I never use after run oil. I have an Axial .28 Spec 1s, and it has about 8 gallons on it now and has only seen after run oil a handful of times. The ONLY time i use ARO is when I know the engine is going to be sitting for a few months without running. However, if its in the house, and not out in a cold garage where it is subject to temperature changes, it should be fine anyways. You havent hurt anything at all. No need to worry. [8D]
