So, we now have about 6,000 miles on the clock on our new LR4 HSE and there are some issues troubling me.
(1) Oil and Oil changes. I just cannot see waiting 15,000 miles to change oil! I did a change at 3,000 using Mobil 1 5/20 extended milage; according to mobil this meets/exceeds the recommended Castrol, which I could not find for sale anywhere, including the dealer. Now the questions:is a 5/20 oil really good travelling Death Valley in the summer with 120 deg outside temperature? Somehow I doubt it. I use Mobile 1 15/50 on my 1999 Range Rover under those conditions. Also, what is the oil usage I should expect on the LR4 5 liter motor? At the moment, it seems to use about 1/2 quart in 3,000 miles. This seems high to me; driving is mixed town/freeway. What do you think?
(2) Sport mode in the transmission. I generally travel in drive mode on the freeways, but occasionally I would like to use the sport mode which keeps the engine rpm a bit higher for a given speed and generally improves the driveability of the vehicle on curvy country roads. Now the issue. If I am traveling about 40-50 mph in drive, and then slide into sport mode, the engine revs to about 3,000 rpm and just sits there. Really, 3k rpm at 40 mph is a bit much. This does not happen if I start in sport mode from a stop.
Any input would be greatly appreciated.
