Hello! Been lurking daily for 9+ years. Just Joined.
My 2015 Subaru Forester 2.5i 6spd that was purchased 4/14 says to use 0w-20 synthetic only in the owners manual.
When first purchased I checked the Mobil 1 oil site. It also said 0w-20. Just check the site a few days ago, site has changed.
Now it says: "Based on what you've told us, your vehicle manufacturer recommends a 0W-20 viscosity and synthetic oil. A 0W-30 viscosity can also be used. We offer these motor oils to help protect your vehicle."
My oil temp per the Forester readout (and my Edge CTS) has hit as high as 230F on the hottest day. A/c was on traveling 75mph up a 2 mile grade.
I would say my average 1 year warmed-up oil temp 216F.
My 6spd turns 2750rpms at 70mph. I have read (on the Forester forums) that the CVT turns 2200rpms at 70mph.
So my questions: Why does Mobil 1 say I can use 0w-30? Should I stick with 0w-20 year around? Use 0w-30 in summer and 0w-20 in winter? 0w-30 year around? Does it matter?
Really like this vehicle and want to keep it until the wheels fall off.
Your thoughts?
