I was amazed the first time I pulled the stick on my gf's Mazda Tribute with the 3.0 Duratec V6 and saw how clean the Motorcraft 5W-20 oil was after 5,000 miles. She does tons of stop and go driving, idling and this was back when the temp was 100+ for many days in a row in TX.
The inline 4 in the Acura is a kitten compared to the abuse a V10 would throw down on the same oil... you have nothing to worry about.
As a side note, we're running Delvac 1300 15W-40 in our old 1987 Integra 1.6L in the summer months and it hasn't exploded into a million pieces or anything, it's actually very happy. That engine has over 300k on it now so yours still has a couple miles to go in its useful life.
