Written an unknown date in 1924 at age 29 or 30

The day was cold,

My car was old,

I cranked and cranked,

I prayed and pranked;

The engine would not go.

I primed and choked;

I purred and stroked;

I kicked! Boy, I felt mean.

And so I drained

What must have rained,

I'd bought for gasoline.

My neighbor said,

"Just use your head;

All speeders you can pass.

If you would test

The very BEST,

Refill with MOBIL gas."

My luck I tried;

My joy and pride

Is MOBIL: it's a wow!

To make such gas

That lets you pass,

Just MOBIL knows, and HOW!
