I added to oil to my vehicle today as it was low I looked at the stores guide book for what oil my 1999 contour use's and the guide book read "5w-20" so I bought it and added it to my car after pouring only a quart in the car I look up on the hood and there is a sticker that says "use 5w-30 motor oil only" so because I used 5w-20 will this damage or ruin my vehicle?
