EPA Crackdown on Deleted Trucks

Most times they don’t as well around here unless they catch on that there is something not right, then they pull the vehicle over.

 

I thought you had to do 10,000 mile oil changes to keep the warranty ?

 

Every engine is different. The Paccar MX13 and the Detroit DD15 and DD13 have some bypass filtration built in from the factory. I’m not familiar with the Detroit’s but on a Paccar if you meet the parameters you can stretch out to 75k service intervals. On mine I do 40k intervals because I’m usually over 80k gross weight.

 

I will ask next time i talk to him but my nephew drives for a company that does heavy haul , usually 130-140,000 lbs
with 600 HP 18 speed W900s and I’m almost positive they do oil changes every 10k

they still had an engine lose a cam at 250k miles .
I never heard of losing a cam in old trucks, is that something with the emission engines ?
I owned several 80s model trucks with mechanical injection pumps and several of them had worn rings and burned a gallon of oil every 500 miles and some had worn main bearings and had 4 pounds of oil pressure at hot idle , but never lost a cam .

they have a few four axles W9s that regularly gross 210,000.
Their 13 axle setup with the jeep and booster weighs 79k empty I think

 

X15 doesn’t have a bypass filter to my knowledge. On the low end, the severe duty interval for an MX13 is 30k miles. Normal line haul with idle time greater than 20% it’s 50k miles. Normal line haul with less than 20% idle time is 75k miles.

 

They run the oil 75k miles without changing it ?

 

Yes. That’s the point of bypass oil filtration. I don’t push mine that far because I don’t meet the criteria. I change oil at 40k miles.

 

I just did some reading, this doesn’t apply to the heavy haul examples above, but if certain criteria are met Cummins says 80k service interval on the X15.

 

Wow

injuatvtextwd him and he said they change the oil and filters every 10k

think he said they do a manual regen every morning.
Since they idle all night , and never turn the engine off under a load.
Sometimes their rig doesn’t get turned off for 7-10 days

 

I know, you’ve stated that previously. As I said, the operation you keep talking about doesn’t meet the criteria that Cummins sets to extend drains. For most highway trucks with new engines, however, dropping the oil at 10k would just be wasting money and throwing away good oil.
