Correct engine oil for 2010 1.8L? 5W30 or 5W20?

[SuperVibeMan]

Hi Folks,
What are you all using in your vehicles? My owners manual says SAE 5W-30 but the oil filler cap says SAE 5W-20. Which is correct? I've been using the 5W-20 Napa Synthetic but want to know if I should trust the manual or the filler cap? Have any of you faced this same situation? Was the manual printed in error or the wrong cap installed? I appreciate any feedback.

Thanks!

I used 0w20 for winters and 5w20 for summers for the time I owned my Vibe.

Toyota engine and Toyota Matrix manual specifies 5w20. GM for whatever reason chose to specify 5w30. Bottom line is if Toyota is specifying 5w20 I wouldn't have any problems in putting in 5w20, but put in 5w30 if it makes you feel comfortable.

5W-30 won't hurt it, but you should be using 5W-20 or 0W-20.

The owner's manual is wrong. The GM Service Manual specifically states:

"For temperatures above -20F (-29C), use 5W-20. 5W-20 is best for the vehicle."

Later it states that 0W-20 should be used when temperatures may go below the above.

I believe the owner's manual also specifies the wrong transmission fluid. I think it says DEXRON. These trannies take WS though, which is also specified in the GM shop manual.

Also, check the oil filler cap. Mine says 5W-20.

Manual was a misprint, use either 5w20 or better yet use 0w20 if you can find it.

Thanks much for the clarification guys.....I really appreciate it! 5W20 it is!

Both our 2009 GTs get 5W-20.
