Proposed maintenance cycle for Cascadia w/ DD16 questions

and here I am feeling bad I’m leaving out of the yard tomorrow with 9800 miles on this oil change….

 

Detroit Diesel on their website, claims that limited duty on a DD13 motor can go 80K miles between oil changes. I'd listen to the people who made the engine.

I'm not making this up. AND it is the truth, if you run Full Syn Mobil One Extreme Duty 15-40 extreme duty you can go 125K miles between changes.

Real world, that's what I run and oil analysis says so. The air filter will break before the oil will.

In my DD13 I used to run recommended 10-30 but my oil pressure would only build to 45 psi max at full temp, when I changed to 15-40 it got to 55 psi which I'm more comfortable with. I never noticed a difference in mileage between the two weights, so I went higher.

I just pulled the top end and inspected the cams when I replaced 3 injectors and rear injector wiring harness last Monday, and the cam lobes look good for 447K miles on my DD13. Minimal wear scar, and I've had that motor at full jake and 2000 RPM for more minutes than I'd like to admit. LOL.

You have to love Detroit Jakes.

 

Yep, your a number cruncher, not a mechanic. Or a Driver.

You're not picking up what we're laying down. So there's no use responding.

Because if you don't grasp what even I've said, you're gonna end up with a bunch of trucks that get beat up by drivers who are just as clueless as you are.

And then everyone blames the trucking industry and lack of freight.

Edit...I didn't even comment on how this poster is trying to break into hauling flatbed for the "aviation industry"....

Carry on people.

 

I just drive the truck as much as possible for a rate that works for me.

Then I fix #### before, or when it breaks.

This feel good, pull the pan bs, replace all this crap every 3 services? That's just wasted money. If managing maintenence is going to be your job here, I think you'll be back to driving again soon.

Not to be rude, but if these "associates" think you're the man for the job, then you guys are in a world of trouble.

I see this fleet business going nowhere

 

I only have experience as a one man operation, so for what its worth....

If these are highway trucks I would keep it simple. Do valve set and change the oil and grease it twice as often as the OEM recommends, follow the OEM for most of the rest. Hoses, belts and tensioners every few years. Sample the oil for $30 every time and it will tell you what's up. If something needs to be rebuilt, youll know way in advance. And if something doesnt, youll know that too. I overmaintained my first brand new one and still had a catastrophic failure..... #### still happens no matter how preventative you are.

 

Well, I'm your Huckleberry, lets get down to party. I respond to the threads because most of your guys don't have the legitimate Capital to even buy a Cascadia, let alone 20 of 'em. You struck a nerve because you can punctuate.

You are just the employer I'm looking for, and to be honest, I'm the employee that knows enough, with enough experience, to tell you how you're doing it wrong.

If you want to hire someone with 30+ years of trucking experience, mechanical and engineering experience, and someone that can tell you in a nice way this idea is ####ing stupid, gimme a PM here.

Don't get you panties all in a wad when people that have experience tell you that you're spending money wrong.
