They swich my Oil Weight

[InitialTB]

Hi Ladies and gentleman

So today I went to get my car service(09 Matrix 40k mile) at the Toyota dealer that I been going to for many years now, but this time I ask them to switch from Toyota oil to Mobile 1 synthetic oil. I was really happy with the synthetic oil, until I got home and look closely at the receipt, and to my surprise it say Mobile 1 5W-30 synthetic, is this ok or should I bring it back to the dealer? because I know that they been using 5w-20 and the owner manual and the engine cap it say 5W-20.

Please and Thanks You

It's not that big of a deal, but you might have a little less MPG due to the fact that it's a bit thicker oil at operating temperature. If it makes you sleep better at night, then take your car back to the dealer and have them switch the oil back to 5w20. Welcome to the Nation by the way!
