Ever since I got the headgasket changed 30k miles ago my iron rate has tripled (from ~2ppm per 1k mi to ~6ppm per 1k mi). I suspect shoddy workmanship from the place that did it, but not sure what exactly they could've done that would increase the amount of iron showing on an oil report. Otherwise, the engine runs normally and the vehicle has been very reliable.
This is the 2nd of two runs with Castrol Euro 5W40. This time I switched to VRP 5W30 and will run it for at least 4x OCIs. The Castrol had tons of life left but I was itching to get started with the VRP regiment.
For those who are curious, sample #1 was Pennzoil Euro L 5W30 and #2 was M1 EP HM 5W30.
