If you tell me what you're curious about, perhaps I can address those points and be more helpful. That said, It works very well in my car, in my circumstances, and I especially like it on long, higher-speed highway trips compared to the 0W-20. Over 3,000+ miles there is no observable drop in the oil level, and that includes the times I've made some long-distance, higher-speed trips.Just curious, how well does 5w30 work in your Camry? We have the same engine and I’m curious about using 5w30.
However, please note that I'm using Mobil 1 Extended Performance, different brands might behave differently in your car. When I bought the car, I used Castrol Edge 5w30 EP (gold bottle) and during that OCI I needed to add a small amount of oil (btwn 1/4 and 1/2 quart) to maintain the level.
I doubt if I'll ever return to 0W-20 although I may try some Mobil 1 ESP 0w30 that I have. In fact, I know I'll try it. I should also note that I'm a Mobil 1 guy, don't use other brands (except for that one time when I first bought the car, but that was a unique circumstance).
HTH, YMMV
