This is a SUPERB car! I was shocked at how smoothly it rode on the terrible streets of Newhall with those extremely low profile tires. Quiet, powerful, excellent handling - I am impressed! It was good meeting The Critic in person! We've known each other for at least 20 years at BITOG...

1 qt in 15 miles 😳 That’s CRAZY! Is it a typo?

Yes, that is what I meant. In my opinion.

Good question!

With the damage/destruction to refineries in the Middle East, which oils are most and least likely to be affected?

From my experience I’d have to say Valvoline Restore and Protect.

Pretty snazzy car!

I can only imagine... very funny!

BINGO!! You may not be an "expert," but you know and understand a LOT about this subject matter.

Forgive my ignorance but what is an OPE engine?

It seems that under ideal conditions and in a superb engine, 10,000 miles is doable with Valvoline Restore and Protect. I still believe (there's that word!) that with a turbocharged GDI engine the intervals should be shorter. But, that's just me...🤷‍♂️ FWIW, I am running Valvoline Restore and...

I'm a big believer in the merits of Valvoline Restore and Protect, but without knowing the vehicle and engine, I would say that I would never exceed a 5,000 mile interval with a turbocharged GDI engine, and would most likely not exceed 4,000 miles. For me, that's probably true regardless of oil...

I went to the Ford website, and sure enough, it shows E-load range tires for the Expedition. What is striking, and possibly a typo, is that it lists the tires as P265/70R18E. As a former tire dealer, it struck me as either a very new development in the tire industry (that a P-metric tire would...

I know that the use of AI here is frowned upon, but I didn't know what this meant, so I Grokked it, and I think others may find this useful, too. Per Grok: "**"Full shear" conditions**, as used by Gokhan (a well-known member on BITOG/BobIsTheOilGuy forums), refers to engine lubrication...

Historically, I've bought from Tire Rack. This most recent purchase was from America's Tire, which is essentially the brick and mortar owner of Tire Rack. I needed tires right away, and I couldn't wait for a shipment.

Eric said that it appeared to have 7,000mi oil change intervals with dealership bulk oil. Not optimal, for sure. At least they used OEM oil filters.
