Detroit DD's are the same. Some have had trouble too. I can't imagine trying to diagnose that.

 

Try and tell some of the dough-heads on this site that 50k mile oil changes are excessive and they think you're retarded lol.

 

Agreed.
If I did 50,000 mile changes in my trucks now that they are retired they would have lifetime oil in them. I could go 5 years and only have 3,000 miles on some of them. Lol.
I always do 8,000 and sweated if they hit 10,000. But they are all 45 plus years old and still running so no one would ever convince me I wasted oil and money doing that.

 

I never really understood the theory behind basing drain intervals off mileage either. 10k on a truck that never idles vs 10k on a truck that idles 8 hours a day is not the same.

I remember one of my dad's old trucks. Bought new, traded after 4 years. About 350k kilometers on the chassis but the engine had over 10k hours on the clock. And that truck worked. Hauled just over 40 metric tons of wood out of the sticks every day, 10 months a year.

 

Don’t know about you guys up north but down here in the days of mechinical everything on trucks no one cared about hrs. They always went by miles. Trucks didn’t come with hr counters and 95% of the tachometers didnt have that feature. Some savvy guys installed after market counters and went by them but most of us simple folk didn't care. All though Farm and construction equipment always had them and went by hrs. Using hrs on trucks has been a recent thing that seems to have come along with the ecm.

 

The bad thing about the old hr. counters too was if you parked the truck over night or any other time you were shut down and mistakenly left the key on it would have put hrs on the counter with the engine off. Not real accurate.

 

For our Mack dump truck, I tried to do service based on the hour meter since the truck puts on low kms but high hours.

But the Boss’s son won’t allow that.

Truck puts on between 700-1,000 hours by the time it reaches 12,500 miles. Oil is like tar after.

I don’t drive that truck so no longer bother with trying to work it.

 

Should look up service intervals for newer ag equipment to show him. Last I knew John deeres longest interval was probably 500hrs and that's to long for my taste. Especially for something out in the dirt. I always figure when they start burning oil it's time to change

 

Lester: we have construction equipment as well. We change their oil at 300 hours...

For some reason, they think the trucks can easily do 20,000 kms/12,500 miles between oil changes while doing short trips.

I know owners manual also explains oil change intervals in hours too, but they’re doing what the oil salesman says the oil is good for. Pfffffft

 

Most Caterpillar equipment seems to run at a 500 hour service interval. 250 hour for severe service applications.
