Vehicle: 2009 Hyundai Accent 1.6L, 6000mi total. Oil in use a little over 2 months. 90% of trips < 5mi. 50% of miles are hwy
Blackstone comments: This oil sample has the look of a wear-in sample, so don't let that high copper throw you. Copper tends to run high early on and then trend down to average levels after a few oil changes. It is from bronze parts. We're kind of surprised that more wear metals aren't high, but we're certainly not complaining. Usually we see high silicon too, from sealers and sand-casted parts, but your silicon is normal. The trace of gas should go away next time. The TBN read strong at 4.9, showing plenty of active additive left. Try 5000 miles next time. Copper should still improve.

The good: wear metals, except copper, were low. OEM filter did the job. TBN holding up well.
The bad: Copper very high. Oil sheared alot for 3000mi. Flashpoint is low. Don't know how much fuel is a TR. Drove vehicle 30 mi on hwy before OC.
I changed oil on this car @ 500mi & 1500mi & it seemed to work in flushing out wear metals except copper. I'm glad I did, as I can only imagine how much copper were in those. These engines must put out a lot of copper, for the universal average is a whopping 28. Felt bad about dumping the Mobil 1 after only 3000 mi, but am glad not to have 93ppm of copper circulating in my oil & 3k is what Hyundai suggests for severe service. Going to run 5k oci's until wear settles down, then on to 7500 max that Hyundai allows for warranty. Refilled with Royal Purple 5w20 that I had in my stash as my manual says ok to use SL or SM. I have heard that these high rpm engines with small 3.5qt sump can be tough on oil. Will see how the RP holds up.
I posted this as I know that many are now running the Mobil 1 0w30. I bought the oil about July 10, so I don't know if it is the new formulation or not, but I suspect it is. It was very smooth in my engine. The Royal Purple is more raspy. Probably still in the process of putting that mirror finish on the engine internals...ha Tired of typing now. Have a good weekend
