In 2007, Hagerty decided to see if ethanol was truly the arch villain that rendered old cars fuel-leaking garage ornaments. The company partnered with Kettering University’s Advanced Engine Research Laboratory to develop the first test that closely duplicated a collector vehicle’s use cycle, with the goal of finding out exactly how these fuel systems were affected by long-term exposure to low ethanol–blended gasoline.
