Buying a used truck. 97 w/12.7 Detroit or 13 with ISX15

I’m sure both trucks are going to need absolutely everything but Atleast the 97 has no emissions and no elog, even if it has a Detroit In it

 

6-7mpg?

 

6 if he's drivin easy

5-5.9 otherwise

 

The S60 was a really good engine but you can’t take that California. Not sure if you can even hook ELD to it. Running your own truck might be difficult if broker or anyone requires ELD.

13 ISX you should check to make sure it did not have that bad ceramic fuel pump some years ago ISX had. The ceramic fuel pump would explode and take out the most of the engine or fuel system. They had upgraded them before they went bad. I remember couple years ISx have trouble with oil flow to top of engine and the cams were going bad for no reason they said at the time. Seems like people said years later the soot was clogging the oil passages to top of engine or something like that. Cummins never admitted to anything wrong with those engines. I don’t remember exact years you might doubt check

 

Unless the '97 has been meticulously maintained odds are it's a worn out piece of junk that'll nickle and dime you.

The Series 60 is arguably one of the best electronic engines produced. The ISX not so much.

 

You can buy 400k mile T680's and Cascadias cheaper

 

The ‘13 is way too much money. There are 2020 trucks sitting around, for that.

The mileage on a ‘20 means it’s going to need all the regular stuff an emission truck needs, which is why fleets flip them at ~500K miles. But, at least it’ll fuel mileage decently.
