When to refuel

They say to get it in the morning because it is MORE dense.

With underground storage tanks the fuel temperature is really not going to vary much unless they just got a fuel load in.

And I never buy if the filling truck is there.
I stirs up more of that bottom junk into the gas.
Let it settle out for awhile.
But of course, the truck could have JUST left and then . . .

It's filtered before it goes in. I haven't had to deal with rubbish in the tank for decades.

It IS filtered before it goes in , it is also filtered between the pump and the tank but every car tank I have ever seen has had some rubbish in it.

I read an article on this subject sometime within the last year--probably in the local newspaper. At one time, the temperature compensation was more of a factor than it is today in the US. The reason for this supposedly is due to more of a just-in-time inventory system the oil companies use now. Basically the gas doesn't stay in the ground long enough to get the maximum benefits of the ground cooling. If it were a major factor, you can be assured that the oil companies would charge for the additional energy.

However, the article did go on to say that gasoline in Canada does include some cost adjustment for temperature compensation due to the fact that it is colder there than in most of the US for so much longer throughout the year. Any of you cold guys know if this is true

that seems similar to what I remember from the article. However this says that the Canadian(en?) consumers won their battle over temperature compensation. Yay!!

Interesting, but that is a lot to take in... I've had the urge to do a little personal investigating on my own, especially with arguments that cheap gas stations pump less/inferior gas. It appears CA is like AZ: no temperature compensation... It would still be neat to do a comparison of local gas stations at different times of the day.

While there may be some creedance to that statement, I assume pumps suck from the bottom of the tank anyways. Logically, they aren't pumping from the top...the question is just how deep do they go?

Canadians "won" because retailers were the ones getting screwed. Canada is generally a cold place, so 1 gallon of gas there has more energy than usual. To prevent overselling gas, retailers fought for temperature compensation and won. Retailers = 1, Consumers = -1...

Hello -

Here's an article on the subject :

Oil Companies Are Using a Simple Trick to Bilk Consumers out of Billions - August 14, 2007.

However, I don't worry about time of day because of my schedule. Maybe I will record that in my fuel logs from now on.

I've been amazed in recent years at how little crap accumulates in Tanks.
I've puled tanks out of Supras (10+), 300z's (3), Mustangs, FireBird, Camaro, Accord and they have all been pristine. Which amazed me . .. (Average vehicle age ~12 years)

Now Classic car tanks; Don't get me started on Rusty fuel tanks . . .

pulled from another forum discussing fuel temp.


Actual investigative report about temps in underground tanks. Not supposition. Not speculation. And the pumps don't adjust for ambient, they charge you based on an assumed temp.
Go here, under "Featured Videos", "Hot Fuel":

more support for Temp does matter - although at the end - they state that when ever you fill up - you are probably loosing.
