Will 5w-50 harm my engine? Cause I had to pick up a Qt and I mistakenly grabbed the 50 instead of the 30 because they were right beside each other. I realized I did it when I was throwing the bottle away.

It is also full synthetic.

Its just alot thicker then the normal 10w 30.

1 quart shouldnt hurt at all.

i wouldnt mix it with your current oil

Well it is kinda too late for that Skar.
Hellion I use 5w-30.
