Kenworth T600 2007 with C13 just need some maintenance tips please

Hello Guys,

I have finally made deal on buying Kenworth T600 2007 with C13 twin turbo motor dropped new in September 2010. It is having 621k miles on it now. Truck seems fine. Running well. I just need some maintenance tips from you all running or had run C13 /C15 as i am running this motor first time in life:

1. What interval should i change engine oil/filters
2. which engine oil should i use?
3. Should i club it with Lucas?
4. Tune up ?
5. Any other prevantive maintenance tip?
6. Anything to look specifically, i mean the things having higher chances of failure?
7. Best RPM for good fuel mileage?
Any tips, suggestions or laughs will be much appreciated.

thank you my fellow truckers.
