Drop in gas mileage is normal. Its the same if you excessively use premium with a motor designed around using 87 gas.
BMW and Mercedes Build Beta Products!
Lexus build Release Candidate Products!

Why does this matter?
CAUSE EVERY TIME someone says Lexus has better build quality, one should consider what Toyota their Lexus Engine and chassis platform comes out of and how long that part has been tested in the real world!
