quakerstate Q 5w20 synthetic

well I went and decided to try the quaker state Q 5w20 full sythetic. it instantly feels smoother and quieter just after 3 days (about 350 km), also changed the filter with original honda part. so far seems great ,warms up faster and idles so quiet it's hard to tell if my engine is running,ie 3.0 litre v6. anyone else try the Q line ?
