5W-30 for longer engine life?

[ThirdeYe]

It shouldnt make a difference. My car made it over 500k using dealership bulk 5w20. Im only using a 30 grade now to curb some consumption.

Given a choice, 5W30.

The motor is Multiport so we probably do not have the same concerns of the GDI or turbo motor. Owner's manual list 5w-30 as the highest weight recommended for the 2.0 Atkinson Cycle motor.

Remember that there is no proof that a thicker oil protects better. Lots of high mileage cars out there running on 20 weight oils. So choose whatever you like better.

Sounds good, guys...thanks.
Just for the fun of it, I will try 5W-30 for my first oil change which I think I will do at around 3000 miles, than do 6000 OCI.

Like my Fusion. I use 0-20 and my engines perform very well.
As a matter of fact yes with 10,000 mile oil changes and they look great under the valve cover !


CT8 nailed it with this comment---and do not forget he was doing it XX years ago before anyone even thought of running a 20 wt oil
