I’ve never seen a cop fill up at the gas station.
It depends on where you live, but a lot of large US cities have their own fueling stations. That way, the city can buy fuel by the tanker load and avoid gas taxes.
It’s both. Tax exempt paperwork is annoying, and one of the best ways to minimize it is to minimize the number of purchases that you make. Buy in bulk when you can, because one large purchase is less likely to have an error (or at least, more likely to be noticed) than a hundred small purchases.
If its government going through a vendor they are likely paying more than market rate.
Loads of pros
Tax is not insignificant, but they could already write that off.
No middle man for what little profit comes from a gas station
They can buy cheaper in bulk
They’re not impacted by shortages and outages they control their own supply
They’re not impacted by quality issues if a gas station gets water in one of their tanks.
They don’t have to track individual purchases for every tankful
No lines
Officers not vulnerable while fueling when they can do it in private
In many places they keep fueling gear in the garage where they park the cars and just refuel that tank with a truck from their own supply.
In my rural county the cops, school busses and basically all the public service vehicles like ambulances and plows fill up at the farmer’s coop, where farmers get cheap gas for their tractors. I have heard that this is not technically legal, because that has is specifically for tractors and has some kind of special price because of that, but I don’t know if that’s true or not. I know you’re not allowed to fill up your regular car there, but some of the farmer’s and cops do.
I think this is usually specifically for diesel fuel. Certain places have diesel fuel with red dye in it that is tax exempt. Any fuel you buy from a standard gas station has a good amount of tax baked into the price and it’s earmarked to go towards road and infrastructure repair. The thought process is, if you’re not using said vehicle on the road, you shouldn’t have to pay this tax.
So, they dye it red, sell it only at special places, and you get fined pretty heavily if you’re found using it in street vehicles. Typically it’s truckers that do it because most American cars (including cop cars) are not diesel. And I’ve never heard of this setup for regular gas.
I’ve lived all over, moved a lot, and have never seen a set up like here before, either. But, I’ve also not paid super close attention to farmer’s co-ops before moving here and getting chickens and ducks and doing small scale farming/big ass gardening. Lol. I assume they also sell diesel like you’re talking about. Maybe they just got a deal with the county and I’m/other people here are confusing that for the red diesel thing?
Still pay taxes even by the tanker. Can still get a lower price but fuel taxes are fuel taxes doesn’t really matter how you buy it.
