This was a 4100 mile run of Mobil 1 Advanced Fuel Economy 0W-30 in a '23 Ford Bronco with the 2.7L ecoboost twin turbo on a Fram Synthetic Endurance cartridge filter; 24,500 on the odo. It was mostly 6 months of winter short trip city driving with a 700 mile road trip about 3000 miles into the run. I sent this sample to SpeeDiagnostix and WearCheck. Also sent it to Horizon but it has been nearly 3 weeks and I'm afraid it got lost at their lab, so I just got these two results. I switched this Bronco to VRP 5W-30 and will stick with the endurance filters for now. I was using the M1 AFE 0W-30 because it was the only 0W-30 easily available that met the Ford spec, but I learned over the last few months on BITOG that 0W isn't really necessary even where I live, and the Ford spec isn't anything much beyond API SP/ILSAC GF-6a. The VRP seems like it might offer some extra protection against deposits, has a slightly higher HTHS, and it cost the same as the M1. Also LSJ straight up recommended the VRP over M1 ESP when I asked him what oil I should try next.
I paid $25 extra to wearcheck to get the Gas Chromatography fuel dilution service but when they first sent me the result it still didn't have it. When I called they initially balked at doing the GC test because they said the viscosity was "close enough" and that "that test is expensive". When they reserached that I'd paid the extra they agreed to do it, but somehow only about 30 minutes later they emailed me a report with the fuel dilution. Maybe they really can do it that quick, I don't know. I'm not sure how Wearcheck got 2000 ppm calcium considering I've done 4 VOA's for this oil and the highest one on calcium was 1031 ppm. I also am a wee bit skeptical of 2 ppm iron. I asked them to consider a rerun but they blew it off and just said "VOA's are tough to compare to". Not really sure what to make of all this other than I probably wasted more money entertaining myself with UOA's.
I got the extra Particle Count from Speediagnositx and it seemed to indicate that there wasn't much there, from what I read, (obviously I'm no chemist or scientist) this particle count isn't much different that what an unused oil would contain. Fuel dilution was a little higher this time even though viscosity was also higher. Maybe the shorter run led to slightly less viscosity breakdown/shearing despite the dilution, I don't know.
