If the oil is changed at the VPC, and it is done solely to get Penske’s (and MB's) racing sponsor’s product into the car it would a significant waste and expense. If the oil is changed as an initial flush, I wish we were so informed. Maybe Penske is as smart as we think, or maybe this is SOP directed by MB***. It would be interesting to know if the Euro and Canadian smarts have the sticker, or just the U.S.
My delivery oil came out the day I returned home from the dealer. I was guessing that the Mitsu engine came out of Japan filled with their own non-MB 229.5, full-synthetic, ENEOS Premium Hyper 5W-30, a product of the Mitsubishi-Nippon Oil Corp. (JP’s largest). I didn’t note any obvious “fines” in the oil basin, but in the time it took to open the filter for inspection (where there was a bit), the oil sitting cooling in the basin developed an odd, waxy, surface scum that I have never seen before – when I ran a wire across the surface it left an open channel. I’m glad that batch of whatever it was came out of the car along with what else may have come out with it. Perhaps a single early VPC flush isn’t quite enough. The filter was replaced with a Tokyo Roki/Yamaha 5DM-13440-00, an identical clone of the OEM T.R./Mitsu 1230A040 for the next 500 miles. When that filter was opened, the oil was quite dark and with very few fines.
*** The Suprex 450s were delivered with a “break-in” oil (“erstbetriebsmotorenöle”) per MB Sheet 225.10. The gassers used it for 15,000 km and the diesels for 20,000 km before changing to MB 229.5 service oil. I cannot determine if the 225.10 break-in oil was fossil, semi-synthetic, or full-synthetic – my guess is fossil.
