I'll post my observations of the alternator disconnect over on @CaliBenzDriver thread in the Tech Talk forum.

Of course it is! Why wouldn't you check? You don't have to use it, but for those that want a good 5W-50, that's a great price.

I had a Canada thing just last week (WAY WAY OT)...to fix a lithotripter in the US it is a $2500 repair. We ship to Canada it is $700...but, they can not legally ship it back....

The only thing I haven't done is to measure the oil pressure to see if there is any difference. Otherwise, it's fine.

I don't put a lot of miles on the cars, but I've had it in the cars for about 2 months now and probably 1500-2000 miles. It's been absolutely fine. The cars seem to like it. They start quickly and idle smoothly. I went from a 5W-40 to 5W-50 (both API SP), and my oil temps range from 199°F to 208°F when operating at full operating temps. Both oils were high quality full synthetic API SP rated, so I can't say there was any extreme changes. (NOTE: The Castrol 5W-50 is not MB 229.5 approved.)

ALT-LIN helps MOD-4....
ALT-LIN and MOD may well be having synergistic interaction!!! 
-- Variable pump pressure is used to detune the hydraulic VVT-Gear positioning.
-- We know oil pressure is affected by viscosity.
-- Running W50 affords effective protection against viscosity loss to operate VVT electromagnetic solenoids.
Engine adaptation to ALT-LIN so far seems to help bring the unstable engine temperatures under control (FAN OFF!!).
Meaning ALT-LIN could be proven help protect against viscosity loss.
This is still fresh... lets see how adaptations journey goes in relation to "normal" engine temps and fan staying off... Two birds one stone?

I keep avoiding this thread as I STILL do not have my new felt shield in my car from the hoses thing...once that is done I have a TON of catchup to do.

our engines for sure have a lot of heat even now in the winter my fan is switching on, so next oil change probably would be from 5/40 to 5/50

KILLER HEAT ... be gone!?
This means stock engine makes a ton of heat more than oversized radiator can remove.
Any positive factor to help is good, right?
What if you could experiment with :
- cancel extreme heat FAN:ON > NO-FAN!
- cancel high pressure heatsoaks
- cancel laggy throttle
- improve gas mileage
- reduce frictions wear
- limit tranny clutch sludge
- ....
Thanks to MBWorld contributors and experimenters
Video is interesting to watch once you understand this managed struggle. Hear the words solenoids, coils, heat...
Keyword: disaster.... 0W8 : LOL
-- next will be No1 Toyota: giant cost!!?
-- Daimler-Benz true leader has immunity.
