So it's just becoming Winter here In the great white North And this is my 1st Winter with my 2022 powerwagon.

About 80% of my mileage is highway miles. getting to trips camping in wilderness etc.

Yet I have high idle hours. Not quite sure how this happened Completely, Yet I recently was I recently was sitting in the truck warming it up as it was 20 below 0. And did a search about the question above on Google.

It seems that the common Agreement is for every idle Hour, = 30 miles Of driving.

I found multiple videos those of Gasser's and diesels with very high idle hours being torn a part for rebuild And it was something else.

Also so for every the idle hour is = 30 miles a driving And every hour is the equivalent of 60 miles of driving.

When I did the math of total hours on my engine times 60 I was low, quite low. because of all the highway driving.

That is a very good thing for this big Gasser, Yes I have high of high idle hours so it's kind of a mixed bag.

I treat the engine as as if it was extreme duty and change the oil every 5000 km With an absolute maximum of 8000 km of highway driving that is. That equals 3000 miles and 5000 miles. I use amzoil only since new on this truck.

And I'm about to send the current oil well into amzoil for oil analysis as a baseline.

I just did it with a car I own And I had results within a week.

Anyway back to the topic, I'm going to be very curious to see what the oil analysis shows with the high idle time, If anything different.⁶⁶99ù9

Here are my numbers on the 6.4 l hemi

292 total engine hours

91 idle

201 Drive

With 15700 km or 10000 miles.

If you do the math for every Engine hours for 60 miles, it is 17500 miles.
It's going to be very interesting this Winter with Remote start when it's 40 below.
Going to try to keep the idle Hours down consciously.

Hmmm…interesting math.
Since all my idle hours are done with the transmission in park, they all equal 0 miles of driving.

I agree with MIKERU I just want some one to tell me with any technical data how MDS CAUSES any cam, lifter deteriation?! Oil pressue is oil pressure oil delivery is oil delivery. The oil pump delivers pressure PERIOD! weather the cylinder is getting fuel deliverd to it OR NOT and or if spark is available OR NOT. MDS
Has nothing to do shutting down oil pressure to variable cylinders. MDS does not shut down oil delivery to the cylinders that is not running.

I would like to know why they continue to put MDS on engines when there is no benefit to it only potential risk even when the majority of owners don’t like the feature at least according to the feedback on this site.

U.S. Govt. EPA-mandated corporate average fleet fuel economy standards. Auto makers are putting on ridiculous systems to shave every tenth of a percentage point off of fuel consumption they can.

Also ultra-thin engine oils, thermostats in transmission oil lines, and other crazy and expensive gizmos for the holy grail of EPA C.A.F.E. requirements.

I’ve searched and can’t find anything. Maybe stuff around that cylinder gets cold and tolerances get out of wack?
