at 30K and third oil change @ 10K, my oil analysis went to the waste oil furnace, it said the oil was perfect. First change @10K was Castrol 0W40, last two were Mobil 1 0W40.
Once the oil temp reads the temp number, you're all set to do what you please.
Either Mobil 1 or Castrol GTX - never had oil issues with either one.
Running the OE Castrol 0w-20, pushing the car very hard up a twisty road in NC/SC, I saw a maximum of 235F with an ambient temp of 75F. My averages with normal driving are close to yours. These temps are well within the oil's capability.
i been using it religiously for now 85k miles, i have tried Quartz Ineo 5W30 502 Spec oils made my engine produce more heat and valvetrain noises. The Castrol Edge 0W40 I use now tops out at 212, normally sitting between 205 and 210. With the 5W30 Quartz it was constantly sitting at 227-237 which is pretty significant.
this oil is my most trusted, been using it since new with the best results ( i tried Mobil1 0W40 and a 5W30 Total Quartz once each and oil temps were 15-20 degrees hotter in similar ambient temps and conditions with both of those so i decided not to use them again).
They also have the 5qts of Castrol Edge 5w-40 for under $30. I've been running that in my cars since 2005.
Last change I did was with Castrol Edge 0w-20 no issues.
I've always run conventional Castrol 20/50 in my Gti's (past and current Turbo) without issue.
Well, just got back the test results on for our oil analysis, here are the comments: " Nothing showed up in this sample that's too much of a surprise, though aluminum and copper are perhaps a little higher than expected. New parts wearing in tend to leave a lot of metal in the oil and that's what we suspect is going on here. You ran this oil pretty long for factory oil (we realize you were probably only following the oil life monitor). So that's why aluminum and copper are on the high side. No matter--everything should improve now that you've changed this fill. The TBN read 1.9, getting low but still okay. Potassium is from the EGR system. "
