I mostly make short trips less than twenty miles in 45mph zones.
Which Amsoil are you using? I may go ahead and switch over, as my cvt gets about 8 mpg worse than my identically rated Corolla that's been running Amsoil Signature Series for over 150,000 miles, with an average change interval of about 20,000 miles.
