Most recent UOA, chronic fuel diluter Ford Ecoboost 3.5, “winter“ OCI…to be replaced by some super-stout oil capable of withstanding 8500mi (plus / minus 1000) summer trip…something like Valvoline Premium Blue RESTORE. Actually I think the QSFS did reasonably OK, though not convinced it would be the best possible option over the summer…might be OK if I plan for an oil change mid-trip.
the previous UOA’s were : 5w30 Pennzoil Plat SN+ (oldest), then ~900 mi 530 Ultra Plat SN from stash, then Valvoline Premium Blue RESTORE 10w30 (more recent long OCI). There were other OCI’s: 2 per year, with the 3 summer runs on the VPBR. The VPBR has been awesome. Not sharing Dyson Analysis UOA’s on the VPBR due to NDA, though the late 2019 run shown was an attempt to get comparison between Dyson and OAI Labs…somewhat consistent. OAI reran the fuel dilution, and magically the FD dropped on 2nd analysis. I don’t remember the 1st result…now “covered up“ but higher…like 5%.
QSFS stayed in grade (better than the PennzoilPlat), didn’t hold up as well as VPBR…though that’s apple to oranges 2750 mi run vs much longer with VPBR…~$20 per gal vs $75per gal. Not sure what the oxidation & nitration results should have been for the QSFS.
Ford has been ZERO help on finding root cause of fuel dilution, denying / ignoring my attempts to diagnose. I can’t even get the tech to admit the oil smells like gas…maybe he has COVID, can’t smell anything.
Historically iron has been ~2ppm/1000mi, whereas this time was higher. i wish I knew why copper so high, on multiple UOA’s.
Motor runs fine…I think. NO noticeable misfires , NO codes. Somewhat disappointing mpg, though not abysmal…15-16 mpg highway in high-roof Transit van.
I also included a random VOA for this oil, which unfortunately doesn’t have virgin oxidation / nitration figures.
