Opinion on INTERNATIONAL LT SLEEPER - CUMMINS, X15

You're gonna get a wide variety of answers on this.

I personally have no experience with the International LT trucks, so take this for a grain of salt. But the last International I drove was a 2008 IH 9200i. I loved everything about it except the Cat engine and auto shift transmission. But that's another story for another thread. Was probably the nicest riding truck I'd driven up to that point in my career. Interior was laid out very well.

All that being said, you can buy a Kenworth and in two years it'll be trash if you do no maintenance. Likewise, you can buy an International and it'll last 2 million miles or more if you maintain it properly.

It's all in how it's maintained.

 

Haven’t seen to many issues with these units besides the typical DEF issues that everyone has. Just make sure every Cummins recall has been done and have that serial number on the clutch checked out to make sure it’s not one of the bad ones.

 

I have a 2018 international LT, X15 efficiency (with a Pittsburgh power tune) it had 324K when I bought it, just turned 400K this week. It’s a 10 speed, I drove an automatic, but didn’t like the way it shifted.

I had a diesel force cleaning done, an overhead ran, and had the tune done a few months after I bought it. I put all new tires, brakes and drums, and shocks all the way around within the last 7 months.

Its been a good truck, it was a fleet truck, so I’m sure minimal maintenance was performed before I bought it, but now I take good care of it.

 

im driving and 2019 International LT x15 auto. a few weeks ago it starting sounding louder than usual in low gears (fan noise) i can even hear it come on and off at high speeds… what is going on

 

Check the exhaust flex section between the turbo and DOC inlet. They break there all the time.

 

Didn't find a lot of threads on that combo. I'm looking to buy one 2020 with this combo and 330k miles on the clock. Wondering why are they so much cheaper than other trucks and also, what'd you say on mpg and if this combo 400hp+10 speed doesn't feel slow?

 

Internationals are cheaper trucks anyway, some are pretty bare bones on the inside. I had my truck turned up to 500hp. My 90 day average is 8.1 mpg, but I’m drive 63-65mph and had a performance tune done at Pittsburgh power.

 

I’m a company driver in a 2018 leased from Ryder with that setup. Mine has 360k miles on it, and aside from minor issues, it’s doing fine. Despite long oil change intervals (80-90k) it runs strong and isn’t using any oil. As for mileage, mine is governed to 70 mph and I’m averaging around 6 mpg. When it was set slower, it was a little better. I drove a Kenworth T-660 before it, and spent a couple of months in a T-680 during a change to local driving (it was nice being home every night, but the money wasn’t as good), and honestly, I prefer the International. The lease is up this year, though, and I’ll probably be in a brand new T-680.
