Flashlike Ethyl Gasoline Promises Knock-Free Power
Since 1926 thousands of Texas motorists have relied on Flashlike Ethyl Gasoline to stop engine knock. The Humble Oil and Refining Company introduced this advanced fuel with tetra-ethyl lead to reduce carbon buildup, improve starting, warmups, and hill climbing, and to seal compression for smoother, more powerful operation. It is sold with Velvet Motor Oil and carries a three cent premium per gallon.
