kcv67 15 Posted December 13, 2020 Report Share Posted December 13, 2020 Looking at a RV with a 2006 Cat C7 300hp 45000 miles on it. Looking for comments from people who have experience with the motor. Casey Quote Link to post Share on other sites
Austin The DieselTech 509 Posted December 13, 2020 Report Share Posted December 13, 2020 That engine is very young. CAT recommends changing the oil at 250hrs. At LeMay, we had 4 of them over the 20K hrs mark and still going strong. The C7 engine has a HEUI injection system like a 7.3 powerstroke.

stroketeck 505 Posted December 13, 2020 Report Share Posted December 13, 2020 made many miles with one in a freightliner M2 sport chassis, we never had any engine trouble. wasn't a rocket but was dependable 1 Quote Link to post Share on other sites
Abbyfireguy 719 Posted December 13, 2020 Report Share Posted December 13, 2020 The nursery I drive for owned a smaller Freightliner for many years with one in it. It was a great dependable truck until someone fell asleep and rolled the truck. Would never win any race but went up and down the hills and never missed a beat. There’s tons of those engine putting over the road reliably... 1 Quote Link to post Share on other sites

kcv67 15 Posted December 14, 2020 Author Report Share Posted December 14, 2020 Stroketeck it is in a m2 sport chassis. What is the difference between sport and commercial m2s? Besides it being lower to the ground. Quote Link to post Share on other sites
