Oil for 2014 6.2 AFM/ DOD

[alpha_omega]

I am running a 6.2 , 2014 Escalade with 97K miles.

We live in Buffalo NY

So I waited until A few weeks ago and I switched to 15W-50 Mobil 1 and immediately the engine started up with nearly no ticking.

My oil pressure was about the same as 53 PSI dropping to 43 PSI after warm up.

Before after warm up it would
Drop to 35 PSI.

I am using a plug in AFM deactivation unit.

I think I will add a block heater this summer.

I am very concerned about the engine failing since I have
to get it last 30,000 miles more.
I am retired and I drive 5,000 miles a year.


In winter I will use the block heater and a 5-50 oil

Do you park indoors? Even in Buffalo I’m not sure that you need to change your oil weight. Just keep the fluids changed and topped off properly. You have close to the same mileage I have on my Denali. Your concern should be with the transmission and torque converter more so than the engine.
That’s not to say ignore the engine, but if it’s well maintained they can last several hundred thousand miles.

These do have a lifter failure and some of them have issues with the “pill needing to be flipped” on the trans cooler lines, but realistically the only other thing you might want to keep an eye out for are the motor mounts and your coolant ‘Tee’s’ at the firewall. Since yours is a ‘14, most of the other issues from ‘07-12 were already addressed before yours was even assembled.

Did you take a chance to look at your manifold bolts yet? Here is a photo of what you’re looking for.
