Question for Heartland Express Drivers

@Powder Joints works there I believe. He might know.

 

I believe Schneider does theirs at 80k

 

Just call Heartland and ask them

 

Wow. I don't know how you could get 80K out of any oil in a DEF engine. Well, actually any engine.

Bulkmatic was doing changes at 60K because that's what manufacturer recommended, but after 46K it would start burning oil to try and stay alive.

 

I do mine at 20k, just because its easier to just look at the odometer and be able to know...

 

Heartland has a history of keeping their trucks in top condition.

I remember people buying them directly from the company and hauling them off the yard when I worked there 15-20 years ago.

I saw them do a service/oil change in less than 15 minutes one time. Several mechanics hitting it like a Nascar pit crew right before closing time.
In that regard, they are the best. The care of the trucks was the key to their success. Very efficient outfit.

Trucks went through an inspection lane every time they hit the yards M-F 0730-430 and Saturday 8-12. Guy would pop the hood, check air pressure on tires, walk beneath it in the pit looking for issues.

Rare issues while out on the road were fixed the same day.

 

Though worlds apart, I change oil on my 1995 12.7 Detroit based on oil samples. I added a low micron , one gallon bypass filter to it - send samples in every 10k miles. Generally I change at 30-40k miles, based on oil health. Base number (acidity) is usually the factor, mainly due to low miles on the unit/annually. (50-60k annually).

Last company truck we drove was a 2015 DDEC 15 - and the spec was 50,000 mile oil changes, as I understand, one of the filters served as a bypass oil filter.

Without sampling and lab analysis, oil is often thrown out well before it's safe serviceable life.

I'd drop by Heartland with a box of donuts and have a chat with the service manager and gain some insight.

 

If they run High Capacity Oil Systems you can run longer, Heartland samples the oil between changes, and call so in early. The tractor I drive tractor I drive has over 350K does not burn any between changes, Get an oil change every 60,000 miles.
