2017 VW GTI 6-speed with EA888 gen 3 2.0l TSI DI engine. Just turning 40k miles. First oil analysis was Castrol Edge 0w-30, this analysis was Pennzoil Platinum Euro 0w-40. Both bought years ago during AZ and WM clearances paying no more than $2/qt. PPE 0w-40 was in service during the severe winter we just had for just under 5k miles, Mann filter had 10k miles on it. I drive 90% highway around 35k miles/year. For some reason my Fe numbers are lower than any other EA888 than I've seen. I think I will be going to 10k intervals based on these numbers, maybe 20k on filters. VW UK says 2 years and 20k with my driving style. I have one more Wix kit so I think I will give it a go. The slight viscosity drop doesn't worry me, it was still thicker than Castrol after the same time.
