Just because they are both made from oil, and sold in similar quantities does not make the amenity or shop similar. 

This is about people's expectations.  

A toilet and a drinking fountain both involve fixtures that use water, yet tagged separately. Same with water point, tap, bidet, and other water based amenities - because people's *expectations* of what is present would be broken if I tagged a drinking fountain as a tap or toilet. 

That's the point of this is discussion.

If I saw a car parts icon listed in Africa, and I need to get parts for vehicle ( even a single can of motor oil) - and I went to one of these shops, and there was an old lady selling gasoline for scooters in whiskey bottles out of a window in their house, I'd think the tagger had lost their mind and delete the shop. Similarly - if the tagger tagged this as a gas station, I'd think they are joking. 

I don't tag granny's roadside vegetable stand as a market nor distribution warehouse - but that is the same thing you are suggesting - but in some places it might be a permanent and expected way for some people to get vegetables - so how do I tag it? Do I pollute market when it is a table with 10 green onions and a few eggplants? They are a farmer, so is it food distribution?  Neither works, so a new solution should be found (for this example). 

Go look at my kerosene tagging example, and tell me what tag you would put on a gas station that doesn't actually sell gasoline or any fuel for cars. Should you like to further dilute petrol station tagging and include those too? 

If I see a gas pump icon, and thanks to the renders and data users, I would see a gas pump icon in both cases, it would make me very pissed to show up there with a car expecting 50L of gasoline.
That's what we're trying to avoid.
