November 26, 2010made an idiotic accident today and bought 6 quarts of 10w/40 oil to do an oil change.. after i finished putting the oil into my truck, i realized the cap said to use 5w/30.. am i hurting anything by using the 10w/40? ill go buy the 5w/30 and re-change the oil out but i figured i would ask around before doing so.

November 26, 2010Shouldn`t hurt anything as far as I know.
Its about the journey, not the destination!
November 26, 2010its not going to hurt but i would recomend letting the engine warm up a little before you start driving because of it being cold outside
November 26, 2010I actually use Mobile delvac 1300. 15w/40. It`s a heavy duty diesel oil but is good for high mileage gas engines too. Been using it for 4 years now.
November 27, 2010I always use 10W/40 and have had no problems after 148,500 miles. But, I guess it depends on how cold it is. We don`t have that problem here in Miami!
