    2012 6.7 Cummins 11,000 mile OCI Valvoline CK4

    I took the radiator cap off and watched it this morning at startup. To see if any bubbles were present on a cold startup. I didn't see any. I added about maybe 6 ounces of coolant to put it back at the minimum line, which is where I keep it at. First I've added since changing it out 40,000 miles...

    I've seen uoa's from other 6.7 Cummins that had higher potassium levels with aluminum similar to mine. No elevated sodium levels though.

    I thought I had took a picture of the back of the jugs. But i didn't. This is what I seen on the Walmart site. I haven't seen any other info yet. This is not the max life. Didn't see no use info on it on there. http://www.walmart.com/ip/Valvoline-Heavy-Duty/49660456...

    2012 Ram 3500 valvoline 15w40 7685 miles

    Bought some Rotella t6 5w/40 while they had a good deal on it. Wear rates are pretty much the same. As the 15w/40 oil. I put more of the t6 back in after this oil change. Probably use 15w/40 for the next change and save the other 5w/40 for late next year. I might send a virgin sample of mystik...
