INSITE REPORT - PRE PURCHASE INSPECTION

[NoTruckYet]

Looking at 2009 International Prostar with Cummins ISX and AMT 795,000 miles. $25,000 new tires - drives well.

I asked the used-truck sales lot permission to put on dyno, and the owner, who is also a long-time Cummins tech said 'No-Way' on the dyno, could ruin a good high mileage engine. Instead, he hooked up InSite computer and pulled the following data, at idle. -This is an incomplete list but I understand the things that are not on the following list.

PARAMETER VALUE UNITS MIN MAX

The Short Term Map 1 - I would have to attach a picture. 9.7% of time engine at idle. 9.8% of time between 800 and 1200 RPM. 38% of time engine has run between 1200 and 1400 rpm over 29,655 hours. 6/10 of 1% of time, engine has run between 1600 and 1800 rpm. 50% of total across all RPM ranges.

They have cleaned / serviced egr, put new turbo on the truck.

The oil was last changed when it came off lease - mileage could not be determined but it was a local/regional. They would allow an oil analysis - but without mileage since oil change unknown may not give accurate readings. The oil is NOT as clean as Rawze's truck - it's pretty dark, but not jet black.

Many advise to just 'go out and buy a new truck' but that is not in the cards.

Looking for a better understanding of the report and suggestions on check-out. They have cleaned the EGR pipes and the owner of sales dealership is on Cummins engine development team and knows every nut and bolt of a cummins. Everthing on lot has a cummins.

I flew to CA to look at truck and making a decision - leaving Sunday 2/17.

Thanks for y'alls input.
