does feul grade really matter, and other silly questions

[toddjb123]

The main reason that Land Rover requires premium fuel is not so the oil companies can make money but because premium fuel has detergents and other cleaning properties beneficial to good motoring. As a certified Land Rover technician I can, in some cases, tell when someone is not using premium fuel. In the long run it will become an issue. My 95 Discovery gets about 12-14 mpg and I will only use premium. If you want to play you have got to pay.

Thanks, Brutus! Good stuff.

So, can we run lowgrade and just throw in some fuel injector cleaner every once in a while?
