Re: 0-40 Mobil 1
Owners manual only recommends 0W-40, a few degrees likely will make little difference.
Owners Manual: For best performance and maximum protection under all
types of operating conditions, only use synthetic engine
oils, approved to MB 229.3 or MB 229.5, such as Mobil 1
SAE 0W-40.
I also checked the manual for my SRT8 and it also recommends 0W-40, except the chart has arrows in both directions, above 100 and below -20.
