10w-30 oil for the 4.7

Well I mistakenly changed out my oil 10w-30 full syn. today...will I experience any ill effects from this? Think it will be okay until next oil change or should i change it out now?

I wouldn't worry about it if i were you . The Hemi with MDS is the only engine that really HAS to have 5w20 .The same 4.7 L engine from 99-04 only spec'd 10w30 or 5w30 and it was only after they put it in the wk chasis that they changed that .

5 and counting :05 WK 5.7 HEMI
