I really want to know if the light weight oil recommended by Honda is good enough for the tropical heat of a Florida summer (8 months of high temps > 85 F, lows > 75 F), highs > 90 F every day JJA, as I like to keep the car as long as feasable from a mechanical standpoint. My lifetime average is ~15 yrs for keeping a car, and frequent changes with the proper oil isnecessary to accomplish this.
