Below is a UOA of my wife's Malibu. Most of the miles were accumulated during the winter months 50-50 hiway and city. I did use a bottle of Gumout all in one after I read this report.

The first sample was from the dealership they stated Mobil1 but who knows. I can't remember what the 2nd was, sorry.What was the oil in the other columns?
Does your wife tend to do extended warmup of the vehicle in the winter? 5-10 mins? This is an early implementation Di turbo?Below is a UOA of my wife's Malibu.

If the Fuel Dilution were not an issue on this run, this HPL Oil could have gone 10,000 miles or maybe 12,000 miles.Fe has spiked a bit this run & can't be sure it's either from fuel dilution or HPL cleaning. You could always try a different lab next drain to see how it lines up. The other wear & oil is in good shape.
If reports still evidence 2x iron after a rinse and repeat - It could point fuel wash or to a DP/EP imbalance. The Mg compound is 3x typical treatrate. Fuel dilution needs to be addressedDoes the High Iron mean that HPL has done some cleaning?

Further testing to narrow down where or what is causing, to see the trend upon future samples, could shed some more light on what is causing the added wear. We can speculate that it's the fuel but the previous sample didn't have the same effect on Fe. Interesting to speculate though & I'm not sure what HPL says about how far their oils can go or do they just rely on UOA testing?If the Fuel Dilution were not an issue on this run, this HPL Oil could have gone 10,000 miles or maybe 12,000 miles.
Think they're talking about Detergent package (additive pack) treat rates/ratios might be off.What is DP/EP imbalance?
Basically, in this UOA sample there could be a bit of oil leftover from his previous OCI. So, we may need at least 2 runs of the HPL Oil with UOA's of the next 2 runs of HPL.Think they're talking about Detergent package (additive pack) treat rates/ratios might be off.

I also see the high fuel % in the previous Fall Season sample in 2021- so could be a bad spray pattern on one or more injectors.
My Mini has a BMW B48 with direct injection putting out over 300 HP. I've run HPL Supercar 0w30 for 10,000 miles. Just changed it for another 10,000 mile OCI.Do we have anyone on BITOG running HPL on a GDI engine for 10K miles+
Regular 87 octane. I would say 70% Meijer gas (top tier) and 30% Murphy (not top tier)Bob
Friend just bought one of these with the 1.5.
Curious what primary gasoline brand you buy and what octane level?
Also, is this HPL analysis the PCEO, PPCEO, or the PPPCEO?
Yep she tends to remote start in the winter months and let it warm up for a few minutesDoes your wife tend to do extended warmup of the vehicle in the winter? 5-10 mins? This is an early implementation Di turbo?
