Corrosion protection, Coleman vs Crown fuels

Well, automotive gas is half what it used to be a few years ago. It could be that Coleman Fuel is expensive "New Old Stock" and the contracts for Crown are indicative of modern light crude pricing.

Who knows. I've got green Coleman in a one gallon can, pink Premium Coleman in the quart bottles, and several gallons of Crown that I picked up at the evil Walmart for $7.69 each. That's the cheapest I've found it since I've been married, going on 17 years.

It all works and I don't as a habit leave it stored in my Coleman stoves or lanterns, so it's all good.

I'd guess the only thing "premium" about the quart bottles of Coleman fuel is the price.

Someone gave me a half-full bottle that they had gotten from someone else. It burned just like any other camp-fuel.

 

One upon a century I had an abiding interest in old english sportcars.
It was observed that Penns—10w-30 left more buildup on sparkplugs than some others. Conversation suggested that there was more ash in that motor oil.
Ahah, crude is not all the same.
Coleman fuel, I have been using is exclusively since 1962 — before that it is what my dad used — seems to be made in Ohio — right near Pennsylvania. A state known for the lightness and sweetness of its crude oil.
Like vodka distilled many, many times eventually it is as pure as pure can be ( not what I drink but you get the idea ).
My guess is that for the same effort, all the while conforming to accepted standards ( like politicians), the lighter aspects of Pennsylvania crude vis-a-vis Texas is higher due to fewer contributions from other nations with thicker more asphaultic crude that is cheaper to acquire. Not all refineries are intended to function best on every variety of crude. We really need one in North Dakota to work with very light and sweet crude found there.
By the way, I still have the old red single mantle Coleman lantern from 1962 — works like a champ . . . Even though I no longer do.
