Sometimes we have those little epiphanies in the shower.. sometimes they come from other places. This is a home for those epiphanies.

fill up on gas every chance you get because gas prices will only go up. (sh.itjust.works)

backstory is that i try to fill up my tank more when gas prices are at a low and less as prices go up to make my long term average cost per gallon lower.

now given current events, and empirical reality, gas has only been going up and will continue to go up. we could assume different curves(only constraint being that price per gallon goes up as time goes forward), but if you buy your gas now you will spend less money then you have if you bought it tomorrow, day after, or week down the road. my estimate is that it will be month minimum before it gets cheaper.

now that I have put this out there into the world you should fill up asap, I already filled up before making this post and other people will come up with this idea independently of me.

But then you're keeping your tank full, which is extra weight, which requires more fuel burn. To properly optimize, you should be calculating your exact fuel burn to get to your next destination and only put that much into your vehicle to avoid the extra weight. Lose all of the extra shit too, you only really need the steering wheel, gas, brakes, lights, engine, a couple of mirrors, the driver's seat, and a window to be street legal.

Now that's more reason to get jerry cans/storage tanks for the garage. Ironically the optimal amount would be close to empty tank in terms of fuel efficiency.

Running your tank below half constantly isn't always the best idea though as your fuel pump needs to be sitting in the fuel to cool itself. If the tank is run close to empty it isn't in the fuel bath anymore, it sits above it.
