I had a 2006 Avalon - premium unleaded was required. Avalon’s engine at that time was built by Lexus division and installed on a Toyota designed and built frame with Toyota’s interiors. In 2013, a new redesigned Avalon was manufactured. While the engine borrows heavily from the Lexus division’s ES 350, the 2013 Avalon was made to use regular gasoline with 87-89 octane. Since the time of the 2013 model, Avalon’s engines run on regular gasoline
