Default Anyone using Shell Rotella T Synthetic 5w40?

Is anyone using this oil? I use it in my motorcycle and have for years. It is rated for diesel and gasoline engines and the thermal breakdown is amazing. After about 5000 miles on the motorcycle, it is at a 5w30 rating. I had it tested some time ago.
How well does it perform in the 5.4l though? The reason that I ask is that I am due for a change this weekend and am thinking of doing the Rotella Synthetic route.

Here are the stats from the Rotella website:

Default Shell Rotella T

Shell does not skimp on their lubricating oils - especially Rotella T of any grade.

Your motorcycle is by far tougher on a motor oil than the 5.4 would ever be. The bike gets hotter, there's a lot less oil in the crankcase that your truck and the transmission mechanically chews the viscosity index improvers like nothing else.

I had a Yamaha XJ1100 that was extremely sensitive to oil - as soon as viscosity breakdown occurred the transmission just would not shift from 1st to 2nd gear. I tried many different types of oil - including synthetics. As they approached 5,000km the transmission would become very hard to shift.

Rotella T 15W-40 was the ONLY oil I tried over 7 years of riding where the trans still shifted smoothly after the 5,000 mark. I still use Rotella T 15W-40 in a Suzuki 1200 Bandit which a own. Mind you this transmission shifts like butter all the time.

I use a 5W-20 grade of oil in my F150 because that is what the specs call for. I change out at 8,000km and the oil looks like it could go a LOT further.

I used to use Rotella T oil in my VW Vanagon for years; it had a high content of zinc (anti-wear agent), but like all the rest of the oil manufacturers, they lowered it because of the damage zinc will do to catalitic converters.

Don't have any experience with their synthetics.

I agree with Quat.Im sticking with the 5w-20 synth oil that I use in my 4.6 liter truck.Thats what the manufacturer says,they made the truck&engine.Ive never been comfortable letting oil go to over 5k miles on it regardless what it is.From the old school here....Pete
