Where is everyone #5

Sounds like my oldest in her late teen years lol. Everyone says how rewarding parenting is and blah blah blah, but at this moment in time, I really feel like the last 20 some odd years have been a complete waste.

 

Some things are better left unsaid.

 

Good evening from Muskogee...

 

When my daughter was little and in the potty training phase she, too, became odd about the #2.

She wasn't afraid of the toilet, she was afraid of going. She'd hold it in for as long as she could which wound up in things so large that passing them was a painful, tear filled experience. So it just reinforced the fear. We wound up having to start giving her juice dosed with powdered fiber so she'd stop holding it in.

 

We've had very little trouble out of the after treatment system on ours, and zero engine problems, 621k miles.

A few basic things that guys with these engines can't seem to comprehend is why they get a bad rap.

Idling for extended periods of time causes soot to build up in the oil, soot is abrasive, abrasives in oil destroy engines. "But the guy at the dealer said it was fine if I bump it up a little." Seriously, that's the answer you get when trying to explain a very basic concept, 'abrasives = wear', to these crackerheads.

A 13L engine is not going to perform like a 15L engine. Constantly mashing the throttle, working the engine to 100% capacity trying to get what a 15L does at 60%. It's hard on the engine, the turbo, and the after treatment system. Yes, that's right, the hotter that engine is running, the more soot it produces, which means everything is working harder. "The salesman told me these engines are tough as nails, they can take it." Again, the salesman wanted you to buy, and told you what you needed to hear to pull the trigger. Hey crackerhead, what do you think a salesman's job is?

The correct oil is absolutely necessary for these engines to function properly with the after treatment exhaust system. They even fill it at the factory to give us a clue. Delo 10w30, a synthetic blend, is the correct oil. Lighter oil carries soot better. With very tight tolerances in these engines, heavier oil doesn't get all the way through to the top once it becomes laden with soot. "My pappy, my pappy's pappy, and his pappy's pappy all used 15w40, good enough for them, good enough for me." This is not your father's, grandfather's, or great grandfather's engine..., crackerhead.

 

This man, right here... gets it.

 

I haven't been looking much at the paccar. The cummins seems to be in the most trucks I've been looking at. Seems like guys are rebuilding around the 600k mark. That's nuts. I've watched a few tear down videos and I was amazed. After 600k the engine was toast. Why....because of what you said about soot and abrasives. That's why alot of guys run those bypass filters to take out the soot. It was amazing how bad the top end looked at such a low mileage. Looks like someone was under there with a hammer and file.....it was bad. If things go back to normal......ever again.....I'm thinking about going the route @Midwest Trucker is and just buy a new one every couple of years. Sounds like a good plan to me. I just don't know what the best option is for me right now. Truck prices are high and options are low.

 

In my experience idle time on my DD15 has had zero negative impact on my engine or it’s emission system. 416,000 miles and uses zero oil on 20,000 mile oil change intervals. The only emissions components to be replaced are 1 inlet nox sensor and 1 outlet nox sensor. Which coincidentally seem to need replacement on other DD engines that never idle. I do idle it up to 900 for better oil pressure and hotter exhaust temps.

Heat doesn’t create soot, quite the opposite actually. Poor combustion and low combustion temps do. Heat actually burns soot and nox, why do you think after treatment systems run at such high temps?

Agree 100% with you on oil.

 

Correct, these newer engines perform better and burn cleaner the hotter you can run them. My opinion, based on what I've experienced personally, the DDEC aftertreatment system is more robust and less troublesome than Cummins, which is used by Paccar and IH.

 

Anybody know anything about the newer Mack engines? Like the e9, mp7, mp8 and such?
