The thing is, people are NOT doing "extended" oil change intervals (OCIs) with MMO in the crankcase.....most users of MMO are using the MMO in the crankcase in the range of 1-5k.....I don't think I've heard anyone going any further than that....?
I know Marvel and Turtle Wax keep the product fairly "open ended" and only state "how" to use it on the bottle, they don't give any suggested oil change interval but I'd think the product should be able to hold up for a reasonable OCI.....
