On the 1999 Land Rover Discovery, you really need to watch for the trim level of the vehicle because the SD, SE7 and Series II all take different wipers. See Sources and Related Links below which describes it better than I can.
The 1999 Land Rover Discovery Series II typically gets around 12 to 15 miles per gallon in the city and about 16 to 20 miles per gallon on the highway. Fuel efficiency can vary based on driving conditions and maintenance. Overall, it is considered less fuel-efficient compared to many modern SUVs.
Standard recommendation concerning coolant for the Discovery are mid to high end brands. Regardless of brand selected it must be replaced every two years for maximum effectiveness.
