I bought a stock 02 C5 coupe, only 60k miles. Rides smooth and gets great gas mileage.
Believe it or not? the C5 is gonna replace most of our Yukons trips of going back and fouth,1000 miles ea way, several times a yr between our 2 homes (TX & CO mtns). We no longer have large dog(s).
no. My owners manual was written in 2007. A lot has changed since then, oils too.
If crankshaft was shedding iron lead and copper from the bearing(s) would be thru the roof long before the iron from the crank shows up.
The report in post#1 shows that the oil didn't shear.
AWD and always properly inflated which helps me achieve the great reliability and gas mileage.
as I stated in post#1 I changed all 4 recently
I'm a light aircraft owner (25+ yrs) and a retired pro pilot.
