Not trying to start a war -- just looking for opinions as to which oil would be best to use in a 2008 Sprinter 3500 with a Winnebago box on it (running full GVW, mountain roads, engine braking, high rpm).
In the past I always used Valvoline SynPower 5W-40, but after going thru the Mercedes 'BeVo' lists for their 228.51/229.31/229.51 approved oils I find exactly zero (o) in 5W-40 or 10W-40 weight available in the USA.
So, going on the assumption I'm stuck with 5W-30, and wanting to stay away from the ultra high-end 'boutique' oils, I'm considering both the Mobil 1 and the Rotella T6.
Both happen to be on sale right now at NAPA for about the same price, around $5.75 per quart:

Again, not looking to start a pillow fight, just wondering if there are any significant difference between the two.
