Oil BT: Is Shell "Rotella 5W-40 Synthetic" OK for a 2.8L 30V?
$13/Gallon at Wal-Mart.
Not bad since Mobil 1 5W-40 Truck/SUV won't be available much longer.<ul><li><a href="http://www.rotella.com/products/rotella_t_synthetic.html">http://www.rotella.com/products/rotella_t_synthetic.html</a</li></ul>

Diesel-rated wax isomerate. Excellent for 1.8t and 2.8, but I'd rather use a hi-mi oil in the V6...
Synthetic is not needed in a V6. A Hi-Mi oil like GTX is just as good. Their 5w-30 is so thick as to me indistinguishable from a 5w-40. 5w-30 in winter and 10w-40 in summer, can't go wrong. Your seals will thank you. Rotella could go maybe a few miles farther, like 8000-9000 max verses a lil less for a good HM oil, like 6000-8000. Otherwise they both do the same thing with the exception of seal-conditioning. If you want a better synth then Rotella, get some MaxLife Synth.

last I heard there was some uncertainty whether the new 5w40 would be gasoline rated
