Look it up on Cat forms, the C7 runs great, if you take good care of it, It likes good clean oil to protect the Heui system, It may cost a little more, but its cheap insurance, I had used various good quality oils and filters, but in talking to Cat mechanics I have gone to using Cat oil and filters, not much different in price than using other stuff, I also change my oil ao or before 7500 miles. look up adept ape videos, very informative, hears one,

But like was said start with fuel filters, both of them, also if its has sat for a long time it could have algae in the tank.
Oh, I think mine runs great, I can take off from a light and keep right with traffic
