I have emailed Ford tech to get their response.
Either this dealer made a mistake, is choosing to use 5w-20 oil on all vehicles to save inventory/money, or he correct and 5W-20 oi9l is now spec'd for the 4.0.
We will see
Can't really answer your querstion but I change my Mobil 1 twice a year on all my vehicles.quote:

This seems as good a time as any to ask: Aside from possibly voiding the maunfacturer's warranty...what is the downside (if any) of long term usage of a heavier viscosity..for example, using 5w30 in an engine spec'd for 5w20, or 10w30 in an engine spec'd for 5w30? In these examples, I wouldn't expect significant problems...am I wrong? I know enough not to put 20w50 in a 5w20 application.
Use 5w30 all year around, the 30 after the "W" is what you worry about.quote:

My manual says 5w30.
The oil cap says 5w30.
Where does this info on the use of 5w20 come in?

I plan on using 5w30 Mobil 1 in the cold months and 10w 30 in the hot months.
You spin a rod bearing and Honda will claim it was because you used the wrong viscosity oil. Will they prevail? Who knows. Always best to use the spec'd oil while under warranty.quote:

Can they really void my warranty using this because it's not the
wt spec?
I am a believer in full synthetics so am not interested in the Amsoil group III 5W-20.
I am considering using Red Line 5W-20, what thinks you experts.
