Ethyl Gasoline original vintage advertisement. Some hills here
- eh mister? Yes but they flatten out with Ethyl! You don't have
to wait for a hill to feel the difference Ethyl makes. In traffic
and in flat open country it pays dividends in a cooler, snappier
motor. You get more anti-knock fluid in each gallon than you
get in the best regular grade gasoline. Next time get Ethyl,
a better run for your money.
