5W20 or 5W30?

[valpoyaris]

So I got an oil change the other day and the guy asked what oild I wanted, I told him 5W20 (which is what was in it since the day I got it a year ago), he wrote down 5W20, but then he put in 5W30. Is there any concern/problem running that or should I go back a bitch up a storm and make them switch it out? I only ask because it seems to be bogging down when I accelerate since then. Thanks for the help.
