It was stated that only turbo engines would need it. That is when I stated that the AFM is probably another reason. That was not intended to disparage GM, just state the fact that the AFM design has some flaws that crop up and probably needs a higher standard to oil to avoid problems.
You chimed in immediately defending GM with the million being bought and used without issue. I never contended that that was an inaccurate statement. I only contended that it might be a little myopic, and it might garner a negative response over at the some of the GM oriented forums, as problems are still cropping up related to AFM.
I did mention I disabled the AFM in mine, but that was for several reasons, the AFM issues being one. I am an old Cavalry Sergeant. I do not cotton to the idea that everyone doesn't have to pull their fair share of the load. I bought 8 cylinders, I expect them all to do their part, all the time. No union smoke breaks or acting like government workers where half of them will stand around watching the other half work. Nope, all the cylinders are going to work all the time the engine is running. It wasn't like GM gave me an option with this engine. Might have been able to get an engine without AFM, but it might not have been the engine I wanted. But disabling the AFM was an easy task done the day after I brought the pickup home from the dealership. Oh, and the daytime running lights and the seatbelt chime also got disabled.
I have no loyalty to any brand, primarily because there is no brand making anything that I really want. All I can do it try to get something that most closely meets my needs and does so at the best price. There is not a single vehicle being made today that really makes me feel all gooey inside and just got to have one. The last was a Jeep Liberty Diesel. I really liked that one. And for pickups, the '98 Chevy 2500 I had. But what is being produced today, I have no problem driving past a car lot and not even glancing at what is lined up next to the street and nary a desire to stop in. None of it appeals to me. Next go around will be like what I did when I bought my 2013 Silverado. Just try to find what will do most of what I want, is the most tolerable for me to own, and costs the least to do so. And that is not a bad position to be in, as I cannot be swayed by marketing nonsense in my vehicle purchases.
I've now seen you write you don't want any cylinders having a smoke break more times than I can count.
It baffles me completely that not only did you pay money to shut off the afm feature but the end result is paying more for fuel.
That is absolutely mind boggling.
Show me even 1 example of an afm equipped engine that wore out prematurely because of the afm or has is some way failed due to afm.
My charger has mds and I will say without a doubt that the feature has me now wanting everything I own equipped with it.
I just don't understand how you justify to yourself throwing money away,and burning more of it in fuel.
Oh yeah,no smoke breaks.
Truly the most absurd thing I've read lately.
Steve owns 20 of them,afm equipped and these trucks run all day powering the equipment in the van,so on the low end lets say they run 8 hours a day,just hours,not adding miles,then its driven in the city with all that stop and go,loaded to the max gvw and still he gets north of 300000 miles from these things,and no afm oil consumption related problems.
So there tired. Find us a tear down where the 4 cylinders that run during afm engagement are more worn and have caused premature failure.
Just proves that no matter how much real data is posted to inform some people get their mids set on something and they just refuse to accept any other information,completely stunting learning and then sharing these ideas.
I now understand why the syn oil is more slick myth still gets said. Because guys choose to ignore the obvious.
