I had a 77 Impala in 1980. It had a 100,000 city miles on it. It was used as a packout for a soda company that my father was the president of. They always had trash cars they were getting rid of and that was mine. People would follow the truck and unload the pallets of sodas onto the shelves and price them.

That car would not start. I always had a can of starting fluid handy to spray in the carburetor.

But 4 years before that I was already using it. Ether is a critical chemical for home chemistry but it is next to a possible to find, at least in a pure form that a regular person can buy. That's because morons use it as an actual drug and inhale it.

On the other hand, morons like me were using it to make a home made meth.

The most critical thing to look for in ingredients was to find no petroleum products in there other than ether. That would kill me quicker than the meth. I have no idea if they make it that way anymore and I don't care.
