The two prior oil change intervals were with M1 0W-20 EP, which made the engine quite noisy and the oil did not darken much. With the Valvoline, the engine was much more quiet and it ran a bit smoother. It did not darken much until around 4K miles and I changed it at 5k miles. I recently learned that other people also noted that Amsoil SS turned quite dark for them too, so I suspect that mine did not turn dark due to deposits and that I had little need of using Valvoline Restore. That's ok since I'd rather that be the case anyhow.
