While technically correct, in most cases there is little change due to daily temperature variations compared with seasonal ones. Most, but not all, tanks are buried deeply, and have significant "thermal inertia." The fumes one sees are much more dependent on the atmosphere than the fuel temperature. Of course, changing pricing from volume to weight, pounds, would obviate this problem. Commercial and military aircraft deal in pounds for this very reason. Temperature compensated probes already exist, and could no doubt be made relatively cheaply for non-aviation uses.

While the tanks are buried (and somewhat insulated as a result), the same cannot be said for the trucks transporting the gasoline to those tanks. As for Hawaii dispensing 234 cubic inches versus 231, that's a difference of 1.3% -- about the same as getting 3 cents off with a wallyworld discount card.

The temp of the earth at a depth of 6 ft. is about 55-60 degrees year round. Very little difference to the usual consumer.

This is a Dem. BS point to hack the Oil companies and always has been.

The place this temp is taken into consideration is in the huge above ground storage tanks you see at refineries and out on the ranches where it is produced. When a field gauger makes his round to gauge the tanks he takes the temp when he measures how deep the liquid is in the tank. At temps of up to 100 degrees in the summer, these 100,000 bbl tanks (4.2 million gallon) (one Barrel oil equals 42 gallons) can amount to thousands of dollars per degree.

So the government and the oil royalty owners are obviously anxious to make sure they get paid correctly. These temps are documented on all paperwork for tracking etc everytime it changes hands.

Even if this were true, it would mean that we get more gas in the winter. Are the plaintiffs suing for the right to pay more in winter?
