I´d be concerned about usind a 5W 30 oil...

I dont know how road / driving conditions are in the US, but we got some mountains around here, the oil temperature could easily climb up to 250° F. I wont go on a -W 30 oil there...
If i would use a thin oil on my 3.0, i´d go with a Mobil 5W 50.

I use some Shell Helix 10W 40 in my Saratoga and the famous Valvoline MaxLife 10W 40 in my Voyager.

BUT.....i always have some lifter noise in cold condition....would a 5W oil cure that? I can´t imagine....

I also have to say....my engine has never been put apart.

I´ll overhaul it this summer, including all gaskets and maybe the hydros.
If i use a 5W 30 now, it uses about 2 quarts every 1000 KM.

After the overhaul, i´ll use some 5W 40 or 5W 50, the oil get´s a manly temperature if you travel across the mountains, i´m not sure about a *30 oil in this case...
