Question for 33 gal. owners

[HemiDude]

Just curious, for those of you with the 33 gal. tank and don't put a lot of mileage on a regular basis - do you fill the tank full at every fill up, or partially?

I don't put a lot of miles, and wonder if letting all that gas sitting in the tank for long period is good.

Thoughts?

If I'm not going to be out on the road, I put gas in at 1/4 tank, stop at 3/4. No point in carrying extra weight if I'm going to be doing mostly stop and go. If I'm traveling, I just fill it up before I leave and again in 500 miles. Like that 33 gallon tank!

I haven’t needed to get gas yet.

Ive got a 3.21.

Prob just get a quarter tank when needed.

The extra weight argument is kind of pointless, IMO, unless racing whee every pound counts. 1/4 tank is what maybe 5-6 gallons. That's like 35lbs.

Image if you truck struggled due to an extra 35 lbs of gas, LOL.

With the standard tank, I can go to the cottage and back, on one tank, if I don't drive around at the cottage much. With a 36, I can drive a lot, and still make it. Plus I check Gas Buddy to see where it's cheapest along the way. When I can save $.50 a gallon in one place on my route over another, I fill up. I don't have to pay the higher price, because I drove 75 miles, while up there, and can't make it back to the cheap station.

I disagree (kind of). My work route: 45 mph to stop light; 45 mph to school zone; 45 mph to stop light; 45 mph to stop light; 50 mph to stop light; 35 mph to 4 roundabouts (which may as well be stop signs since people can't figure out how to navigate them ); 35 mph to stop light; 35 mph to stop light; 35 mph to stop light; 25 mph to facility. Reverse and repeat daily. Some days traffic is light and it takes 15-20 minutes, other days it can take 30 minutes.

The 50 pounds that isn't in the 1/4 tank (1/4 of 33 is 8+ gallons) when you drive stop and go to work and back everyday certainly accounts for something. It's not like the truck struggles with that "extra" weight (esp with the 3.92 ), but it is basic physics. Besides, my wallet is happier adding only half a tank at a time

You're an engineer aren't you?

Not formally, but I did sleep at a Holiday Inn Express last night

Seriously though, my truck gets 14-16 mpg in town. I'm not complaining- if I cared immensely about fuel economy I would buy a prius. I'm also not oblivious to that fact that more mass requires more energy to overcome inertia, so lightening the load = better mpg. Geez, that sounded like I'm auditioning for a support panel of bidenomics.....

1/4 tank of 33 gallons is ~8 gallons, but we all know the gas guage doent read in exact inrememts, and you will never get 33 gallons into the tank if it gets to E. The truck would barely notice 30-50lbs of static weight. At least not that you would ever be able to measure without going to multiple decimal points. And you weren't only one talking about added weight of a full tank. You just happened to be the last comment that I replied to. So not picking on you specifically.

Don't you think that if the first paragraph is true, then filling it up to full every time is also going to be saving fuel because you don't have to pull in to the gas station and stop and get rolling again twice as many times? One less slow down/stop/accelerate because you had a full tank instead of a half a tank is going to save you fuel.

That's my thinking. Even if the gas won't go bad by the time I reach 1/4 tank, why lug around extra gas, which equals extra weight, which equals less MPG? I know we're not talking a lot of weight given these are 5.7L HEMI who can which a haul and tow a whole lot more, but still, extra gas is extra weight. What for? I have gas stations on every corner...

Have you calc'd up the weight of all of your mods?

I've never worried about the extra weight of topping off the fuel. If I was worried about extra weight, I'd remove my Diamondback HD cover and save 200lbs.

And, since we're all so concerned about saving weight, how about those extra pounds we're all packing? I know I could stand to lose more than a 1/4 tanks worth of weight.

Do the math: subtract your ideal weight from your actual weight and then consider all the deceleration/acceleration we demand our trucks to execute with all that added heft. Can you imagine how much fuel you'd save at your ideal weight? [Enter 3.92 comments here]

I sure don’t want to save the little amount of money (carrying less weight) to have to stop more often to get gas.

Thats the whole reason everyone loves a large gas tank - less time wasted, hassle, and longer range…

Yes it does account for something. Requiting you to go to a gas station and waste gas and time getting gas 25% more often.
50lbs is not going to reduce your MPG, these are not 50 horsepower trucks, there is more then enough power and 50 lbs is not going to affect how many mpg you get, you are not running the engine at 500 RPMs in motion.

I have filled up to 32.4 Gallons. I was basically running on fumes.

In a nearly 6,000 truck, the 50 pounds of gas is .8% of the trucks weight. That's about .1 MPG max. Since that is burnt off in that first quarter of the tank, it cuts about 2 miles off of an entire tank. My time stopping extra times to fill up, is worth more than the savings of driving with my tank partially full. And by filling my tank at the $.50 a gallon cheaper station, it would cost more to only get half a tank, then get another half a tank where it's $.50 more.

My 1500 weights more then 6,000 even without me sitting in it.
33 gallons of gas weighs around 200 give or take a little depending on the temperature...
If I fill up only to a half a tank I can go from 6360 to 6260. It would make no difference

You ordered an fully loaded Rebel. You can forget getting any kind of good mpg, that will get even worse then my Limited. Wrong choice of truck if you were concerned about gas. Maybe cancel and re-order a Bighorn or Tradesman with no features (as those add a bunch of weird way more then a fuel tank).

Damn, you have a fat pig. That etorque must add a bunch of weight. My 2020 Built to Serve weighs 5700lbs without me in it.

Of courses that was before the new front bumper.
