So anyway...I just did an oil change and realized afterwards that I used 5W-30 instead of the usual 10W-30 I always use....Should I notice any differences? Going into winter now (Chicago winter)...what are the pros or cons to this mistake?

 

Don't think you will notice anything. You're talking about 5W difference - pretty minimal.

 

it is probably better to use 5w30 since winter is getting closer. i always use 5w30 in my engine and it still runs. it is good for lower temperatures.

 

Yeah just checked the factory service manual....5W-30 recommended from <32F

 

For winter months, the 5W-30 will flow a little better at startup, you'll be fine...

 

ditto

 

I just realized i put 80w-90 gear oil in for my oil change! haha just kidding yeah i think i normal use 5w-30 and my motor purrs like a kitten.

A little lifter rattle at start up, but holds pressure REAL good!

 

I live in Chicago too, my wife has a Dodge dakota 8cyl in her truck I have to use 5W-30
thats what the manual calls for, I think your fine.
