every true.
everyone should remember that the older V8 rover engines (buick) run really rich.
i am not starting anything, just wanted to point that out.
best thing to do is go by the LR rrc manual and what temps are in your state or country.
MN gets very cold in the winter and that is why i use 5W-30 and the summers get up in the 100's so i use 20W-50.
