would like to know what is the best oil to run in a 4.8, i'm running a mobil 5W-30 semi-synthetic ,150 000km on the car and it has started to use a little oil, or do they normaly use a couple of liters per service is this normal.
cheers for any info!

Mine has used a little oil since I changed to 5W-30, got 165k km's. IMHO I think its too thin, but I ran 15W-50 which I thought was way too thick and made it run slightly rough.
The manual does specify 10W-30, and 5W-30 for Europe/European conditions only. Can go as high as 20W-50 in hot conditions though.
Mobil1 0W-40 is slightly thicker and maybe be a better option. I'm going to this on my next oil change.
FYI GL Lubricants in NSW seem to be the cheapest place to purchase Mobil 1 lubes, as well as Redline. NIck is a good bloke to deal with.
