amount of fuel always reduces in weight as you drive your tank back toward the E...mark, the 50lbs. gets reduced until the next refueling event.

Some fuel filters are more expensive to be replaced than ones in past years, so the objective it to not cause a premature dirt plugging of the filter, that can happen near the cap/filler door(often debris collects) often unnoticed there in that area.

No, only attempt to, often reach 1/2 tank is about average, that leaves room for a fuel price drop advantage. Advantage X 4 = roughly a $5.00 savings plus the >>> less inertia battle of the transport weight factor savings. WFMe!

Average is 33% full for mostly local jaunts, if price drops I may top it. Same for our other vehicles, price goes down I fill up everything mowing/garden utility containers also, that roughly is 50 gal. = 5 - $8.00 saved plus the less Fuel Tank Weight Benefit in mileage gain of stop/go driving(inertia thing)savings from motion Science of motion <<< check it out!

Yes, I have learned to do this, from "experience", the sort that comes from a "shortage of judgement".

Generally, I keep my tank at least half full at all times, providing a range of at least 250 or more miles. My vehicle has a somewhat longer range tank than most, but I have learned that earthquakes, storms and infrastructure failures can leave you with a need to travel on short notice, and often without the ability to refill. If you have yet to see the sorts of events that bear this out, be patient, odds are that you eventually will.
