By "first formulation" I meant with the motor oil in the mix being Rotella 15w40 - their conventional oil - that I ran the last OCI with the MMO as opposed to the Rotella T Synthetic 5w40 that I normally run and that is in the car for a new OCI now. I used the conventional Rotella because I figured why waste money on synthetic oil for a maintenance cleanup run with MMO. I sent the sample in just for fun, but when I saw the wear metal numbers I decided that I would do a little more analysis to see if there is more to marvel over than I ever realized. I'm going to have this new RTS analyzed at about the same mileage and decide what to do from there. If the wear numbers don't look as good as they did this last OCI with the MMO, I'm going to repeat the MMO run to see if it agrees with the first one. I'm thinking that I'll do that with MMO in some RTS next time unless I talk myself into going out and buying some more conventional Rotella for science.
Aw, I missed that your current filI was with RTS.
RTS is a fine oil, and if you don't mind spending the extra, run it with the MMO. I did that with my old RX8 (now sold), which benefitted from a thicker oil, and very much liked the results.
How does MMO thicken up the oil? Do you mean after the lighter components evaporate? How did the car "very much like the results"? Did it have higher compression than comparable engines? How did you know it was so happy?
Sometimes when I'm rubbing her throttle plate I think I can hear my car moan.
