The Land Rover LR2 has a recommended fuel type of premium unleaded. Does this mean it is required, or is it OK to use regular unleaded?
This is without a doubt one of the most frequently asked questions we receive. The answer will be in your owner's manual, but we know that sometimes the owner's manual leaves a lot to be desired. Land Rover says premium gasoline is the ideal fuel for the LR2, and it does not recommend using regular fuel in the LR2's 3.2-liter, six-cylinder engine.
This doesn't mean the engine won't run on regular gasoline, but Land Rover says the engine will knock — or ping; either way, not good — when using regular gasoline until the engine's computer adjusts for the lower-octane gasoline. When using regular, there will be less power available compared with using premium.
In short, use what the manufacturer recommends. In this case, it's premium gasoline.
