I do not think it will cause a problem with your engine using the 10w30 oil if you added a quart until you can get the oil changed using correct 5w20 oil. It is better to add this oil than to run it low on oil. You should not use the thicker oil in this engine due to the oil passages in the camshafts and heads are pretty small and may starve for oil if the oil is too thick. Have the oil changed as soon as possible with 5w20 oil.
