Hey guys, ran into a problem this past weekend when I was changing oil...I use Pennzoil 5w-30 and poured a quart of 10w-30 in on accident with the 4.5 quarts of 5w-30. Would this have wrecked anything or been bad for the engine?...I did end up draining it all out
...rather safe than sorry

Look back or search at the 5,000,000,000,000,000 oil related threads. If you are so new to automobiles that you would drain out your oil for this, you need all the education you can get. Read at least 400 posts before you follow up this question.

BTW I don't like to mix different BRANDS because of the different additive packages, but diff weights of the same band are OK.

I use a 10w30 and 10w40 mix of Havoline DS.

No puppies killed. Funny....not.
One needn't be a pro to search and read any of the about 1,970,000 web pages found in a simple GOOGLE search for "motor oil +mixing".
How 'bout reading 50 of those sites and giving us a brief synopsis? Make this thread worthwhile.
