It's red. Need more info than you provided. The years range from about 2000 to current I believe. Drastic changes have been made across that time.
Can't remember the server went down couldn't pull it back up. I believe it was a 2010 navistar pfl 400- 450 hp automatic
Need some information. Seriously you might try explaining what you want to know. I'm guessing that you need some info for a web based testing?
When they are running and not in the shop or broke down on the side of the road, they're said to burn diesel fuel.
International went big with their own engine (Maxxforce) for a time. When other truck makers went with DEF in thier engines International did not. Their Maxforce technology pretty much sucked all well as the engine. They got sued by the EPA and ended up bringing back the cummins ISX in their trucks along with now using DEF. The isx in a International since then is probably no better or worse than the same engine in other brands of truck.
The Cummings ISX has a good reputation. It will depend on who drove it and for how long. If you are buying used, take it to a mechanic and have them go over it.
I drove a international with isx. Good Fuel mileage and we never had a issue . No engine is perfect they all have issues , just don't get a maxxforce.
