Warm fuel at the gas station

[The motor guy]

Its not uncommon to hit 65-70 during the day and quickly drop down to 40-45 as soon as the sun sets during the winter in Texas. Anyways, this is the first time I've noticed this, but after dumping 27 gallons in my diesel truck just now I was like man that pump handle is warm! Then I go to feeling the hose and it's the same way lol. Makes me wonder how long it stays cold when things start warming up in the spring time. All these years of driving I've never noticed this

The ground temperature at 10 to 20 feet remains fairly constant in the mid 50's F +/-. So there should not be a lot of fuel temperature variance year around.

Ive heard the same thing about well water.

Doesn't most of the fuel sit in above ground storage tanks before being trucked to the gas station?

year ago a consumer program made about this subject. There was a minute difference between filling up @0C compared to 30; we are talking about a 50~100ml over 50liters

I know in the summer whenever I fill up a 5 gallon gas can its got quite a bit of pressure build up in the can a few minutes after filling. Gotta be careful when removing either the cap or the vent. Don't want any gas in your eyeballs

It's why geothermal can be a thing.

Fuel is actually a little bit denser when cooled down. Thermodynamics and everything. But there are a lot of variables, and there's probably no way to time it to get exactly the highest density. The temperature will vary with deliveries, ambient temperature, underground temperature, etc. and I've heard can take hours to change.

Ive heard it takes about 8 hours for the stuff at the bottom to settle after they drop a load. So that whole dont fill up when the tanker is there thing pretty much goes out the window

I believe commercial deliveries are temperature compensated so they accurately charge per unit weight. But an average gas station isn't going to care enough to do that.

If I see a fuel tanker @ a petrol station delivering fuel, I go to another station!

Why?

It’s all filtered at the pump.
