Will super unleaded harm the engine in my hybrid?
I use super unleaded in my Lexus LBX hybrid - will this do any harm to the engine? If not am I still wasting my money? Also when using the B gear position should I expect better mpg?

Using premium fuel will not damage your engine and it may actually improve its performance. The B position on the gearlever increases engine braking and is designed for descending hills, and should not be used all the time. Using this gear position may actually increase your fuel consumption, so we would recommend using the D position.

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.
