Textron Aviation announced this week that three of its Cessna piston singles are now approved for select fuels designed for cleaner operation, provided operators comply with FAA Service Bulletins SEB-28-04 or MEB-28-01. The Cessna 172 Skyhawk and 182 Skylane are eligible to use 91UL (unleaded), 94UL or 100VLL (very low lead) fuels, “wherever it is available.” The FAA approved 100VLL about 10 years ago via a Special Airworthiness Bulletin. 100VLL has 19 percent less lead than 100LL. The Cessna 206 Turbo Stationair is eligible to use 100VLL, but not 91UL or 94UL.
