oil viscosity difference between model years

[blackphoenix]

When I had my 09 vibe, the manual said to put 5W-20 in. Now in my 2010 vibe, it says to use 5W-30. I am using the same 2.4L engine in both cars. Yet, on my 2010, the oil cap says 5W-20. What is going on here? I think that most new 4 bangers use 5W-20 if I'm not mistaken. Should I change the oil to put 5W-20 in?

There have been other threads on here about the 2009 - 2010 manuals saying one viscosity and the oil caps saying another. The general consensus has been to stick with the 5W 20.

I am wondering if it is a printing error in the manual since the cap is the same. To make sure it is the right cap the next time you are around a GM dealership stop and go to the parts dept and ask the part number and what it should say on the cap

The 2010 Owner's manual says 5W-20

Depending on year, either Toyota long life concentrated red or the newer Toyota super long life pink, 50/50 premix. Zerex Asian Phosphated HOAT (P-HOAT or POAT) 50/50 premix might be an acceptable replacement. Other Asian OEM's P-HOAT coolants and Motorcraft deep green P-HOAT would probably be acceptable too.Anybody signed up for a 2009 Vibe at the Gmownercenter.yahoo.com to see which manual they are pushing?
