@Viper10000 Anything notable in the Blackstone comments section?
I'm also using Ford's full synthetic in my Expedition but no oil samples yet. Will see how the 3.5 EcoBoost looks now that I'll be able to sample if without dumping all the oil. I don't drive the Expedition enough to do more than the "or 12 months whichever is less" oil changes.
All engines "shear" oil. Four years of sampling the Royal Purple 5W-30 full synthetic in my 2006 Honda S2000 (2.2 liter, 8400rpm red line) shows the SUS Viscosity @ 210°F and the cSt Viscosity @ 100°C both at the low end of the "should be" range. Mileage doesn't seem to matter much with this engine and this oil. Last annual change was at 2004 miles and the numbers are in the same average range as changes as high as 6600 miles previously. All fine. I started tracking engine wear on this car because it's long out of production and the only source of engines is a few very expensive places in Japan.
Would be nice to know the SUS and cSt viscosity data for these oils right out of the can. Anyone?
