All you have to do is meet or better the grade of oil that Land Rover said to use. There are a few on the market. I just finished changing the oil on my LR4. This time I bought the oil from my dealer. Total cost with the filter was $138.99. Never again. If you unscrew the fill cap on the engine, you will see the tube that runs down to the oil pan. You can buy a cheep syphen pump from Harber Freight for $7.00. It took about 10 minutes to pump the oil out. Platinum 5W-20 does meet the the standards. Good luck.
