GAMI’s Roehl notes that “burning an unleaded fuel is just much easier on the engine. The impact of lead and its scavenging agent in the fuel are what cause problems with valves too.” He explains why GAMI has been involved for years searching for the right unleaded fuel formula. “We do a lot of things for the good of GA. That’s just the nature of our company. But we also have the ability to test octane performance in engines onsite. We have some unique industry knowledge about how to adopt an unleaded high-octane fuel, and we want to get the industry to recognize the impact of the problem.” When cars transitioned away from leaded fuels, he says, the interval for tuneups increased from every 15,000 miles to every 60,000 miles or more, not to mention longer intervals between oil changes. GA will benefit from those same advantages, he predicts.
